Product Description:

Bosch Rexroth Indramat manufactures the MSK061C-0200-NN-M2-UG0-RNNN as part of the MSK IndraDyn S Synchronous Motors series. The unit functions as a servo actuator for coordinated motion in packaging, handling, and metal-forming equipment. Its frame provides continuous torque suited for medium-power tasks while keeping installation depth short. Because it is supplied without a holding brake, the axis must rely on a mechanical lock or drive-generated holding torque to maintain position during power loss.

The IP65 enclosure blocks dust ingress and withstands low-pressure water jets. Heat produced in the stator is removed through natural convection, eliminating the need for fans or liquid circuits and keeping the motor body mechanically simple. Position feedback is supplied by an EnDat2.1 optical encoder that resolves the rotor angle into 2048 signal periods per revolution for precise closed-loop control. The encoder connects through a plug that can be rotated through 240°, which helps with cable routing where space is limited. The motor also uses an increased-concentricity design to keep shaft runout low, and the 061 frame with length code C gives a balanced mix of torque output and inertia for mid-range axes.

The drive end uses a plain shaft, so torque is transferred without keyways and precision couplings can be fitted with minimal backlash. Position data remains available over multiple turns because the feedback unit is a multiturn absolute system, allowing the drive to know rotor position after power-up without a homing routine. Safe operation is permitted at ambient temperatures from 0 to 40 °C, which matches common industrial cabinet and machine-area conditions. The motor uses insulation class 155, allowing winding temperatures up to 155 °C without varnish degradation. Winding code 0200 sets the electrical behavior for operation with compatible servo drives that supply moderate current and stable dynamic response.
