Product Description:

The MSK101E-0300-NN-M1-AP3-NNNN is a synchronous servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Within a motion system, it converts drive current into precise rotational torque and serves as the primary mover for indexing tables, gantry axes, and other closed-loop assemblies. Permanent-magnet excitation, paired with an integrated high-resolution feedback device, gives the controller tight authority over position and speed, making this motor suitable for industrial automation that requires repeatable trajectories and fast response. It is intended for axes that must accelerate, decelerate, and settle accurately under changing load conditions.

Cooled by natural convection, the unit operates without external fans, which helps keep enclosed installations simpler and quieter. The housing carries an IP65 ingress rating that shields the stator, bearings, and windings from dust and water jets during washdown. Rotor position is delivered over a Hiperface serial channel, and the optical reader resolves the pole pitch into 128 signal periods, providing fine commutation data for IndraDrive amplifiers matched to winding code 0300. This feedback arrangement supports smooth low-speed operation and stable response during rapid changes in commanded motion. The 120 Nm electrically released holding brake provides static torque for load retention, and the power connector on the A-side lets motor, brake, and encoder cables run parallel along one face of the machine.

The feedback assembly is a multi-turn absolute device, so the controller recovers exact shaft angle after power is restored without a homing cycle. A shaft with keyway simplifies coupler alignment and helps prevent slippage under peak torque, which is useful in direct-drive connections and gearbox inputs. Continuous duty is allowed in ambient air between 0–40 °C, and the windings carry insulation class 155, which supports elevated internal temperatures without degrading varnish or magnet adhesive. Frame size 101 with the E length gives the motor a high-torque format that fits standard MSK mounting flanges.
