Product Description:
The MSK100C-0200-NN-M2-BG2-RNNN is a synchronous servo motor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop positioning and velocity control on medium-power machine axes where compact dimensions and high dynamic stiffness are required. The motor’s length-C housing and size-100 stator core place it in an intermediate torque class without the footprint of larger MSK units. This makes it suitable for pick-and-place modules, form-fill-seal stations, and Cartesian gantries that require accurate motion and repeatable axis response.
Heat dissipation is handled through natural convection, so only ambient airflow is needed to keep the windings within their thermal limits. Rotor position feedback is generated by an optical encoder that communicates through the EnDat2.1 interface, and its sampling grid contains 2048 signal periods for high-resolution interpolation in the drive. The encoder is a multi-turn absolute type, which preserves revolution count information and reduces the need for homing after power is restored. For load holding on vertical or suspended axes, an electrically released brake is fitted with a static capacity of 70 Nm, allowing the shaft to remain locked when control power is removed.
An enclosure rating of IP65 protects the stator against dust ingress and low-pressure water jets, and the motor uses a plain shaft to interface with couplings or belt pulleys without keyway stress concentrations. Power leads exit on the B-side, which can simplify routing where the opposite face is obstructed by nearby machine components. Reliable operation is specified between 0 – 40 °C ambient, a range supported by insulation class 155 and the 0200 winding set. The increased concentricity design helps minimize radial runout during rotation, which supports smooth mechanical coupling and stable motion quality.
