Product Description:
The MSK100B-0400-NN-S2-AP1-RNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. Intended for integration in industrial automation lines, the motor converts electrical energy into tightly synchronized rotary motion that supports indexing tables, gantry drives, and packaging equipment. Its mechanical design supports increased concentricity, and the B-length housing fits into compact machine spaces where axial dimensions are limited while still providing the dynamic response required by modern servo loops. This operating role makes the motor suitable for applications that require accurate speed control, repeatable positioning, and stable torque delivery during rapid start-stop cycles.
Heat generated in service is removed by natural convection, so no external fan or liquid circuit is required when the motor is mounted in free air. The sealed housing carries an ingress rating of IP65, allowing operation in dusty or splash-prone zones. For position feedback, the optical encoder uses an EnDat2.1 digital interface and resolves rotor angle into 2048 signal periods per revolution in single-turn format, giving the drive controller precise commutation data. An electrically released brake provides 32 Nm of holding torque for load retention during power-off or emergency stop conditions. This combination supports applications where controlled stopping and retained position are important during interrupted operation.
Mechanical attachment is simplified by a shaft with keyway that transmits torque to standard couplings while helping prevent slip. The motor sustains full performance across an ambient range of 0–40 °C, and its windings use insulation rated to class 155 for thermal endurance during continuous cyclic duty. With a frame size of 100, the motor uses the 0400 winding code and an A-side power connector for compatibility with suitable IndraDrive amplifier outputs. Cable routing from the A side can help in installations where clearance at the opposite end is limited, and the shaft arrangement supports positive torque transfer in repeated acceleration and deceleration cycles.
