The TMCM-078 stepper motor drive module from Micromech is designed with coil currents up to 7A and up to 75V.

It is designed for bipolar two-phase stepper motors can operate with motor coil currents of 0.7A up to 7A (rms) (9.8A peak) and voltages of 15V to a maximum 75V.

Depending on the application, a high accuracy or high RPM of up to 256 micro steps is possible, said the supplier.

A sensorless load measurement capability detects mechanical blocking and therefore can substitute reference switches plus the required wiring.

The inputs for the step, direction and enable signals are optically isolated. To prevent the motor heating up unnecessarily and also to avoid the waste of energy the motor current is automatically reduced to an adjustable level during standstills (standby).

All of the inputs and outputs can be connected using screw-pluggable connectors or JST crimp connectors.

The module is supplied in rugged aluminium housing measuring 145x96x33mm.
