Product Description:

The MSK050C-0450-NN-S1-UG0-NSNN is a frame-050 synchronous servomotor developed by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S unit, it converts regulated electrical power from a compatible Rexroth drive into precise rotary motion for automated positioning, packaging, and handling stations. The motor is intended for closed-loop motion tasks where stable torque delivery and accurate speed control are required during repeated operating cycles. The frame size supports compact axis layouts where installation space is limited but servo response must remain consistent. Its housing uses the standard explosion-protected design for this version, allowing operation in areas where flammable gases may be present without external purging hardware.

Cooling is provided by natural convection, which removes heat without a fan and helps keep the motor compact. A sealed aluminum enclosure with an IP65 rating resists dust ingress and low-pressure washdown, making direct machine mounting possible in many installations. Position feedback is carried over the Hiperface protocol, so power and data share the same cable for simpler routing. The encoder supplies 128 signal periods per revolution, giving the drive a stable signal for smooth speed regulation and position control. The motor uses a plain shaft with no keyway, which suits clamp couplings and helps reduce runout. Because the motor does not include a holding brake, any required holding force must be supplied by external means when power is removed.

The winding insulation corresponds to class 155, allowing the motor to operate at elevated internal temperatures within its thermal limits. The motor uses winding code 0450, which sets the electrical characteristics expected by compatible IndraDrive controllers. Power and feedback connections exit through a connector that is rotatable through 240°, making cable orientation easier in confined machine layouts and helping reduce strain at the connection point. This arrangement also helps the motor fit equipment with nearby guards, gearboxes, or cable tracks. Rated operation is specified for ambient temperatures from 0 to 40 °C, provided the cooling surfaces remain unobstructed and airflow around the finned housing is not blocked.
