Micromech (www.micromech.co.uk) is pleased to launch its TMCM-078 stepper motor drive module with coil currents up to 7A and 75V.

The TMCM-078 stepper motor drive is made for bipolar two-phase stepper motors, operating with motor coil currents of 0.7A to 7A (rms) (9.8A peak) and voltages of 15V to a maximum of 75V.

Depending upon the application, a high RPM of up to 256 micro steps or a high accuracy is possible, according to the press release.

A sensor-less load measurement capability can detect mechanical blocking, thus it can substitute reference switches plus the needed wiring.

The inputs for the direction, step and enable signals are optically isolated. The motor current is reduced to an adjustable level in standstills (standby) to prevent the motor from heating up unnecessarily, as well as to prevent the waste of energy.

All the outputs and inputs can be linked with JST crimp connectors or screw-pluggable connectors.

The module is available in rugged aluminum housing measuring 145mm x 96mm x 33mm.
