Product Description:

The MSK050B-0300-NN-M3-UP1-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat and assigned to the MSK IndraDyn S Synchronous Motors series. It converts electrical energy into tightly regulated rotary motion, allowing automation controllers to index tooling, feed material, or coordinate multiple axes in production equipment. As part of an integrated drive chain, this motor serves in applications that require accurate velocity and position control. When paired with a compatible drive, it can support repeatable motion in indexing, transfer, and synchronized axis tasks.

Within the standard mechanical design, the motor enclosure relies on natural convection for heat removal, so no external blower or liquid circuit is required. Its housing is sealed to IP65, which helps prevent dust ingress and water jets from reaching the internal windings during washdown cycles. Signal integration is handled through a rotatable connector that can be turned through 240°, making cable routing more flexible in confined machine spaces. The feedback channel uses the Hiperface interface and delivers position data at a resolution of 16 signal periods, supporting responsive servo control. Electrical behavior follows winding code 0300, which provides resistance and inductance values suited to mid-voltage IndraDrive controllers.

Position reference is generated by a capacitive encoder built as a multi-turn absolute sensor, so the drive retains shaft angle information across power cycles without an external battery. An electrically released holding brake rated at 6 Nm secures the load during idle states or emergency stops, which is useful when the axis must remain in place after drive power is removed. Mechanical coupling is provided through a keyed shaft, and the B-length size-050 frame fits compact gearboxes where space is limited. Continuous operation is permitted up to 40 °C, and class 155 insulation supports the associated winding temperatures during normal service.
