Product Description:

The MSK100B-0400-NN-S1-AP2-NNNN is a synchronous servo motor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. Serving as a rotary actuator for precision positioning and speed control, it pairs with IndraDrive controllers to move axes in packaging, printing, and handling equipment. A standard housing, optical encoder, and integrated brake let the unit deliver controlled torque and accurate feedback in compact automation cells. The motor is intended for servo-driven axes where stable motion, reliable holding at standstill, and consistent response to command changes are important.

Heat generated in the stator is removed by natural convection, so the motor can be installed without auxiliary fans if free air circulates around the frame. This cooling method keeps the enclosure simple and avoids the need for separate forced-air components on the motor. Position data are transmitted through a Hiperface interface, and an internal optical disc produces 128 signal periods per revolution for accurate interpolation inside the drive. The electrically released brake provides 70 Nm of static torque to secure vertical loads whenever power is off. To withstand washdown spray, airborne oil mist, and dust, the housing is sealed to IP65. The standard mechanical design and B-length body pair with winding code 0400 so the motor matches the intended drive parameter set.

The drive shaft is a shaft with keyway, enabling direct attachment to pulleys or gearheads through common hub connections. Insulation is classified at 155, supporting elevated winding temperatures during demanding duty cycles. Continuous service is permitted when the surrounding air stays between 0–40 °C, which suits common indoor industrial conditions. Because the feedback device tracks a single mechanical turn, its single-turn layout simplifies zero referencing on short-stroke axes while still providing absolute position at startup.
