MSK030C-0900-NN-ME-UG0-NNNN
The MSK030C-0900-NN-ME-UG0-NNNN is a permanent-magnet synchronous motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In an automation cell, this device functions as a rotary actuator that converts drive current from a Rexroth controller into precise shaft motion for indexing tables, pick-and-place arms, or small packaging axes. Its compact frame and feedback interface suit machines that need accurate torque and position regulation while maintaining a small mechanical envelope. This arrangement supports repeatable motion on compact axes where installation space is limited.
Thermal management is passive because the housing releases heat through natural convection, avoiding external fans and simplifying enclosure layouts. The feedback plug is rotatable through 240° to align the encoder cable with cabinet routing, which is helpful in tight spaces. The motor has motor size 030, which suits sub-kilowatt duty points. It also has motor length C, which provides additional active stack height for higher torque density within the same mounting pattern. A plain shaft exits the front bearing set, so torque is transmitted with friction couplings or collets rather than keys, reducing micro-motion and easing installation.
The motor uses the Standard version, indicating normal flange geometry and bearing play that fit most gearheads. Electrical characteristics come from winding code 0900, a coil set intended for moderate speed ranges when paired with 320 VDC link voltages. Because the motor is supplied without a holding brake, drive torque or an external clamp must hold vertical loads during power-off. It is an IndraDyn S synchronous servomotor with a sinusoidal back-EMF profile and an integrated high-resolution optical encoder for fine position loops. This combination supports predictable behavior under current control and accurate positioning during repeated indexing moves.
