Product Description:

The MSK075E-0300-FN-M1-UG0-NNNN is an IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It is built for repeatable positioning and speed control in automated machinery, where it works with compatible drive controllers to convert electrical commands into precise mechanical rotation for feed axes, transfer units, and other servo-driven assemblies. Its operating profile suits machines that need quick response, stable speed regulation, and accurate motion under changing loads during continuous industrial use.

Heat is removed through liquid cooling, allowing the motor to sustain rated current without depending on ambient airflow and helping it remain stable in enclosed machine layouts. Motion feedback is generated by an optical encoder that communicates over the Hiperface protocol, and the encoder provides 128 signal periods per revolution for accurate position capture. Because the feedback system is multi-turn absolute, it retains position information across multiple shaft revolutions and keeps reference data available after power cycles. The motor is supplied without a holding brake, so any load that must remain fixed at standstill needs external restraint or drive-generated torque.

The housing has an IP65 rating, which helps protect the windings and bearings from dust and low-pressure water jets when the motor is installed near production equipment or in damp work areas. Permissible ambient operation is 0 to 40 °C, and temperatures outside that range can affect thermal performance or lead to condensation during idle periods. Power is transmitted through a balanced plain shaft that mates with couplings or gearboxes without keyways, helping minimize runout in connected drive components. The windings use Class 155 insulation, allowing elevated internal temperatures while maintaining the thermal endurance expected for industrial servo duty.
