Product Description:

The MSK101E-0200-NN-S1-BP0-NNNN is an IndraDyn S synchronous servomotor from Bosch Rexroth Indramat's MSK IndraDyn S Synchronous Motors series. As a torque-dense rotary actuator, it is installed in industrial automation lines where closed-loop velocity and position control are required. The motor is a standard design unit intended for mounting in cabinets or on machinery frames and for use with a compatible Rexroth drive controller in coordinated multi-axis motion.

This model relies on natural convection to discharge heat, so its continuous output ratings are maintained without forced airflow or liquid channels. Rotor position is reported through a Hiperface feedback interface that carries absolute and incremental data to the drive over two shielded conductors. The transducer inside the motor is an optical encoder manufactured with photolithographic gratings. It divides one mechanical revolution into 128 signal periods, allowing the drive to interpolate fine resolution for smooth commutation. Because the encoder is a single-turn device, the absolute angle resets after every 360°, making it suitable for applications where multi-turn tracking is handled by the controller rather than the motor. The stator lamination stack uses the E length code, giving the winding a thermal mass that complements its cooling method. There is no holding brake, so mechanical locking or drive torque must secure the load during power loss.

Electrical characteristics follow winding code 0200, which sets the resistance and inductance values expected by the matching drive. Power and protective earth conductors connect on the B-side, simplifying cable routing when several axes are arranged in series. The output shaft uses a shaft with a keyway, providing a positive drive interface for pulleys and couplings without relying only on clamping friction. A frame size of 101 mm sets the flange pattern and rotor diameter, allowing the motor to fit machine layouts that use this mechanical envelope.
