Product Description:

The MSK075E-0450-NN-S3-UP0-NNNN belongs to the MSK IndraDyn S Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is an IndraDyn S synchronous servomotor intended to deliver controlled torque and rapid positioning for machine tools, packaging axes, and pick-and-place gantries. The motor integrates into drive systems that need high feedback accuracy and compact dimensions, matching Rexroth servo controllers while occupying the 075 frame class used for mid-range continuous power. Its compact form helps it fit tightly spaced axis layouts where responsive servo motion and reliable positioning are both required.

Heat is removed through natural convection, so no external blower or liquid circuit is required, and the housing releases heat directly to the surrounding air. The encoder connector is rotatable through 240°, which lets the cable exit in multiple directions without placing unnecessary strain on the plug. Inside the connector, a Hiperface single-turn encoder uses capacitive scanning to provide position data with 16 signal periods. This feedback arrangement supports stable commutation and position reporting, and it remains well suited to applications where dust or vibration may be present around the motor.

The housing has an IP65 protection rating, which helps keep out dust and low-pressure water jets in general factory environments. It is intended for continuous service from 0 to 40 °C without derating under normal ambient conditions. Torque is transmitted through a shaft with a keyway, which supports common pulley or gearbox connections and allows positive torque transfer through keyed hubs. The windings use insulation class 155, allowing operation at temperatures associated with Class F insulation. Because the motor is supplied without a holding brake, external holding or clamping is required when the load must remain fixed at standstill.
