Product Description:

The MSK100B-0400-NN-S1-AP0-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat and supplied within the MSK IndraDyn S Synchronous Motors series. As a permanent-magnet AC motor, it converts commanded current into controlled rotary motion for closed-loop axis operation. Because it works with a servo controller, the drive can correct speed deviations and maintain commanded position under changing load conditions. This allows the motor to support packaging lines, metal-cutting centers, and material-handling gantries where precise motion control is required.

The motor uses a standard housing with natural convection cooling, so no external blower or liquid circuit is required. This cooling method reduces auxiliary hardware around the motor and keeps the installation compact. Mechanical connection to the load is handled by a shaft with a keyway, and the stator-mounted power lead exits on the A-side to simplify routing in right-hand cabinet layouts. That shaft style supports positive torque transmission to couplings, pulleys, or gearbox inputs. The motor has a size of 100, and the B frame length gives it a longer active stack within this housing size. Winding code 0400 identifies the electrical layout that matches the voltage and current range of the intended drive inverter. The unit is supplied without a holding brake, so static load retention must be provided externally when power is removed.

For feedback, the motor carries a Hiperface absolute encoder that communicates over a bidirectional serial channel. Its optical scan head provides 128 signal periods per revolution, and the drive can interpolate that signal for finer position evaluation. The sensing method is optical, so adjacent power cables do not affect the feedback with magnetic interference. The encoder is a single-turn type, which reports angular position within one mechanical revolution and supports stable commutation and repeatable homing after power-up. Absolute position information is available immediately within one turn, which reduces dependence on incremental counting for basic angle recognition.
