Compacta MS12

Slip-on geared motor Compacta MS12


  • 3-phase AC motor
  • Terminal box
  • Any transmission
  • Thermal protection
  • IP 54
  • Plastic 1st gear stage

Depending on the gear ratio, the Compacta MS12 shaft-mounted gear motor with the optional integrated control unit version provides a drive speed of 3 to 193 rpm and a nominal torque up to 142 Nm. The drive motor has a compact design, making it ideal for applications in reversing mode with narrow installation conditions. Standard drive motors are splash-protected (IP54), optionally jet-protected (IP65) and explosion-protected in accordance with ATEX 95. Additional options increase the number of application options substantially.

Furthermore, design-related adjustments are also conceivable for larger quantities so that the drive motor can be adapted individually to certain requirements.
You can find projects that have already been implemented here.

The Compacta series covers output speeds of 0.45 to 193 rpm and a torque range of 10 to 1600 Nm with the four sizes MR6, MS12, MR30 and AG160.

The output speed of Compacta gear motors with DC motors varies with the output torque.

Please note: The gear motor can be overloaded by 50% for brief periods. Single-phase AC and DC motors may stall.

Please contact the manufacturer regarding the following operating conditions:
• Temperatures below 0°C (single phase AC and DC motors: below 10°C)
• Temperatures above 40°C
• Strong vibrations
