Product Description:

The MDD025A-N-100-N2K-040FE1 is a synchronous motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed as a motor for digital drive controllers, it delivers fast rotary actuation for compact automation axes, small gantries, indexing devices, and other space-limited motion systems on the factory floor. The unit converts controlled three-phase stator currents into torque and speed that can be synchronized with servo amplifiers in multipoint motion sequences and short, repetitive positioning tasks.

The mechanical core is balanced to the standard grade to minimize vibration when coupled to light loads. A centering pilot of 40 mm simplifies concentric alignment to gearboxes or flanges. At standstill, the stator can sustain 0.33 Nm of continuous torque, providing holding force for low-inertia tooling. When energized at rated frequency, the rotor reaches 10000 rpm, enabling rapid cycle times in pick-and-place stations. For safe positioning during power loss, an internal blocking brake develops 1.0 Nm of static torque. Rotor position is detected by an integrated absolute encoder, and velocity information is derived from resolver feedback so the drive can close precise motion loops.

Electrical power and feedback exit on the left side and are routed through a connecting cable with coupling unit, which helps simplify cable routing in tight machine cabinets and on densely packed mounting plates. The frame size is 025, which pairs naturally with small inverter channels used on compact axes. A plain shaft with a standard end geometry and no secondary shaft on side B simplifies coupling to precision pulleys or compact transmission elements. The motor length is coded as A, and its housing follows the standard enclosure outline. Because the assembly is supplied without a shaft seal, it is intended for clean, dry environments where contamination is controlled.
