Product Description:
The MSK075C-0300-NN-M1-UP1-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As part of an IndraDrive system, it transforms controlled three-phase current into regulated mechanical power for indexing tables, gantry axes, and packaging lines. The design supports fast feedback, precise torque control, and long-term positional accuracy in industrial automation cells. Because the feedback system is integrated into the motor, the connected drive can respond quickly to changing load conditions during acceleration, deceleration, and short indexing moves.
Its housing carries a protection rating of IP65, sealing the stator and feedback assemblies against dust ingress and low-pressure water jets commonly found in production areas. Heat generated in the windings is removed by natural convection, so no external blower or liquid manifold is required. A rotatable 240° feedback connector lets the cable exit be aligned with the machine frame, and the optical encoder communicates through the Hiperface protocol. Within the encoder, a code disk provides 128 signal periods, and the multi-turn counter retains absolute position through power cycles. Winding code 0300 matches standard IndraDrive amplifiers. The motor has size 075 and length C, while the electrically released holding brake provides 23 Nm of static torque for load holding at standstill.
The encoder supports Multiturn Absolute operation and records up to 4,096 revolutions, which reduces the need for a homing routine after restart. Mechanical power is transferred through a shaft with keyway, giving pulleys or gear hubs a positive drive connection. Continuous duty is supported at ambient temperatures from 0-40 °C, and the windings use insulation class 155 to withstand the internal heat associated with repetitive cycling. This motor is well suited for compact axes in pick-and-place systems, transfer units, and packaging equipment where repeatable motion and stable position retention are important.
