Product Description:

The MSK101C-0300-NN-S1-BP2-NNNN is a synchronous servo motor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. In automated production cells, it converts drive current into controlled torque and speed for positioning tables, press axes, or gantry drives. Its integrated feedback loop supplies precise motion data to the associated IndraDrive controller for closed-loop regulation, and its mechanical and electrical characteristics suit mid-frame automation tasks that require repeatable acceleration.

The motor carries the Cooling FN designation, and its thermal mode is Natural convection, so enclosure fins radiate heat without auxiliary blowers. A housing sealed to IP65 resists dust ingress and low-pressure water jets, and the mechanical layout follows the standard design. Power lands on the B-side connector, and winding code 0300 matches the stator to medium-range inverters. Position sensing relies on a Hiperface optical encoder that produces 128 signal periods per revolution in a single-turn format, providing one-turn absolute values as soon as the axis powers up. Length code C indicates the stator stack, balancing inertia and torque, while an electrically released brake locks the rotor with 70 Nm when power is removed to help prevent vertical loads from drifting.

Dimensional code 101 identifies the frame size, giving the motor a substantial shaft diameter suited to mid-power machinery. The unit can operate continuously within an ambient range of 0–40 °C, and temperatures above that range reduce the allowable current. A shaft with keyway provides a keyed coupling that helps prevent rotational slip under cyclic loads. Insulation class 155 permits elevated winding temperatures and supports duty cycles that remain within the motor's thermal capability.
