Product Description:

The MSK050C-0600-NN-M2-UG1-RNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. Within an automation cell, this motor converts electrical energy from a compatible IndraDrive inverter into mechanical rotation for feed axes, pick-and-place heads, or compact gantries. It is intended for dynamic servo applications where the inverter continuously adjusts current to match commanded motion. Size 050 and length code C identify the stator geometry, and the increased concentricity design reduces radial runout so the plain shaft can couple directly to precision gearboxes or belt pulleys with minimal vibration.

The unit is cooled by natural convection, so no external blower or liquid circuit is required because heat dissipates through the housing ribs. A protection rating of IP65 shields the interior against dust ingress and low-pressure water jets, making cabinet-free mounting feasible on many machines. The winding insulation is class 155, allowing continuous exposure to elevated winding temperatures before thermal aging begins. Operation is permitted between 0 to 40 °C, which aligns with typical shop-floor climates and avoids the need for conditioned enclosures. A plain, non-keyed shaft simplifies assembly where torque is transferred with shrink disks or radial clamping hubs. The 240° rotatable encoder connector also helps route cables in tight machine layouts.

Position feedback is provided by an optical multi-turn encoder that communicates through EnDat2.1. Its internal scale generates 2048 signal periods per revolution, and the optical scanning principle supports low jitter for high servo stiffness. Because the encoder is multi-turn absolute, the controller receives the rotor angle and revolution count immediately after power-up without a homing routine. This feedback arrangement supports closed-loop control during indexing and positioning tasks that depend on immediate position availability. An electrically released holding brake supplies 6 Nm of static torque to secure vertical loads when the drive is disabled, and it engages automatically if power is lost.
