Product Description:

The MSK050C-0450-NN-M2-UG0-RNNN belongs to the MSK IndraDyn S Synchronous Motors series from Bosch Rexroth Indramat. This AC servo motor is used on controlled axes that require precise speed and torque regulation in packaging, printing, and material-handling equipment. A motor size of 050 combined with length C gives the unit a compact housing that fits shallow machine spaces while remaining compatible with standard Rexroth drive amplifiers. Its design supports responsive motion on indexing, transfer, and feed axes where stable control is required during frequent starts and stops.

The motor relies on natural convection for heat removal, so airflow around the housing must remain unobstructed during continuous operation. Feedback passes through the bidirectional EnDat2.1 interface, and the optical encoder provides 2048 signal periods per revolution for accurate commutation and position control. The feedback connector can be rotated to simplify cable routing in crowded machine layouts, and the die-cast housing is sealed to IP65 to keep out dust and low-pressure water jets. Class 155 insulation supports normal thermal loading, the motor can operate in ambient temperatures from 0 to 40 °C, and the unit is supplied without a holding brake. Static load holding must therefore be provided by drive torque or by an external braking device when the axis is stopped.

Mechanical alignment is improved by the increased concentricity design, which helps reduce radial runout when the motor is coupled to gearheads or ball screws. Torque is transmitted through a plain shaft, and absolute position is retained after power loss because the encoder operates in multiturn absolute mode. During installation, the feedback plug can be pivoted through 240°, which allows side or rear cable exits without changing the mounted footprint. Because position information remains available after a power cycle, restart sequences can proceed without a separate homing move.
