Product Description:

The MSK070E-0150-NN-S1-UG1-NNNN synchronous servomotor is produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S servomotor, it converts drive output from an electronic amplifier into precise rotary motion for automated positioning, feeding, or process axes in industrial machinery. Its standard build suits modular drive platforms used in packaging, printing, and assembly cells. This motor is intended for applications that require repeatable positioning and stable speed control during continuous machine operation.

The motor uses frame size 070 with length code E, a geometry that balances torque density with compact installation depth. Its copper windings follow code 0150, giving electrical characteristics matched to compatible MSK drive controllers. Cooling relies on natural convection, so heat is released through the housing without fans or liquid circuits. The enclosure has an IP65 rating that keeps dust and low-pressure water jets out of the stator chamber. The permitted ambient temperature range is 0 to 40 °C, allowing full current without derating in that range, and insulation class 155 supports winding temperatures below the Class F limit during demanding duty cycles.

The feedback system uses an optical single-turn encoder, and its signals pass through a rotatable 240° connector that helps with cable routing. The Hiperface protocol provides absolute position recovery after power-up, and the encoder supplies 128 signal periods per revolution for fine velocity control. An electrically released holding brake rated at 23 Nm helps prevent shaft movement during downtime or an emergency stop. Torque is transmitted through a plain shaft, which simplifies coupling to gearboxes or belt pulleys. The rotatable connector also helps route power and feedback cables without placing unnecessary strain on the connections.
