Product Description:

Bosch Rexroth Indramat manufactures the MSK075E-0300-NN-M1-UP0-NNNN, a member of the MSK IndraDyn S Synchronous Motors series. This synchronous servo motor provides closed-loop rotary motion for axis positioning, feed drives, and coordinated handling modules in industrial automation cells. Its standard housing and electronic commutation let a compatible drive controller regulate torque, speed, and position with consistent response during repeated motion cycles. The design suits applications that need accurate starts, stops, reversals, and stable operation under changing load conditions.

This model dissipates heat through natural convection, so no external blower or liquid circuit is required. Free airflow around the housing helps the motor shed heat during continuous operation, which keeps installation simpler in machines that do not use auxiliary cooling. The encoder connector can be turned through 240°, which helps with cable routing when surrounding components limit access. The feedback channel uses the Hiperface protocol for bidirectional data exchange and absolute position transfer, and optical scanning produces 128 signal periods per mechanical revolution for stable feedback processing at the drive. The housing is sealed to IP65, and the winding system uses insulation class 155 for thermal durability during normal operation.

The motor uses a shaft with keyway for secure torque transmission to couplings, pulleys, or gear inputs that require a positive mechanical connection. Continuous service is supported across an ambient range of 0 to 40 °C, which fits common indoor industrial conditions when the motor is installed with suitable clearance. It is supplied without a holding brake, so static load retention must come from drive torque or an external braking device when the axis is stopped. This layout can reduce complexity where back-driving is acceptable and where a separate machine brake already handles vertical or suspended loads.
