Product Description:

The MSK100D-0300-NN-M2-BG0-RNNN synchronous servo motor is manufactured by Bosch Rexroth Indramat and is part of the MSK IndraDyn S Synchronous Motors series. The unit converts regulated electrical power into rotary mechanical motion for CNC stations, pick-and-place robots, and other closed-loop axes that require stable speed and repeatable positioning in compact installations. It actuates loads through a balanced rotor and feedback encoder, serving as the electromechanical element of an IndraDrive axis.

This motor uses natural convection for cooling, so heat produced in the stator is dissipated directly to ambient air and cabinet airflow requirements stay minimal. The winding package uses code 0300, which corresponds to electrical characteristics suited to medium-torque and medium-speed duty cycles. Position and velocity feedback are transmitted over the EnDat2.1 serial interface, supplying absolute data to the drive with cyclic redundancy monitoring. Inside the encoder, the scale provides 2048 signal periods, allowing fine interpolation for high-resolution motion control. The motor is supplied without a holding brake, so applications that require power-off holding torque must use an external brake or another holding method.

The feedback element is a Multiturn Absolute device that records multiple shaft revolutions, and its sensing principle is Optical, which avoids cumulative magnetic offset errors. The motor has a Plain shaft, which simplifies coupling to gearboxes or pulleys. The housing uses motor size 100 with a D-length stator section, giving higher active iron volume without increasing the frame diameter. Power cabling exits on the B-side to ease routing in line-mounted machines. The internal rotor machining uses an increased concentricity design that helps reduce runout during closed-loop operation.
