Technical Parameters
Stepper motors are not constant torque motors; the higher the running speed, the smaller the output torque. Therefore, when paying attention to the holding torque parameter of the motor, one should also focus on the output torque of the motor at the actual working speed (refer to the dynamic torque curve). We recommend reserving a 1.5 times margin to avoid step loss of the stepper motor under overload conditions.

Notes
The above recommended “Suitable Driver” is a pulse-type stepper motor driver. HDB motors can also be supplied with:
Bus-type stepper motor drivers (RS485, CANopen, EtherCAT communication control, etc.)
Intelligent stepper motor drivers (with position tuning, built-in PLC programming functions, etc.)
