3 Mechanical and Electrical Interfacing

The PD20-1-1210 consists of the QSH2018-33-06-002 NEMA8 / 20mm stepper motor with 0.6A RMS rated

coil current and 17.5mNm holding torque, the TMCM-1210 controller / driver electronic for up-to 0.6A RMS

motor coil current mounted on the backside of the motor and an integrated hall sensor based magnetic

encoder. Please see also the TMCM-1210 hardware and ﬁrmware manuals for more details.

NOTICE

Note:

In order to make proper use of the integrated hall sensor based magnetic

encoder (the sensor IC is placed on the bottom of the pcb) the TMCM-1210

electronics should not be removed/moved relative to the motor. In case the

integrated encoder feature is not used, the electronics may be moved or even

removed from the motor and placed somewhere else according to application

requirements.

3.1 Dimensions of PD20-1-1210

The overall length of the NEMA8 / 20mm ﬂange size stepper motor and the TMCM-1210 electronics

mounted to the backside of the motor is about 46mm without motor shaft and without mating connectors
