MDD025A-N-100-N2K-040MD0
The Bosch Rexroth Indramat MDD025A-N-100-N2K-040MD0 is a synchronous servo motor positioned in the MDD Synchronous Motors series. Designed as a drive element for digital drive controllers, this compact unit converts electrical command signals into precise rotary motion in automated assembly stations, pick-and-place gantries, and miniature positioning tables. Its mechanical dimensions correspond to the 025 frame class, giving machine builders a lightweight actuator that integrates directly with Indramat drive electronics for closed-loop velocity and torque regulation.
At standstill the motor can deliver a continuous torque of 0.33 Nm, which is the maximum mechanical load it can hold without overheating when locked in position. Once in motion it reaches a nominal speed of 10000 rpm, allowing high cycle rates in short-stroke mechanisms. Rotor location is reported by an Integrated absolute encoder; this sensor feeds position data to the controller so homing is unnecessary after power loss. For velocity loops that rely on analog angle information, the motor also carries Resolver feedback. The centering shoulder measures 40 mm in diameter, aligning the stator concentrically with the mounting flange. Standard dynamic balancing minimizes residual vibration, and the A-length code denotes the shortest housing available within the 025 size group, helping conserve envelope depth in dense multi-axis racks.
Cabling exits on the rear face designated as Side B, simplifying routing when multiple axes are stacked in parallel. Power and signal conductors connect through a single Connecting cable with coupling unit, which supports quick replacement. The unit is supplied without a blocking brake, so any static holding duty must be handled by the drive or an external clamp. The shaft uses a hardened steel keyway profile and is shipped without a side B extension or a shaft seal, making it suited for clean enclosures where contamination ingress is already controlled by the machine housing.
