Product Description:

The MSK075D-0200-NN-M1-UP0-NNNN is a synchronous servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It supplies closed-loop torque and position control to automated axes, allowing drive controllers to synchronize motion in packaging, material-handling, and machine-tool stations without mechanical gearing. The encoder connector can rotate 240°, which helps cable routing in tight enclosures.

This model uses the standard design and occupies the 075 frame in the longer D housing, yet it rejects heat through natural convection rather than forced air. A protection rating of IP65 seals the housing against dust and low-pressure water jets, so cabinet placement is optional. Continuous operation is specified within an ambient range of 0 to 40 °C; outside that window, derating or auxiliary cooling is required. Mechanical power leaves the unit through a shaft with keyway, giving positive drive engagement for couplings and pulleys. Size code 075 and winding code 0200 identify the motor frame and winding combination used with matching drive parameters. No internal brake is fitted, so the load must be held by the drive or an external clamp when power is removed.

The feedback assembly communicates through the Hiperface interface for position data transmission. Inside the enclosure, an optical scanning system produces sinusoidal signals with 128 signal periods per mechanical turn; when interpolated by the drive, this resolution supports precise positioning. Multiturn data are stored in nonvolatile memory, letting the controller read absolute position over a multiturn absolute range without homing. A thermal insulation class of 155 (F) permits continuous winding temperatures up to 155 °C, aligning with the motor’s convection cooling path and helping prevent premature varnish breakdown under cyclic duty.
