Product Description:

The MSK075C-0300-NN-S1-UG1-NNNN is an IndraDyn S synchronous servo motor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. Its standard design uses an internal permanent-magnet rotor to deliver accurate speed and torque control in industrial automation cells. When paired with IndraDrive controllers, it converts electrical energy into mechanical rotation for indexing tables, gantry axes, and other motion stages that require dynamic response during continuous duty. It also uses an optical feedback system to maintain precise positioning throughout its operating range.

Heat produced during operation is dissipated by natural convection, which eliminates the need for external fans or liquid circuits and helps support compact cabinet layouts. The stator winding uses code 0300, which indicates electrical resistance and inductance suited to mid-range torque at typical bus voltages. Position feedback is routed through a rotatable 240° connector, and the signal is transmitted over the Hiperface serial interface; inside the encoder, 128 signal periods are generated optically for fine interpolation. An electrically released holding brake provides 23 Nm of static torque so vertical axes can remain secured when power is removed. The housing has an IP65 rating that helps block dust ingress and water jets commonly encountered on factory floors.

Mechanical coupling to the load is through a plain shaft, allowing backlash-free clamping hubs or shrink disks. The feedback element is a single-turn optical encoder, so absolute position is retained within one revolution. The motor size is 075 and the motor length is C, giving a balance between continuous power and overall dimensions for medium-frame machines. Thermal endurance is supported by insulation class 155, allowing reliable service at winding temperatures associated with a 0 to 40 °C ambient operating range.
