Product Description:

The MDD025B-N-100-N2G-040PA1 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended to pair with compatible digital drive controllers, it converts commanded current into proportional torque for precise axis positioning. The motor’s 025 frame and B-length housing make it suitable for space-restricted installations such as electronic component handlers, miniature gantries, and spindle orientation modules in automated production lines. Its compact format also helps preserve working space around adjacent tooling and sensors in tightly packed machine layouts.

The mounting interface employs a centering diameter of 40 mm, allowing the motor face to align concentrically with gearboxes or machine plates without additional shims. Power and feedback conductors exit on side A of the housing, so cabinet layouts must leave clearance on that face. A single multi-pin connector handles both motor phases and signal conductors, simplifying cable routing and reducing wiring errors. At standstill, the electromagnetic system can develop 0.60 Nm of continuous torque, enabling low-inertia loads to hold position while remaining within thermal limits. During normal operation, the rotor can reach a rated speed of 10,000 rpm, supporting high throughput when coupled with fine-pitch mechanical transmissions.

An integrated blocking brake supplies 1.0 Nm of holding torque to lock the shaft once power is removed, preventing back-driving on vertical or overhung loads. Rotor position is monitored through resolver feedback, which provides rotor angle data that remains stable during rapid acceleration. The output shaft uses a keyway to transmit torque without slippage, and a fitted shaft seal helps protect the internal bearings from coolant splash or airborne particles. Standard dynamic balancing limits vibration across the full 10,000 rpm range, while the absence of a secondary shaft end reduces overhung mass and simplifies coupling alignment.
