Product Description:
The MSK100B-0300-NN-S3-BP1-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is built for closed-loop motion tasks in industrial automation where accurate torque delivery and high positioning repeatability are required. By combining a compact frame with an integrated single-cable feedback concept, the motor streamlines wiring between the machine axis and the drive controller while maintaining sealed protection suitable for plant-floor installation.
Thermal energy is removed from the housing through natural convection, so no external blower or liquid circuit is needed. A multiturn-ready drive can read the motor’s Hiperface encoder interface, which provides 16 signal periods per revolution for commutation. When power is removed, an electrically released brake holds the shaft, and it can sustain up to 32 Nm of static torque to prevent drift on vertical axes. The stator winding coded 0300 is paired with the B-length rotor in a 100 mm frame, matching the continuous torque class to medium-inertia loads. The IP65 housing keeps dust and directed water jets away from internal components.
The internal measuring system relies on capacitive scanning and is configured as a single-turn device, giving absolute position feedback for one mechanical revolution without batteries. Service routing is simplified because the power connector sits on the B-side of the stator, and the motor uses the standard build for this series. The laminated core and insulation system meet class 155 thermal requirements, allowing the motor to operate continuously within an ambient range of 0–40 °C. The output uses a shaft with a keyway, which provides positive mechanical coupling to gears, pulleys, or couplings without relying only on clamping friction.
