Product Description:

The MSK071C-0300-NN-M1-UP1-NNNN is a servomotor built by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is an IndraDyn S synchronous servomotor intended for precise position and speed control in industrial automation lines, where electronic drives coordinate motion axes. The motor’s size 071 frame and length C active stack place it in the medium torque class of the platform while keeping the housing compact for cabinet or machine-mounted installations.

Thermal management relies on natural convection, so heat dissipates through the finned housing without external blowers or liquid lines. The cast-aluminum enclosure carries an IP65 ingress rating, which blocks dust and low-pressure water jets that are common near conveyors and filling equipment. Continuous operation is supported between 0–40 °C, which matches typical plant floor ambient conditions for this motor. Windings use Class 155 insulation, giving thermal headroom before aging becomes critical. The electromagnetic design uses winding code 0300, which sets the voltage constant and rated current values used by the IndraDrive amplifier. A rotatable 240° hybrid connector routes both power and feedback through a single molded plug.

Position feedback is supplied by an optical encoder that provides Multiturn Absolute data through the Hiperface bidirectional interface, allowing the controller to recover rotor angle and revolution count immediately after power-up. The sensor delivers 128 signal periods per revolution, supporting fine interpolation for smooth velocity loops. A spring-applied, electrically released brake delivers 23 Nm of static holding torque, preventing load movement when power is removed or the line is idle. Mechanical power leaves the motor through a shaft with keyway, which mates with standard couplings and pulleys while helping prevent slippage under cyclic loads.
