Product Description:

The MSK075E-0200-NN-M1-UG0-NNNN is an AC synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servo motor, it delivers closed-loop torque and velocity control for positioning axes in automated machinery and handling equipment. It couples with IndraDrive controllers to convert electrical commands into mechanical rotation for packaging lines, gantry systems, and general motion platforms. Its synchronous design allows the controller to regulate current and rotor position together, which helps the axis respond smoothly during acceleration, deceleration, and low-speed holding.

The unit relies on natural convection for heat dissipation, so its housing must remain exposed to ambient air instead of being enclosed in a sealed cabinet. Frame code 075 indicates the motor size, and length code E uses an extended active stack for higher continuous torque than shorter motors in the same frame. Electrical behavior is indexed by winding code 0200, which matches the motor to drives with the appropriate voltage constant and current range. A plain shaft simplifies mechanical coupling because no keyway or serration interferes with hub clamping. This layout suits direct coupling arrangements that rely on frictional locking rather than keyed transmission. The cooling method also keeps the motor free of external fan hardware, which reduces added wiring and leaves the outer housing as the primary heat path.

The motor has a standard design and a feedback system intended for precise closed-loop motion. A rotatable 240° connector lets cables exit in different directions, while the multiturn absolute encoder records revolution counts beyond a single turn. Signal exchange uses the Hiperface protocol, the readhead uses an optical scanning method, and the disk yields 128 signal periods per electrical rotation for fine interpolation inside the drive. Flexible connector orientation can ease cable routing in compact machine frames and helps avoid sharp bends near the motor connection point. Because the motor is supplied without a holding brake, any required static load retention must be provided by the external mechanical arrangement or by drive-based torque. The encoder arrangement also allows the drive to retain position information across multiple shaft revolutions.
