Product Description:

The MSK071C-0300-NN-M3-UG0-NNNN from Bosch Rexroth Indramat is a synchronous servomotor in the MSK IndraDyn S Synchronous Motors series. It serves as the rotary actuator in industrial automation, translating controlled electrical input from an IndraDrive amplifier into precise torque and position for packaging lines, gantry axes, and tooling spindles. It is intended for servo-controlled axes that require repeatable motion during start-stop cycles and coordinated multi-axis operation. Bosch Rexroth supplies this motor as a standard design unit so it can fit existing machine footprints without special adapter brackets or custom couplings.

Heat is removed by natural convection, eliminating the need for external blowers and simplifying cabinet layouts. Position feedback is routed through a Hiperface interface, and within the motor a capacitive sensor generates 16 signal periods. The feedback unit is a multi-turn absolute encoder, so the drive retains position over 4096 revolutions even after power loss. A rotatable 240° connector allows the cable exit angle to be set during installation. With a body length of C, the motor balances inertia and continuous torque for mid-range load requirements. This assembly ships without a holding brake, which reduces mass in applications where static friction or drive torque can maintain position.

The motor operates reliably between 0–40 °C, and its housing is sealed to IP65 to block dust and water jets on production floors. A plain shaft provides a smooth coupling surface for backlash-free clamp collars or shrink discs, which supports accurate torque transfer and alignment. The insulation system is rated to class 155 for continuous winding temperatures up to 155 °C. Electrical characteristics are set by winding code 0300, allowing the connected drive to use the correct current and voltage parameters for dynamic duty cycles.
