Product Description:

The MSK070C-0150-NN-M1-UP0-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. Classified as an IndraDyn S synchronous servomotor, the unit converts electrical power into precisely controlled rotary motion for axes that require repeatable speed and position profiles. When integrated with a compatible drive controller, it supplies closed-loop torque for pick-and-place modules, forming tables, or feeder conveyors where compact, fast-response motors are preferred over bulkier induction alternatives.

The motor is cooled by natural convection, which means thermal dissipation occurs through surface radiation and ambient airflow without forced fans; installation must leave clearance around the housing to sustain its continuous rating. Position feedback is generated by an optical encoder that uses the Hiperface serial interface; this protocol carries absolute position and electronic nameplate data to the drive over two conductors. Inside the scanning head, an optical sensing track delivers 128 signal periods per mechanical revolution, and the capture is of the multiturn absolute type, so the controller retains shaft position across power cycles without needing a homing routine. The encoder connector can be rotated through 240°, simplifying cable routing in tight cabinets.

The mechanical side of the motor uses a shaft with a keyway, allowing positive torque transfer to pulleys or couplings without additional clamping devices. With a frame size of 070 and a length code of C, the unit balances inertia and continuous torque for mid-range servo axes. The stator winding marked 0150 sets its rated voltage constant and current demand, and it uses the standard housing design so no liquid or forced-air sleeves are present. Because the motor is supplied without a holding brake, external measures must secure vertical loads whenever power is removed.
