Product Description:

The MSK050C-0300-NN-S1-BG0-NNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Designed for precision positioning and speed control, it couples directly to linear tables, rotary actuators, and packaging modules where constant accuracy is required. The motor operates as a torque-controlled actuator with IndraDrive converters, delivering rapid dynamic response while maintaining repeatable motion profiles across automated production lines.

Thermal management relies on natural convection, so heat leaves the stator through finned aluminum surfaces without additional fans or liquid circuits. Rotor position is relayed over the Hiperface interface by an optical scanner that produces 128 signal periods per revolution. Because the sensing method is optical, the feedback provides precise position data for interpolation inside the drive controller. The motor has an IP65 rating that helps protect internal components from dust and low-pressure water jets. Continuous duty is permitted in ambient temperatures from 0–40 °C, and the molded power connector is located on the B-side so cable routing can stay clear of the load axis.

A plain shaft simplifies coupling to gearheads or belt pulleys, and the stator windings use class 155 insulation to withstand elevated copper temperatures during cyclic acceleration. The motor uses winding code 0300, which matches the electrical characteristics expected by standard IndraDrive supply modules. Its size 050 frame and C-length stack provide moderate inertia for mid-range tooling, while the standard housing design supports common OEM mounting layouts. The motor is supplied without a holding brake, so vertical axes require an external clamp, and the single-turn encoder helps reduce homing time after power-up.
