Product Description:

The MSK101C-0300-NN-S1-BP0-NNNN synchronous servomotor is manufactured by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. In an automation cell, this motor works with a Rexroth drive controller to deliver regulated torque and speed for repeatable motion on feed axes, pick-and-place arms, and indexing tables. Its 101 frame size and C length balance torque density with installation space, which helps when the machine layout must support compact servo placement without sacrificing dynamic response. The motor is intended for applications that need controlled acceleration, stable running speed, and accurate stopping under changing load conditions.

Cooling of the stator windings relies on natural convection, so enclosure fins dissipate heat without external fans or liquid circuits. Motor feedback is exchanged through a Hiperface encoder link that carries both power and digital position data over two conductors. Inside the scanning head, the code disc generates 128 signal periods per revolution, giving the drive controller enough resolution for stable speed control and position monitoring. Measurement is based on an optical principle, which avoids magnetic drift and supports consistent signal quality across temperature changes. The feedback module is a single-turn design, so it stores absolute shaft position within one mechanical revolution and allows the control system to recover position information quickly after a power interruption. The housing meets IP65, which helps protect internal parts from dust and directed water when the motor is mounted close to the machine process.

The motor is supplied without a holding brake, so static load retention must be managed by external clamping or drive torque. That arrangement is suitable where the axis does not need a mechanical holding function after shutdown. It may operate in ambient temperatures from 0–40 °C, a range coordinated with the class 155 insulation system and the 0300 winding to limit thermal stress during normal service. Mechanical coupling is via a shaft with keyway, and the power connector is oriented on the B-side to simplify cable routing in gantries, transfer units, and robotic wrists.
