Product Description:

The MSK050B-0600-NN-M1-UP1-NSNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It converts drive controller commands into controlled shaft torque and position for compact industrial axes that require accurate rotary motion. Typical uses include pick-and-place stations, feeders, and light conveyor drives, where a compact housing and integrated feedback support responsive motion without adding unnecessary installation bulk. Because torque production and position feedback are combined in one assembly, the motor fits machine modules that need precise starts, stops, and repeated indexing. The design suits light servo axes that need repeatable positioning in compact machine layouts.

Cooling is handled through natural convection, so the housing releases heat without forced air or liquid circuits and the installation should leave space for free airflow around the frame. The enclosure has an IP65 rating, which helps keep out dust and low-pressure water jets when the motor is mounted directly on machinery. This sealing allows direct machine mounting in areas with dust or incidental spray. Feedback is transmitted through the Hiperface interface with 128 signal periods, giving the drive fine position information during interpolation. The encoder plug rotates through 240 degrees for flexible cable routing, and an electrically released brake provides 6 Nm of holding torque when power is removed.

The motor uses a multi-turn absolute encoder, so the drive can retain shaft position over multiple revolutions after power cycles and return to operation without a homing routine. Continuous operation is permitted from 0 to 40 °C, which matches common indoor production conditions. Mechanical power is delivered through a shaft with keyway for secure coupling to pulleys or gear wheels, and insulation class 155 supports elevated winding temperatures during dynamic duty. The B length code, 050 frame size, and 0600 winding package keep the motor compact for light servo applications. The standard plus explosion-protected option allows the same external outline to be used in nonhazardous or Class I Division 2 locations.
