Product Description:

The MSK070D-0300-NN-S3-BG0-NNAN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is intended for industrial automation axes that require controlled torque and repeatable positioning, allowing a drive controller to translate electrical setpoints into precise rotary motion for pick-and-place, packaging, or printing equipment. Its synchronous design supports stable speed regulation and accurate positioning during frequent start-stop cycles, making it suitable for machinery that depends on responsive motion and consistent tracking.

The motor is cooled by natural convection, so the housing dissipates heat without forced airflow or external liquid circuits. Its stator uses winding code 0300, and the frame is size 070 with length code D, which gives the motor a compact footprint while still supporting useful torque for mid-size axes. Position feedback is delivered through a Hiperface interface from a capacitive single-turn encoder. The encoder provides 16 signal periods per mechanical revolution, allowing the drive to manage commutation and position control accurately within one turn. The rotor and flange use a reduced run-out design that helps limit radial deviation at the coupling point. An IP65 enclosure protects the motor against dust ingress and low-pressure water jets, so it can be mounted on open machine frames.

Mechanical connection to the driven load is made by a plain shaft, which supports backlash-free clamp or shrink couplings. The power connector is oriented on side B, which can simplify cable routing where space is limited around the motor body or machine frame. The servo motor is supplied without a holding brake, so vertical or suspended loads need external locking or drive-produced holding torque when power is removed. Continuous operation is specified for ambient temperatures of 0 to 40 °C, and the winding insulation uses Class 155 thermal endurance to withstand sustained internal heating during normal duty.
