Product Description:

The MSK070D-0450-NN-M2-UG0-RNNN is a synchronous servomotor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. It converts drive controller commands into precise rotary motion for automated packaging axes, pick-and-place arms, and forming stations. With its 070 frame and D-length housing, the unit fits installations that need high torque density and steady speed regulation while avoiding external ventilation hardware. This type of motor is suited to axes that must accelerate cleanly, hold commanded speed under changing load, and repeat short motion cycles without losing positioning stability.

Its cooling relies on natural convection, so heat is removed through the stator surface without fans or liquid circuits. The rotor and stator use an increased concentricity design to reduce runout and limit vibration at the driven load. Size code 070 sets the flange and mounting dimensions, while the 0450 winding code identifies the electrical winding used in this motor. A plain shaft without a keyway simplifies coupling to backlash-free clamping hubs and reduces the need for keyed shaft hardware. The motor is supplied without a holding brake, so static load retention must come from external locking or drive torque when the axis is stopped.

The feedback connector is rotatable through 240°, allowing the cable outlet to align with available routing space. Inside the housing, an optical feedback system uses the EnDat2.1 serial interface. The measuring disc provides 2048 signal periods per revolution, and the coded track stores multiturn absolute position data so the controller can identify shaft angle after power is restored. This arrangement supports accurate commutation at startup and stable position tracking during continuous motion. Optical scanning helps avoid magnetic offset effects, and the encoder electronics remain thermally coupled to the frame because the motor has no internal fan.
