Product Description:

The MSK100C-0450-NN-M2-LP0-RNNN is a rotary servo motor manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. Designed for closed-loop positioning, it pairs with IndraDrive controllers to move tooling, conveyor sections, and robotic joints with consistent accuracy. Internal Hall signals and sinusoidal encoder signals allow the control system to monitor speed and absolute rotor angle during operation. Its synchronous design supports precise response during acceleration, deceleration, and steady-speed holding in automated axes. This makes the motor suitable for coordinated multi-axis tasks in packaging, printing, and material-handling equipment where repeatable motion is required across changing loads.

Thermal management is handled through natural convection, so the mounting surface must carry away heat without forced airflow. Feedback wiring uses the EnDat2.1 serial interface, which transmits position data derived from 2048 signal periods per revolution. The enclosure has an IP65 rating to block dust ingress and resist water jets, and class 155 insulation permits winding temperatures up to 155 °C during normal inverter duty. Increased concentricity in the mechanical design helps reduce radial runout during rotation. The left-side power connector also simplifies cable routing where installation space is limited.

The motor uses size 100 stator laminations and length code C, which fit the overall frame of this model. Position reporting remains available after power loss because the encoder is a multi-turn absolute device that counts shaft revolutions internally. Operation is specified from 0 to 40 °C, so it can run in normal plant conditions without temperature-related derating. A shaft with keyway provides positive drive coupling to pulleys or gear sets, and winding code 0450 identifies the motor's electrical configuration within the series. Because the motor does not include an integrated brake, any required holding force must come from external hardware or drive-controlled torque.
