The definition of hollow shaft stepper motors is based on a design with a hollow hole in the center of its shaft. This design allows the axial direction to penetrate the space, allowing the transmission of materials, signals, light, etc. through the axial space, thereby optimizing the mechanical design and facilitating wiring. In addition, the hollow structure facilitates the transmission of light beams, cables and wires, reduces volume and weight, reduces noise, and is relatively simple to manufacture and use.

1.Hollow structure: The shaft is hollow, which is convenient for connection with other mechanisms to achieve flexible motion control.

2.High precision and high speed: The gap between the stator and the rotor is very small, generally between a few microns and tens of microns, to achieve high-precision position control. There is no mechanical friction and resistance of traditional motors, and high-speed rotation can be achieved.

3.High efficiency and long life: The control system adopts digital control to achieve precise current and time control, and high energy conversion efficiency. Due to the small gap between the stator and the rotor and the use of high-strength materials, it has a long service life.

1.Use electronic switches and sleep mode: These two methods can effectively reduce the energy consumed by hollow shaft stepper motors when they stop running. The electronic switch cuts off the power supply by detecting whether the motor has stopped working, thereby preventing the motor from continuing to consume energy. The sleep mode sets the motor to a low power state. When the motor no longer needs to run, it will automatically enter a low power mode, significantly reducing energy consumption.

‌2.Frequency converter adjustment: By properly adjusting the speed of the frequency converter, the hollow shaft stepper motor can be operated in the best energy-saving state. This can reduce the running time of the motor, thereby achieving energy-saving effects, and will not affect the service life of the motor.

‌3.Use high-efficiency motors: Choosing high-efficiency stepper motors can significantly save energy. Although the price of high-efficiency motors is higher, their design is more reasonable, energy consumption is lower, and service life is longer, which is more economical overall.

‌4.Reduce energy-saving voltage and improve power factor‌: When the asynchronous motor is lightly loaded, reducing the external power supply voltage can achieve energy saving. In addition, by connecting a capacitor of appropriate capacity in parallel at the output end of the induction motor for reactive compensation, the power factor can be improved, reactive loss can be reduced, and electric energy can be effectively saved‌.

‌1.Cleaning work‌: Keep the surface of the motor clean, use compressed air to blow away the dust, and wipe the surface dirt clean. This can prevent dust and grease from accumulating, avoid machine clogging, and ensure the normal operation of the motor‌.

‌2.Check parts‌: Regularly check the various parts of the motor, including the stator core, coil, rotor pole coil, etc., to ensure that they are in good condition. If a fault is found, it should be repaired or replaced in time‌.

‌3.Bearings and lubrication‌: Observe the oil quantity and oil quality of the bearing to ensure that the oil quantity is sufficient and the oil quality is good. If the oil quantity is insufficient, it should be added in time. At the same time, clean the oil ring to ensure that the oil ring is clean during the next operation‌.

‌4.Environmental requirements‌: Hollow shaft stepper motors should be stored in a clean and well-ventilated warehouse with an ambient temperature of -40~+50℃ and a relative humidity of no more than 95%. Be careful and gentle during transportation to avoid collision and impact. Avoid contact with corrosive substances such as acids and alkalis.

‌5.Connection maintenance‌: Make sure that the signal line, motor line and power line are connected and firm to prevent poor contact from causing heat and burning the plug and socket. The power supply should be supplied through an isolation transformer to protect people and equipment.

‌6.Thermal protection and lubrication‌: When the thermal protection of the motor is continuously activated, it is necessary to find out the cause and eliminate the fault before re-operating. At the same time, check the lubrication condition regularly to ensure that the motor runs in a good lubrication state to reduce wear and extend the service life.
