Product Description:

The MSK050B-0300-NN-M1-UG0-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It works as an electromechanical actuator that converts drive current from IndraDrive controllers into precise rotational motion. This makes it suitable for positioning, conveying, and metering tasks across automated production cells. It is intended for applications that need stable speed control and accurate position tracking during repeated automatic cycles.

Its cooling relies on natural convection, so heat leaves the housing through surface radiation and ambient airflow without auxiliary fans or liquid circuits. The encoder connector is rotatable through 240°, allowing the cable exit to match cabinet layouts while preserving the seal. Feedback is transferred over the Hiperface protocol, which combines absolute position data and parameter storage on two differential signal pairs. The integrated scale delivers 128 signal periods, enabling fine interpolation for smooth velocity loops. An optical sensing method reads the coded disk, helping maintain feedback accuracy across temperature changes without magnetic drift.

The feedback system uses a multiturn absolute function, so the drive can power up with shaft position information over several revolutions and avoid homing cycles. The motor is supplied without a holding brake, so external clamping or servo torque must maintain position when power is removed. The motor has size 050 with length class B, which gives it a compact body for light-duty axes and pick-and-place heads. Winding code 0300 matches the electrical characteristics expected by compatible IndraDrive amplifiers. A plain shaft and a standard housing design provide a direct mechanical interface for couplings, timing pulleys, or gearboxes.
