Product Description:

The MSK100C-0450-NN-S1-AP0-NNNN is a permanent-magnet AC servo motor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It uses the standard mechanical design for this frame size, which supports installation in established machine layouts. Serving as a compact IndraDyn S synchronous servomotor, it converts electrical drive commands into rotational motion for positioning axes, pick-and-place actuators, and similar closed-loop automation tasks. When paired with a compatible drive, it supports accurate speed regulation and repeatable positioning in automated equipment.

Its thermal management relies on natural convection, so heat leaves the housing without fans or liquid circuits, and machine layouts must allow free airflow around the frame. Position feedback is supplied by a Hiperface optical encoder that works with drives using digital-analog hybrid channels, and the sensing head resolves rotor position over 128 signal periods per revolution. Because the scanning principle is optical, the encoder maintains high accuracy at low speed and avoids wear associated with magnetic strips. The connector for power conductors is mounted on the motor’s A-side, simplifying cable routing when the housing is oriented with the shaft facing forward.

The feedback unit is a single-turn device, so absolute angle is reported within one revolution and multi-turn counting is left to the drive control. The frame is size 100 with length code C, giving a stator package that balances torque output against installation depth in gantry sliders or tool heads. Mechanical power is transmitted through a shaft with a keyway, allowing straightforward coupling to pulleys or gearboxes while helping prevent slippage under reversing load. Electromagnetic characteristics are matched to drive modules by winding code 0450, which corresponds to the voltage constant and rated current used for medium-inertia axes. The motor is delivered without a holding brake, so position holding during power-off periods must be provided by external clamping or by drive-generated torque where the application permits.
