Product Description:

The MSK101D-0300-NN-M1-AK0-NN02 is an AC servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. The unit serves as a drive element in automated machinery where closed-loop speed and position control are required. It delivers precise torque from a compact frame, allowing machine tools, packaging stations, and handling axes to follow programmed motion profiles without mechanical backlash.

This motor relies on natural convection for thermal dissipation, so mounting space must permit vertical airflow around the housing. Position feedback is routed through a Hiperface interface that carries both incremental and absolute data from the optical encoder. The feedback device subdivides one mechanical revolution into 128 signal periods, enabling fine interpolation by the drive controller. Because the scanner is a multiturn absolute type, it can track up to 4096 shaft revolutions without external batteries. All components sit behind a sealed housing rated at IP65, which prevents dust intrusion and protects internal parts against low-pressure water jets during washdown cleaning.

The electrical design follows winding code 0300, a configuration that matches the torque constant and resistance values expected by compatible IndraDrive servo amplifiers. Insulation system class 155 supports elevated winding temperatures before the thermal sensors respond. Safe operation is specified for ambient temperatures between 0–40 °C; outside this range, derating or additional cooling is required. The stator uses motor size 101 with length D, giving a balanced ratio between peak torque and inertia. Power and feedback connections are routed on the A-side of the motor, and the shaft is supplied without a holding brake, so external mechanical locking must be provided when power is removed. The optical encoder uses noncontact sensing, which avoids mechanical wear in the feedback system during normal operation.
