Product Description:

The MDD071A-N-030-N2T-095PB1 is a synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, so it pairs with Indramat power modules that supply regulated three-phase current and closed-loop control signals. The A-length frame keeps mass low, while the 071 size provides enough stator volume for light to medium feed axes on packaging machinery, pick-and-place gantries, or small tool spindles. This makes it suitable for positioning tasks that require accurate speed control and repeatable response during frequent starts and stops.

A centering diameter of 95 mm allows direct flange mounting without additional alignment sleeves. At standstill, the motor can deliver 2.2 Nm continuously, which supports steady holding or low-speed cutting force before thermal limits are reached. During normal operation, the rotor tracks commands up to 3000 rpm, matching common speed ranges in industrial drive systems. A permanent-magnet holding brake rated at 3.0 Nm is integrated, and its blocking design secures vertical loads when power is removed. Motion and position loops are closed through digital servo feedback (DSF), which returns high-resolution signals to the drive for current and velocity regulation.

An integrated multiturn absolute encoder stores angular position across power cycles, eliminating homing sequences after an emergency stop. Power and feedback cables exit on the Side B face through a sealed connector, so cabinet wiring can stay short and orderly. The shaft is machined with a keyway and protected by a shaft seal to help block coolant or dust from entering the housing. The rotor uses standard balancing quality to minimize vibration at top speed, and the single-ended shaft leaves no side-B projection to save space. This arrangement is useful where the rear of the motor must remain clear for mounting plates, couplings, or adjacent machine parts without extending the assembly.
