Product Description:

Bosch Rexroth Indramat manufactures the MSK100A-0300-NN-M1-BG0-NNNN within the MSK IndraDyn S Synchronous Motors series. This synchronous servomotor converts electrical input into precisely regulated rotary output, enabling accurate speed and position control on packaging machines, assembly robots, and processing lines. Compact dimensions and high torque density allow the unit to deliver dynamic motion without adding significant mass to the moving axis.

The motor releases heat through natural convection, eliminating the need for forced-air or liquid cooling and simplifying enclosure design. Position feedback is supplied by an optical encoder that uses the Hiperface interface; this bidirectional channel carries both power and absolute position data. The sensor resolves rotation into 128 signal periods, and because it is a multiturn absolute device, the controller receives the exact shaft angle and revolution count after power is restored. The encoder’s optical scanning principle increases immunity to electrical noise, and winding code 0300 indicates an electromagnetic layout suited to general-purpose duty cycles. For safety-related stops, the unit ships without a holding brake, so external braking or static friction torque must be provided where required. A Class 155 insulation system supports winding temperatures associated with dynamic servo operation.

The frame corresponds to Motor Size 100, and the A length maintains a balanced ratio between torque output and mass for mid-range servo axes. Power leads exit on the B-side of the housing so cabinet wiring can be routed away from moving machine parts. A plain shaft allows flexible coupling options and features factory grinding for minimal runout. The housing is rated IP65, sealing the interior against dust ingress and low-pressure water jets encountered on production floors. Stable operation is specified for ambient temperatures from 0–40 °C, and the standard design tolerates typical plant humidity without additional coatings.
