What methods can be used to judge the quality of hybrid stepper motors

 ‌‌‌1. A brief introduction to hybrid stepper motors

Hybrid stepper motors are a type of motor that combines the advantages of permanent magnet stepper motors and reactive stepper motors. It has high output torque and high step accuracy, and is widely used in industrial automation and precision control, especially as a drive device in economical CNC machine tools. Its high precision, high reliability and good speed regulation performance make it perform well in these fields.

2. The main structure of hybrid stepper motors

The main structure of hybrid stepper motors includes three parts: stator, rotor and armature. The stator is usually composed of a combination of a reluctance winding and a wound winding of a traditional stepper motor. The stator is equipped with a multi-way winding structure and a permanent magnet on the periphery; the rotor is composed of a magnet and a small reluctance magnetic needle of a traditional stepper motor; the armature is composed of a regulating reluctance and a power supply, which is used to control the rotation direction and step of the motor.

3. Design requirements for hybrid stepper motors

1. Performance requirements: Hybrid stepper motors need to meet specific performance indicators, including step angle accuracy, torque fluctuation, etc. The motor should work normally under the specified power supply and load conditions to ensure reliability and stability in practical applications.

2. Structural requirements: The rotor of the hybrid stepper motor itself is magnetic, which makes the torque generated under the same stator current greater than that of the reactive stepper motor. However, its structure is relatively complex, the rotor inertia is large, and the rapidity is low.

3. Material selection: Hybrid stepper motors are usually made of high-temperature resistant permanent magnets and high-quality cold-rolled steel sheets to ensure the reliability and stability of the motor. In addition, the selection of high-quality bearings and appropriate surface treatment can also improve the performance of the motor.

4. Environmental adaptability: Hybrid stepper motors should have good environmental adaptability and be able to operate stably in different working environments. This includes characteristics such as high temperature resistance and moisture resistance.

5. Test methods: The national standard specifies the test methods for hybrid stepper motors, including performance tests, environmental adaptability tests, and durability tests. These test methods ensure that the motor meets national standards and provide a basis for quality control and selection.

4. Quality judgment method of hybrid stepper motor

‌1. Appearance inspection: First observe whether the overall structure of the motor is complete, whether the cable connection is normal, and whether there is no damage or breakage. At the same time, check the nameplate or label on the motor to understand its model, voltage and other information to ensure that it meets the equipment requirements.

‌2. Resistance measurement: Use a multimeter to adjust the motor to the resistance range (such as 10K ohms), disconnect the power connection and signal line connection, and measure the resistance value of the motor coil. If the displayed resistance value is close to infinity, it means that the motor coil is basically normal; if the displayed value is very small, the motor may be short-circuited or open-circuited. In addition, the resistance values ​​measured at both ends of the motor should be almost equal, otherwise it may be caused by motor bearing wear, stator and rotor misalignment, etc.

‌3. Power-on test: Connect the motor to the power supply and observe its working status. Under normal circumstances, the motor should be able to work normally, rotate flexibly and without abnormal sounds. If the motor does not turn or turns with difficulty, it may be a motor failure.

‌4. Speed ​​and torque detection‌: Use a tachometer or other measuring tools to measure whether the speed and torque of the motor meet the requirements of the specification. If the speed or torque is significantly lower than the nominal value, it means that the motor performance is poor.

‌5. Noise detection‌: During the operation of the motor, use a noise meter or other measuring tools to record its noise level. If the noise is significantly greater than the nominal value, it means that the motor performance is poor.

‌6. Life test‌: In actual applications, the motor is tested for a long time to observe its service life. If the motor fails or its performance deteriorates in a short time, it means that its quality is poor.

‌7. Professional equipment detection‌: For some complex parameters, such as phase, phase angle, etc., professional motor testing equipment can be used for detection. These devices have high precision and can more accurately judge the quality of the motor.

How to improve the stability and service life of right-angle planetary gearboxes

1. Introduction to right-angle planetary gearboxes

Right-angle planetary gearboxes‌ are gearboxes used for deceleration or acceleration transmission, with the characteristics of high transmission efficiency, small size, low noise and long service life. Its core structure includes sun gear, planetary gear and inner ring gear. This structure can achieve high-efficiency transmission, and at the same time has high load-bearing capacity and long service life. ‌

2. Working principle of right-angle planetary gearboxes

The working principle of right-angle planetary gearboxes‌ is based on the special structure of planetary gears, and its core lies in the rotation and revolution of planetary gears. The axis of rotation of the planetary gears is not fixed, but is installed on a rotatable bracket, which is called a "planet carrier". The planetary gears can not only rotate around their own axis (rotation), but also rotate around the axis of other gears with the planet carrier (revolution). This movement is similar to the movement of planets in the solar system. ‌

3. Methods for improving the stability of right-angle planetary gearboxes

1. High-quality materials‌: The right-angle planetary gearbox is made of high-quality materials, with precise gear engagement, low noise, and no obvious wear after long-term use, thereby improving the stability of the equipment. ‌

‌2. Precision manufacturing process: Through high-precision CNC machining technology, such as gear grinding and gear hobbing, the gear tooth profile accuracy is ensured to reach IT5-IT6 level, so that the gear is evenly stressed during the meshing process, vibration and noise are reduced, and a stable transmission ratio is maintained.

‌3. Compact structural design: The output shaft of the right-angle planetary reducer is at a 90-degree angle to the input shaft. This design enables the reducer to achieve efficient power transmission in a limited space, which is particularly suitable for occasions with limited space.

‌4. High transmission efficiency: The multi-stage transmission design of the right-angle planetary reducer enables it to have a higher transmission efficiency, usually up to more than 90%, reducing energy loss and improving the stability and reliability of the equipment.

