Product Description:

The MSK050B-0450-NN-S3-UG0-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. The unit uses a plain shaft that mates directly with couplings or pulleys, and its 050 frame size provides a compact footprint for axis drives on packaging machinery and pick-and-place gantries. The motor uses a standard design, so no optional sealing or high-inertia features are applied. For vertical axes that depend on mechanical holding devices, the motor is supplied without a holding brake, which reduces overall length and mass. By combining the series-specific winding and size, the motor supports precise torque and speed regulation in closed-loop industrial automation.

The stator uses winding code 0450, and the motor has a motor length B that balances thermal capacity against overall weight. Drive controllers communicate through a Hiperface interface linked to a capacitive single-chip sensor that generates 16 signal periods per revolution, allowing high-resolution position tracking without optical disks. Insulation class 155 permits continuous winding temperatures up to 155 °C, and the coil set is cooled by the surrounding air path. These electrical and feedback characteristics support stable current control and accurate positioning on medium-duty servo axes.

A rotatable 240° encoder connector simplifies cable routing in tight cabinets. The housing carries an IP65 rating, so dust ingress and water jets do not affect operation, and heat is removed through natural convection rather than forced fans. Continuous duty is supported within an ambient range of 0–40 °C, and the feedback element provides single-turn absolute data at power-up. The plain-shaft interface and the lack of a holding brake make the motor suitable for applications that do not require an integrated brake.
