Product Description:

The MSK071E-0300-FN-M1-UG0-NNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Designed for precision positioning and speed control, it connects directly to IndraDrive controllers found in packaging lines, gantry stages, and material-handling stations. By combining compact electromagnetic geometry with permanent-magnet excitation, the unit converts drive current into repeatable torque and supports closed-loop automation where high cyclical accuracy and efficient thermal management are required.

Thermal regulation is achieved through liquid cooling, allowing continuous operation at peak current without relying on forced air over the housing. Feedback is carried by a Hiperface optical encoder that delivers 128 signal periods per mechanical revolution, so position interpolation by the drive reaches very fine resolution. The encoder plug is rotatable through 240°, simplifying cable routing in tight enclosures, and its sensing stack records shaft turns with multi-turn absolute capability, eliminating the need for homing after power loss. A standard mechanical design and winding code 0300 match the torque constant to MLD-class drives, while the motor is supplied without a holding brake to minimize inertial load on the axis.

The housing has an IP65 seal that keeps dust ingress and low-pressure water jets from contacting the stator windings. A plain shaft transmits torque through friction-locked couplings, and the 071 frame with length code E provides a balanced ratio of inertia to peak torque for mid-range axes. Class-E insulation is exceeded by the stator’s class 155 system, enabling winding temperatures well above ambient conditions. Continuous duty is permitted within an ambient range of 0–40 °C, and operation outside that range requires derating.
