Product Description:

The MSK050B-0600-NN-M3-UG0-NNNN synchronous servo motor is manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop motion axes where compact dimensions, accurate positioning, and continuous duty capability are required. Within an automation cell, the motor converts the electrical output of an IndraDrive controller into mechanical rotation, allowing coordinated speed and torque control on packaging, printing, or material handling equipment.

The motor’s thermal management relies on natural convection, so the housing fins dissipate heat without external blowers or liquid circuits. Mechanical ingress protection is rated at IP65, permitting operation in dusty production areas that may be cleaned with low-pressure water jets. A plain shaft transfers torque to couplings or gearheads without keyways, supporting backlash-free clamping hubs. Size code 050 indicates a stator diameter suited to light-to-medium load servo axes while keeping inertia low for fast acceleration. The insulation system is class 155, allowing winding temperatures up to 155 °C in intermittent duty.

Feedback data are delivered through a Hiperface interface, and the internal encoder generates 16 signal periods per mechanical revolution. Its sensing element is capacitive, which helps resist interference from magnetic dust and stator heating that can affect optical devices. This encoder is multi-turn absolute, allowing the controller to recover position after a power cycle, and it routes through a rotatable 240° connector for flexible wiring. The armature is wound with code 0600, matching drive parameters for standard torque density. Because the motor is supplied without a holding brake, an external clamping device is required when residual torque is insufficient to secure the load.
