Product Description:

The MSK100B-0400-NN-S1-BP0-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Built in the standard housing configuration, it converts commanded current from an IndraDrive inverter into controlled torque and speed for industrial axes that require high repeatability. Typical roles include moving pick-and-place heads, indexing rotary tables, or driving precision linear stages through a coupling or the shaft’s integrated keyway. Compact construction and an internal feedback system allow the motor to mount close to the load, reducing mechanical backlash and improving dynamic response.

In operation, the stator windings dissipate heat through natural convection, eliminating added fans or liquid circuits and simplifying cabinet layouts. Rotor position data is delivered over a Hiperface interface; this bidirectional protocol provides absolute angle information and stores motor parameters inside the feedback system. The embedded single-turn sensor resolves 128 signal periods per mechanical revolution, and interpolation inside the drive produces very fine position commands. Because the measuring principle is optical, performance remains stable even near transformers or large conductors. The motor is supplied without a holding brake, so machines that require static holding torque must rely on drive clamping current or an external mechanical lock.

The electromagnetic design uses the 0400 winding code, which matches the rated voltage constant and current to medium-voltage IndraDrive supplies. The housing follows motor size 100, giving a 130 mm flange square and a shaft diameter appropriate for couplings in the 25 kW class. The extended core length marked as motor length B increases active iron and copper, raising continuous torque while keeping the mounting face unchanged. Mains power reaches the stator through a power connector on side B, allowing cable routing on the machine’s service side and leaving the opposite face free for encoder leads and ventilation clearance. This arrangement supports installations where access space around the motor is limited.
