Product Description:

The MSK101E-0300-NN-M1-BG2-NNNN is a rotary servomotor from the MSK IndraDyn S Synchronous Motors series produced by Bosch Rexroth Indramat. It converts drive current into precise torque for positioning and velocity control in automated machinery such as gantry axes, packaging stations, and machine-tool spindles. In closed-loop service, the motor works with a compatible drive to maintain commanded speed and position while responding quickly to load changes. This makes it suitable for axes that require repeatable motion, smooth acceleration, and stable operation during frequent start-stop cycles.

This model uses natural convection for cooling, so airflow around the housing must remain unobstructed. The motor has a size of 101 and a compact length code E, which keeps the package short while preserving the active magnetic section needed for servo duty. The stator uses winding code 0300, which sets the electrical values expected by compatible drive power stages. A rear-mounted B-side power connector helps separate high-current leads from the feedback cable and can simplify routing where the rear of the motor faces the cable run. Position feedback is transmitted through the Hiperface serial interface, which carries absolute position data to the drive controller without extra wiring.

Rotor position is resolved into 128 signal periods per mechanical turn, and the encoder has multiturn absolute capability so the controller can retain shaft position across power cycles. An electrically released brake supplies 70 Nm of holding torque to secure vertical or suspended loads when motion is stopped. The motor is fitted with a plain shaft, which supports accurate hub alignment and avoids the stress concentrations associated with keyed couplings. The standard design uses optical scanning for position feedback.
