Product Description:

The MSK050B-0450-NN-M1-UP1-NNNN is a synchronous servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It provides regulated rotary motion for positioning and speed control in industrial automation equipment such as pick-and-place axes, conveyors, and packaging stations. In service, the motor converts controlled electrical input into precise shaft rotation for indexing, transfer, and repeatable axis movement. When paired with a compatible drive, it supports closed-loop operation so commanded motion can be corrected during acceleration, steady running, and stopping.

For thermal management, the motor relies on natural convection, so surrounding airflow must remain unobstructed to remove heat from the stator. The housing carries an IP65 rating that blocks dust and low-pressure water jets, allowing installation on exposed machine frames. Winding code 0450 is assigned to this motor, and the 050 frame size with B length gives a compact magnetic section suited to moderate torque output. Command and feedback signals pass through the Hiperface interface, where an optical encoder provides 128 signal periods and multi-turn absolute position retention after power loss. A spring-applied, electrically released brake provides 6 Nm of holding torque to secure vertical or suspended loads when the drive is disabled.

The feedback plug uses a rotatable, 240° connector, so cabling can leave the housing in several directions without excessive bend stress. Continuous operation is permitted in ambient temperatures of 0–40 °C, which suits standard factory conditions. Torque is transmitted through a shaft with keyway for secure coupling to pulleys or gearboxes during acceleration and deceleration. Coil insulation meets class 155, supporting the motor's thermal load during regular duty. Flexible cable exit routing is useful on packaging and handling machinery where motors are mounted close to guards, plates, and other nearby components.