‌5. High load-bearing capacity: The multi-point contact planetary gear system design enables the right-angle planetary reducer to have a higher load-bearing capacity, which is suitable for heavy-load occasions and further improves the stability of the equipment.

4. Methods to extend the life of the right-angle planetary gearbox

‌1. Regular cleaning and maintenance: Keeping the inside of the gearbox clean is the basic condition for extending its service life. Any impurities or dirt entering the gearbox will affect and damage its rotating system, thereby reducing its service life. Regularly clean the oil and dust on the equipment to ensure that the inside of the gearbox is clean.

2. Control the working temperature: Maintaining the normal working temperature of the gearbox can prevent the deformation of parts due to excessive temperature difference, ensure the normal operation of the gears, prevent excessive noise, and thus extend the service life. For gearboxes working in high temperature environments, heat dissipation devices such as radiators or cooling fans can be installed to avoid excessive temperatures that accelerate the failure of lubricants and wear of parts.

3. Reasonable use of lubricants: The use of lubricants is essential to the operation of gearboxes. Delayed use of lubricants or use of inferior oils will cause immeasurable damage to the gearbox. Regularly injecting an appropriate amount of lubricants and ensuring their quality can effectively reduce friction and wear.

4. Avoid overload and impact: Strictly use the rated torque and power of the gearbox to avoid overload operation. In the mechanical system design stage, the workload should be accurately calculated and a gearbox of appropriate specifications should be selected. Reduce the impact load during starting and stopping, adopt a slow and smooth operation method, and protect internal components.

‌5. Check and replace worn parts: Regularly check the relevant parts of the gearbox, such as oil seals and gaskets, and replace damaged or loose parts in time to ensure the normal operation of the gearbox.

‌6. Follow the instruction manual: Use the gearbox correctly in accordance with the instruction manual and avoid arbitrary and improper use, which can minimize the damage to the parts in the machine.

Linear guide rail usage precautions and design principles

1.A brief introduction to linear guide rail

Linear guide rail is a mechanical guide rail used to support and guide moving parts to reciprocate linear motion in a given direction. It usually consists of two parts: a track (slide rail) and a slider. The slider is equipped with internal circulation balls or rollers, which can achieve smooth, high-precision linear motion on the track and can withstand a certain load. ‌

2.Components of linear guide rail

1.Guide rail: The guide rail is the main part of the linear guide, providing a track or path for linear motion. It is usually made of wear-resistant and high-strength carbon steel or alloy steel. ‌2. Slider: The slider is installed on the moving part and cooperates with the guide rail. The rolling body slides on the guide rail to achieve linear motion. ‌

‌3.Rolling body: The rolling body is usually a steel ball or steel column, which rolls between the slider and the guide rail to reduce friction and improve motion efficiency. The rolling element of the ball type guide rail is a steel ball, which belongs to point surface contact, with a small load capacity but small friction resistance; the rolling element of the roller type guide rail is a steel column, which belongs to line surface contact, with a stronger load capacity but a higher price.

‌4.Retainer: The retainer is used to keep the rolling element in the correct position in the slider to prevent the rolling element from falling off.

‌5.Housing: The housing surrounds and protects the internal rolling element and retainer, while providing necessary support and protection.

3.Design principles of Linear guide rail

‌1.Automatic fitting principle: In order to make the guide rail high in precision, the guide rail pair must have the characteristics of automatic fitting. Horizontal guide rails can fit by relying on the weight of the moving component, while other guide rails require additional spring force or roller pressure to fit.

‌2.Full contact principle: Within the length of the fixed guide rail, the moving guide rail should be in full contact with the fixed guide rail at the two extreme positions of the maximum stroke to ensure that the guide rail pair can complete full contact during the contact process, thereby achieving a perfect state.

‌3.Principle of compensation for force deformation and thermal deformation: The guide rail and its supporting parts will deform when subjected to force or temperature changes. This deformation should be considered during design so that it can be deformed into a corresponding shape. For example, the crossbeam guide rail of a gantry machine tool is made into a convex shape to compensate for the bending deformation caused by weight.

‌4.Principle of proximity of dynamic and static friction coefficients: The dynamic and static friction coefficients of the guide rail contact surface should be as close as possible during design to improve repeated positioning accuracy and low-speed stability. This is easier to achieve with rolling guides and sliding guides with plastic plates.

‌5.Principle of non-interference in precision: The various precisions of the linear guide rail should not affect each other during manufacturing and use to ensure a higher precision coefficient.

‌4.Precautions for use of linear guide rails

1.Ambient temperature control: The ambient temperature should not exceed 80°C, and the instantaneous temperature should not exceed 100°C.

‌2.Installation and removal of the slider: When removing or replacing the slider, a dummy rail should be used to assist in installation, and the guide rail should be avoided from being removed unless necessary.

‌3.Use in special environments‌: Special attention should be paid when using in special environments such as frequent vibration, high dust, high and low temperatures.

‌4.Lubrication and maintenance‌: Wipe the anti-rust oil first and then seal the lubricating oil for use to avoid mixing lubricating oils of different properties. When using lubricating oil for lubrication, adjust according to different installation methods. After filling the lubricant, push the slider back and forth for at least 3 slider lengths, repeat more than 2 times, and confirm that the oil film on the surface of the guide rail is uniform.

‌5.Storage and protection measures‌: When storing linear guides, make sure to apply anti-rust oil and seal them in the designated envelope, place them horizontally, and avoid high and low temperatures and humid environments.

‌6.Handling and protection‌: When carrying heavy linear guides, more than 2 people or use handling tools to avoid personal injury or damage to the workpiece.

‌7.Safety and protection precautions‌: The slider and guide rail may fall due to weight after tilting, so be careful. Avoid disassembling the slider by yourself to prevent foreign matter from entering or adversely affecting the assembly accuracy.
