Product Description:

The MSK050B-0450-NN-S1-UP1-NNNN servomotor is built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, it provides precise torque and position control for packaging lines, pick-and-place axes, and other motion tasks in industrial automation cells. Feedback is transmitted through a Hiperface serial interface, so the drive receives commutation data and absolute position information through one integrated feedback channel. This arrangement supports synchronized indexing, repeatable point-to-point moves, and stable speed regulation on compact machinery where cable space and response time both matter.

The motor housing follows a standard design with an IP65 enclosure, so dust and low-pressure water jets do not affect the internal windings. Heat is removed through natural convection, eliminating the need for external fans and helping the motor fit installations where airflow hardware would add complexity. The integrated holding brake is electrically released and produces 6 Nm of static torque to secure vertical loads when power is off. Mechanical output is delivered through a shaft with a keyway, and the 050 frame size with B length gives the unit a compact footprint while maintaining useful continuous torque capacity. Service cabling is simplified by a rotatable encoder connector that can be swung over a 240° arc, reducing bend stress in tight machine layouts. The encoder uses optical scanning and resolves motor position into 128 signal periods per revolution to support fine loop control within the drive.

The feedback device has a single-turn arrangement, so it reports one absolute position value for each mechanical revolution. This layout suits short-stroke axes that remain within one turn and allows the drive to recover shaft position quickly after power cycling without relying on a separate reference pass in many applications. Class 155 insulation supports continuous operation in ambient temperatures from 0 to 40 °C, and winding code 0450 identifies the electrical characteristics selected for this frame.
