1、Reliable Work: Can directly connect to the load and run at low speed without gear reduction in a state closing to stalling. Thus a high torsion to inertia ratio can be generated on bearing shaft while eliminating error caused by reduction gears. 2、Quick Startup: Quick in start and stop, also ensures accurate control on frequent CW and CCW rotation, and the number of pulses determines the motor position. 3、Broad Utility: Allows for wide application on 3D printer, CNC machine, robot and so on, practical, reliable and high in working efficiency. 4、Better Design: Having been through fine workmanship, the internal rotor is coated with glue to prevent burrs on the surfaces after oxidation and grinding of carbon steel, which may increase the noise. 5、Easy to Install: Light in weight and compact in size as well, the convenient installation can be quickly completed within minutes.
