Product Description:

The MSK101C-0450-NN-S1-BP2-NNNN is a synchronous servomotor built by Bosch Rexroth Indramat and assigned to the MSK IndraDyn S Synchronous Motors series. Designed as a compact torque source for CNC axes, packaging equipment, and transfer lines, the motor converts electrical energy into tightly regulated rotary motion that can be coordinated by Rexroth drive controllers. Within an automation cell, it serves as an electromechanical actuator that provides the precision positioning and velocity control required for repeatable production tasks.

The unit relies on natural convection for heat removal, so it must be installed where ambient airflow can dissipate heat effectively. A housing sealed to IP65 prevents dust ingress and water jets from reaching internal windings, allowing direct mounting outside of control cabinets. Position feedback is generated by an optical measuring system that offers 128 signal periods per shaft revolution, and this pattern is processed through the Hiperface interface so the drive obtains absolute rotor position after power-on. Because the encoder is single-turn, one mechanical rotation resets the absolute count, a feature that simplifies homing on short-stroke axes.

The motor has a shaft with a keyway, enabling positive torque transfer to pulleys or gear couplings without relying on friction fits. An electrically released holding brake supplies 70 Nm of static torque, letting vertical axes remain parked during power interruptions. The class 155 insulation system supports continuous copper temperatures within the intended operating range, while an ambient temperature range of 0–40 °C keeps thermal rise within design limits. Power wiring exits on the B-side of the frame, and winding code 0450 indicates the electrical resistance and inductance used with compatible MSK drive amplifiers.
