Product Description:
The MSK071C-0450-NN-M1-UG0-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. In automated machinery, it receives controlled current from a drive and converts that energy into precise rotary motion for indexing tables, pick-and-place arms, and feeder axes. The motor’s electromagnetic design supports fast response during repeated acceleration and deceleration. Closed-loop position feedback is handled by an integrated optical encoder. This type of motor is commonly paired with servo drives that regulate current, speed, and position in real time, helping the axis follow programmed motion profiles under changing load conditions.
The unit relies on natural convection for heat dissipation, so airflow around the housing must remain unobstructed to keep winding temperatures within limits. Position data are provided by a feedback assembly that combines the Hiperface protocol with an optical scanning system, allowing absolute position transmission and digital parameter storage inside the encoder. The measuring disk provides 128 signal periods, which gives the controller fine angular resolution after interpolation by the drive. Because the encoder is multiturn absolute, the motor can report shaft position across multiple revolutions without requiring homing after power cycles. This feedback arrangement helps the axis retain position information during restart after an interruption.
The electrical interface uses a 240° rotatable connector, which helps route cables in cabinets or machine frames with limited clearance. Torque is delivered through a plain shaft, allowing couplings or pulleys to be installed without keyway alignment. The motor has motor size 071 and winding code 0450, together with motor length C and a standard design housing. It is supplied without a holding brake, so load retention must be provided by the drive or by the mechanical transmission when the axis is at rest. That arrangement suits systems that use gearing or drive-generated torque to maintain position at standstill.
