Product description of hybrid stepper motor


1. Material quality: The coat is 304 stainless steel, the water jacket is the high compression casting aluminum tube, the red copper coil.

2. Mechanical size 100% meet the requirements, to ensure that there is no greater error in the use process

3. Automatic assembly line

    Automatic assembly line, improve production efficiency, low cost without human operation, one line down intelligent mechanical automatic


4.Strictly control the production of parts to improve the quality of parts

5.Automatic machine operation, stable automatic work, high processing efficiency.

6.Electromagnetic furnace optimization design, lift torque, reduce temperature rise, so that the motor running smoothly


General Specifications Item Specifications


Heat dissipation considerations

The reliable operating environment temperature of the driver is usually within -5℃ ~45℃, the temperature of the driver is within 65℃ when the driver is working, and the temperature of the motor is within 70℃ when the driver is working. When necessary, a fan is installed near the driver to force heat dissipation, so as to ensure that the driver works within the reliable operating temperature range


Primary Competitive Advantages:

Quality assurance:


     1. All stepper motors have CE and RoHS certification
     2. All motors are tested by a toasting machine for 72 hours
     3. All the motors will be shipped after testing
