Product Description:

The MSK071D-0300-NN-M1-BG0-NNAN is a synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop industrial automation where precise torque, speed, and positioning are necessary. By interfacing with a compatible drive, the motor supplies smooth rotary motion to conveyors, pick-and-place heads, or packaging spindles while maintaining synchronization with the master controller.

Thermal regulation relies on natural convection, so airflow around the housing is required instead of forced cooling. The assembly carries an IP65 protection rating, sealing the stator against dust ingress and water jets for typical machine-side mounting. A plain shaft with reduced run-out minimizes radial error during coupling to precision gearboxes. Feedback and power terminations are separated; the power connector is located on the B-side to simplify cable routing, and digital feedback is transmitted through a Hiperface interface that carries position and parameter data over a single hybrid cable. The measuring system uses an optical scanner, and the mechanical package follows motor size 071 with length code D, yielding a balanced ratio between continuous torque and overall envelope. Because the unit ships without a holding brake, external clamping devices must secure vertical loads when power is removed.

The position encoder delivers 128 signal periods per mechanical revolution, and its multi-turn absolute capability keeps track of shaft angle across 4096 turns without battery backup, supporting homing-free starts after power cycles. The specified ambient range of 0 to 40 °C helps maintain thermal stability when the winding insulation is operated within Class 155, so continuous current does not accelerate aging. Winding code 0300 tailors the stator resistance and inductance for drives that expect the associated torque-speed curve. Operation within those ambient and insulation limits supports repetitive indexing and moderate-load contouring.
