Product Description:

The MDD025A-N-100-N2G-040ME1 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It uses the A length code in the 025 frame size with a standard housing and rotor balancing, making it suitable for confined assemblies in pick-and-place machines or miniature test rigs. Designed to work with digital drive controllers, the unit converts controlled current into fast rotary motion for positioning stages, small spindle drives, and pick-and-place modules. In industrial automation, it serves as the electromechanical link between the power electronics and the mechanical load while delivering repeatable speed and torque in a small footprint.

Its centering diameter measures 40 mm, which helps the motor seat accurately in precision mounting flanges. At standstill, the motor can apply a continuous torque of 0.33 Nm without exceeding thermal limits, and routine operation allows the rotor to reach a nominal speed of 10000 rpm for rapid cycle execution. A rear-mounted blocking brake provides 1.0 Nm of static holding torque, so the axis can remain locked during power loss or an emergency stop. Rotor position is reported through resolver feedback, which provides rotor angle information with strong immunity to electrical noise. All power, brake, and sensor leads exit on the left side, which helps keep cable routing orderly along compact machine frames.

The output shaft uses a keyway profile that accepts keyed hubs or pulleys and helps prevent slippage under dynamic load. The housing is supplied without a shaft seal, so the front bearing area should be protected from coolant splash or abrasive dust. Electrical power, brake wiring, and feedback signals are routed through a single connecting cable with a coupling unit, which reduces connector count and keeps the external connection layout compact. This arrangement is well suited to tightly packed machinery where limited space around the motor can make cable management more difficult.
