  • Selection of Couplings for Integrated Closed-Loop Stepper Motors

The integrated stepping motor coupling is mainly used to connect the integrated stepping motor shaft and the driven shaft to transmit torque, and needs to have more precise transmission performance.

1. Zero clearance: the coupling is not allowed to have a gap during the transmission process;

2, high rigidity: the coupling does not allow the hysteresis of the transmission, otherwise it will seriously affect the accuracy of the integrated stepper motor transmission;

3, low inertia: on the basis of ensuring the transmission strength, the weight of the stepper motor coupling should be reduced as much as possible;

4, good flexibility: precision stepper motor coupling, not only requires high rigidity, but also needs to correct the various deviations between the drive shaft and the driven shaft generated during the installation process.
