Product Description:

Bosch Rexroth Indramat manufactures the MSK100D-0300-NN-M1-BP2-NSNN as part of the MSK IndraDyn S Synchronous Motors series. The unit is an AC servo motor designed to supply finely regulated torque and speed to automated positioning stages, presses, and conveyor sections in integrated production lines where closed-loop electrical drives replace pneumatic or hydraulic actuators. In these applications, the motor converts controlled electrical input into stable rotary motion for accurate axis movement and repeatable machine timing. Its operating role fits transfer systems, indexing mechanisms, and driven assemblies that depend on closed-loop motion.

The motor sheds heat by natural convection, so adequate clearance around the housing is required instead of auxiliary fans or liquid circuits. Rotor position feedback arrives through a Hiperface optical encoder that produces 128 signal periods per revolution, and this feedback supports accurate speed and position control. The encoder is multiturn absolute, preserving angular data over 4,096 turns after power loss and reducing the need for a homing cycle at startup. An electrically released brake provides 70 Nm of holding torque for secure stopping on vertical or suspended axes. Mechanical integration includes a keyed shaft, a B-side power connector, and winding code 0300 for compatibility with IndraDrive amplifiers.

The housing uses motor length D and retains the bolt circle of motor size 100, so it fits the dimensional pattern of that frame. Insulation built to thermal class 155 supports elevated winding temperatures, but ambient air must remain within 0–40 °C during continuous duty. The enclosure is sealed to IP65, helping block dust and low-pressure water jets during normal industrial use. This sealing allows installation close to the machine process without a separate protective cabinet.
