Product Description:

The MSK040B-0600-NN-M1-UP1-NSNN is an IndraDyn S synchronous servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. This motor is used on automated axes that require closed-loop speed and position control, receiving power from a drive controller and converting it into rotary torque for pick-and-place units, metal-cutting spindles, or packaging machinery. Its compact servo design supports precise motion tasks where fast response and repeatable positioning are required throughout normal machine operation. It is intended for coordinated motion systems that depend on accurate acceleration, deceleration, and repeatable stopping behavior.

Heat is removed by natural convection, allowing installation without forced airflow. Position feedback is generated by an optical encoder that resolves the shaft into 128 signal periods, and the connector can rotate 240° to simplify wiring inside tight machine frames. The assembly has a protection rating of IP65, so dust ingress is prevented and low-pressure water jets can be tolerated. Continuous operation is permitted from 0 to 40 °C; outside this range, derating or external cooling is necessary. Torque is transmitted through a shaft with a keyway, which supports positive coupling to the driven load. The motor has size 040 laminations, frame length B, and winding code 0600, and the selected design can be used in standard or explosion-protected installations.

An electrically released brake supplies 4 Nm of holding torque when power is removed, which is useful on vertical axes and other loads that must remain in position at standstill. Class 155 insulation supports elevated winding temperatures during continuous servo operation. Digital communication with the drive takes place through Hiperface, enabling absolute position data from the encoder's multi-turn absolute counting system. The brake coil is powered from the drive output, so a separate brake supply is not typically required. This feedback arrangement lets the control loop track shaft position after power-up and supports stable motion during speed changes and indexing moves. Optical sensing also helps the drive maintain accurate commutation across repeated start-stop cycles.
