Product Description:
The MSK101C-0450-NN-M2-AG2-RNNN is a synchronous servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Within an automation cell, this motor acts as the direct drive element, converting the drive amplifier’s electrical output into precise rotary motion for tooling stations, gantry axes, or packaging spindles. Its construction follows the IndraDyn standard, allowing straightforward pairing with Rexroth drive controllers for position-controlled operation.
This model uses frame size 101 in the MSK lineup, and the stack length code C increases active iron to raise continuous torque without enlarging the mounting pattern. Heat is removed through natural convection; the Cooling FN designation only indicates the need for unobstructed airflow rather than external blowers. The motor employs an optical multi-turn absolute encoder that communicates through the EnDat2.1 interface, delivering 2048 signal periods per revolution so the drive can detect position changes with high angular granularity. A winding code of 0450 aligns resistance and inductance with MSK family drive modules, while the increased concentricity design minimizes radial runout for applications that demand uniform velocity. All power conductors exit on the A-side housing, and a plain shaft simplifies coupling to keyed or shrink-fit hubs.
An electrically released holding brake supplies 70 Nm of static torque, allowing vertical axes to remain stationary when power is removed. The housing is sealed to IP65, blocking dust ingress and water jets so the motor can sit outside the control cabinet. Safe operation is specified from 0 °C to 40 °C; staying within this window keeps winding temperatures below insulation class 155 limits. The plain shaft and precise concentricity reduce vibration transfer to adjacent machine elements, and the feedback system retains absolute position after power cycling.
