Product Description:

The MSK050C-0300-NN-S1-UP0-NNNN is a synchronous servo motor built by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S servo motor, it converts electrical power into tightly regulated rotary motion for positioning, feed axes, and general motion control tasks in automated machinery. When paired with a compatible drive controller, it supports accurate speed and position control during repeated machine cycles. The encoder connector can be rotated through 240°, so feedback and power leads can exit in a direction that suits the cabinet layout.

It relies on cooling by natural convection, a passive method that removes heat through the frame surface and eliminates external blowers. Electrical position data are exchanged over the Hiperface interface, which carries both incremental and parameter channels. Inside the feedback unit, an optical scanning head resolves 128 signal periods per mechanical turn, giving the drive controller fine interpolation for velocity loops. Because feedback and parameter data share the same interface, the motor does not require a separate external feedback unit. The encoder is integrated into the standard motor housing, which keeps the feedback system compact.

Position referencing is absolute for the first revolution because the measuring system is single-turn. If the application needs position tracking over multiple revolutions, that function must be handled externally by the control system. Torque reaches the load through a shaft with keyway, which provides positive mechanical engagement during reversing duty. The compact 050 frame and 0300 winding support quick indexing while keeping rotor inertia suited to mid-range automation axes. The motor is supplied without a holding brake, so static loads must be secured by an external clamp or by servo lock from the drive.
