Product Description:

The MSK100D-0300-NN-M2-LG0-RNPN is a synchronous servo motor built by Bosch Rexroth Indramat and supplied within the MSK IndraDyn S Synchronous Motors series. As a rotary actuator for industrial automation, it converts regulated electrical energy from a drive into controlled shaft motion for positioning or speed-controlled tasks on packaging lines, handling systems, and machining axes. Its closed-loop design supports repeatable motion on axes that must start, stop, and reverse accurately during normal machine cycles. The motor is intended for use with a compatible servo drive that manages current, speed, and position in a coordinated axis system.

Heat produced in the stator is removed by natural convection, so the housing must be mounted where ambient air can circulate freely. Position feedback is routed through a single-cable EnDat2.1 interface that carries both data and power to the encoder. The encoder provides 2048 signal periods per mechanical turn, and its optical scanning method helps maintain stable signal quality over time. A multiturn absolute feedback system lets the drive read rotor position and completed revolutions immediately after power-up. A plain shaft transfers torque to a coupling without a keyway, and the motor is supplied without a holding brake, so loads at rest require external restraint.

The left-side power connector can simplify cable routing when the motor faces the machine front. Continuous operation is permitted in ambient temperatures from 0 to 40 °C, and the insulation system uses thermal class 155 for the windings. Internal conductors use winding code 0300 to match the electrical profile assigned to this torque class. The housing has an IP65 protection rating, which supports use on exposed machine axes subject to dust and low-pressure water spray. Size 100 with length D gives the motor a large frame and a long housing.
