Product Description:

The MSK100B-0400-NN-M1-AP0-NNNN is a synchronous servo motor from the MSK IndraDyn S Synchronous Motors series produced by Bosch Rexroth Indramat. It converts commanded electrical power into precise rotary motion for axis control in industrial automation systems such as packaging stations, metal-cutting centers, and material-handling gantries. By integrating feedback electronics with a permanent-magnet rotor, the unit supports closed-loop speed and position regulation without an external encoder. This arrangement allows the connected drive to track rotor movement continuously and correct load-related deviations during acceleration, deceleration, and steady operation. That makes the motor suitable for synchronized axes that need repeatable starts, stops, and short positioning moves.

The motor relies on natural convection, so heat leaves the stator housing through ambient airflow without fans or liquid lines. Rotor position is reported through a Hiperface interface that carries serial feedback data to the drive. The encoder provides 128 signal periods per mechanical revolution and uses an optical scanning method, which helps resist magnetic interference. A multi-turn absolute encoder architecture stores position across multiple revolutions, so the drive can retain position information after power is removed. The motor is supplied without a holding brake, so any required holding force must come from external braking hardware or the driven mechanism.

Mechanical coupling is handled through a shaft with a keyway, allowing positive torque transfer to pulleys or couplings while preserving axial alignment. This shaft style is useful where a keyed connection is preferred over a clamp-only connection. The motor uses winding code 0400 and a stack identified as length code B, which balances continuous torque capability with installation depth. Field wiring is simplified because the power leads exit on the motor’s A-side, leaving the opposite face clear for the feedback connection. This cable layout can help in enclosures where bend radius, connector access, and motor clearance are limited.
