Product Description:

The MSK101E-0300-NN-M3-BP0-NNNN is a synchronous servo motor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. The motor provides rotary actuation for positioning, interpolated motion, and speed control tasks inside CNC machines and automated production cells. By pairing with Rexroth drive controllers, the unit converts commanded current into mechanical torque with high-resolution feedback, enabling tightly controlled axis performance in industrial automation. It also fits directly into the IndraDyn S drive platform for coordinated motion applications.

Thermal management relies on natural convection, so the housing dissipates heat without external fans or liquid circuits. The integrated encoder uses the Hiperface serial interface, and its capacitive scanning method provides rugged signal generation across 16 signal periods per mechanical revolution for commutation data. Because the encoder is a multi-turn absolute type, the controller retains shaft position information after power loss, eliminating homing cycles. The motor is sealed to IP65, so dust ingress is prevented and water jets do not affect operation. The motor follows winding code 0300 and length class E, and the power connector is located on the B-side to suit common cable routing. It is supplied without a holding brake, so external braking hardware is needed when static torque retention is required.

The drive end uses a shaft with a keyway, providing straightforward coupling to pulleys or gear sets while helping prevent slippage under peak torque. The motor can operate in ambient temperatures from 0 to 40 °C, which helps preserve magnet strength and lubricant viscosity. Electrical insulation conforms to class 155, giving headroom for winding temperatures encountered during cyclic overloads. With frame designation 101, the stator diameter and mounting pattern match other motors in the series.
