Product Description:

The MSK070E-0450-NN-M1-UG0-NNNN is a synchronous servo motor built by Bosch Rexroth Indramat and assigned to the MSK IndraDyn S Synchronous Motors series. It provides closed-loop rotary actuation for industrial automation cells, allowing drive controllers to command accurate speed and position. As an IndraDyn S unit, it is engineered for direct coupling to load-side mechanics, reducing backlash and increasing stiffness in packaging, handling, and metal-forming equipment. Its 070 frame size and E-length stator place it in the mid-range power class required for multi-axis systems.

Thermal management relies on natural convection, so the motor sheds heat through its housing fins without forced airflow; this influences permissible load cycles and cabinet layout. The internal measuring system uses an optical encoder that communicates through the Hiperface protocol, enabling simultaneous position and motor-temperature data on a two-wire link. Position granularity reaches 128 signal periods per mechanical revolution, and the track is built as a multiturn absolute device, preserving count after power loss for homing-free restarts. Motion safety components must be external because the unit ships without a holding brake. The standard design designation confirms that mechanical tolerances, paint, and connector placement follow the common MSK pattern. Motor length code E indicates the active core depth and the achievable continuous torque curve.

The feedback plug is a rotatable 240° encoder connector, so cable routing can be turned to match tight machine envelopes without bending strain. Drive shafts are delivered as a plain shaft, allowing clamp or collet couplings where torque transmission must remain concentric. System sizing is simplified because the frame is identified as 070, making its flange pattern compatible with other mid-size IndraDyn machines. Winding code 0450 identifies the copper fill and pole configuration, allowing the motor to be matched with inverter current ratings that use its thermal capacity without excessive oversizing.
