Product Description:

The MSK040B-0600-NN-M1-UG1-NSNN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is intended for precise position and speed control on automated tooling, handling equipment, and packaging lines where the drive must respond quickly to changing commands. The motor includes a multi-turn absolute optical encoder, so the control system can retain shaft position information through power cycles. It also has an electrically released holding brake that supports static load retention when the axis is stopped.

This model uses natural convection for cooling, so the housing needs unobstructed airflow instead of fan-assisted ventilation. A protection rating of IP65 helps keep dust and low-pressure water jets away from internal components, which supports mounting close to process equipment. Command and feedback signals pass through the Hiperface interface, and the rotatable 240° connector helps route cables in confined machine layouts. The electrically released brake provides 4 Nm of holding torque, which helps keep vertical or indexing axes in place when drive power is removed. Continuous operation is permitted in ambient temperatures from 0 to 40 °C, and operation outside that range requires additional cooling or derating.

The encoder delivers 128 signal periods per mechanical revolution, and its multi-turn function preserves absolute shaft position after shutdown. The motor uses frame size 040 with length code B, giving it a compact housing with a plain shaft that transmits torque without key slots. Winding code 0600 matches the electrical characteristics expected by compatible IndraDrive controllers, helping the drive regulate current and motor response correctly. Insulation class 155 allows elevated winding temperatures during intermittent overload conditions.
