Product Description:

Bosch Rexroth Indramat manufactures the MDD071C-N-030-N2S-095GA2, a synchronous AC motor within the MDD Synchronous Motors series. It is supplied as a motor for digital drive controllers and is intended to provide precise servo motion for automated handling, packaging, and machining axes in industrial cells. The standard housing, plain shaft, and blocked shaft end on side B make the unit suitable for compact mechanical frames that rely on direct coupling to a load.

During continuous stall conditions, the rotor can deliver 6.6 Nm without exceeding rated thermal limits. At its nominal operating point of 3000 rpm, the motor aligns with the speed range used by compatible drive modules for high-cycle positioning. The flange seats against machine brackets through a centering diameter of 95 mm, which helps maintain radial alignment. Position and velocity are closed-loop controlled with digital servo feedback (DSF), which sends incremental data to the drive for rapid correction. Braking torque of 6.5 Nm comes from the integrated blocking brake, so vertical or suspended loads can be held when power is removed. Electrical power and encoder lines exit through a plug-in connector for straightforward cable routing, while IEC standard balancing helps limit vibration during speed ramps.

Cabling exits toward the front because the power and feedback ports are oriented on Side A, which is helpful when motors are mounted in rows. The frame follows size code 071, and the active magnetic stack corresponds to length code C, a combination that balances inertia with torque density for mid-range axes. A fitted shaft seal helps contain lubricant and resist splash, while the plain shaft geometry eases coupling to clamping hubs or clamp collars. Additional design elements include a single centering shoulder and the absence of a secondary shaft extension, which helps keep the motor compact.
