Product Description:

The MSK100B-0450-NN-M1-BP1-NNNN is manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It is an AC servomotor intended for closed-loop positioning and speed control in industrial automation. This motor is suited for axes that require repeatable motion and stable speed regulation during regular machine cycles. The unit follows the standard design for this series, uses winding code 0450, and occupies the 100 frame size with the B length option. A power connector on side B simplifies cabling, and the electrically released holding brake secures the shaft when the drive is de-energized.

Thermal management is handled by natural convection, so the motor dissipates heat through its housing without forced airflow. Position feedback travels over the Hiperface interface, enabling digital communication with compatible drives while carrying position and motor data on a single pair of wires. Inside the encoder, a system with 128 signal periods per revolution generates incremental tracks, and the optical encoder principle helps maintain stable feedback signals as operating conditions change. Because the feedback device is a multiturn absolute encoder, shaft position remains available after a power cycle, which reduces the need for a homing sequence at startup. This arrangement allows the drive to process commutation and position information through one integrated feedback system.

The electrically released brake delivers 32 Nm of static torque, which is enough to hold typical loads on this 100-frame motor without auxiliary clamping. The motor also uses insulation class 155 in the winding system. Environmental sealing meets IP65, so dust and low-pressure water jets do not compromise the windings or encoder compartment. Continuous operation is specified within an ambient range of 0 to 40 °C, and outside this range the motor may require derating or additional cooling. Mechanical power is transferred through a shaft with a keyway, allowing direct coupling to pulleys or gearboxes while maintaining secure torque transmission.
