Product Description:

The MDD090B-N-030-N2L-110PB0 is a brushless AC servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded phase currents into tightly regulated rotary motion for pick-and-place stations, indexing conveyors, and packaging axes in general industrial automation. Its 090 frame and B length share mounting geometry with earlier MDD units, which helps it fit existing machine layouts. The motor is intended for precise speed and position control where repeatable response is required through frequent starts and stops.

At the mechanical interface, the centering shoulder is 110 mm, ensuring concentric alignment with gearheads or mounting flanges. Power, brake, and feedback leads exit on side B, and the molded connector keeps the wiring arrangement compact at the motor. Under steady stall conditions, the rotor delivers 7.2 Nm of torque, which supports moderate static loads without thermal overload. When driven at its rated electrical frequency, the shaft reaches 3000 rpm, matching the duty profile expected from the 090 size core and the B length stack. Standard housing sections and factory balancing help keep vibration low at operating speed.

Position feedback is provided through digital servo feedback (DSF), which sends high-resolution position data directly to the drive amplifier for closed-loop control. The unit is supplied without a blocking brake, so holding torque during power-off conditions must come from the drive or an external device. Torque is transmitted through a keyway on the single output shaft, and a shaft seal protects the front bearing area from light coolant splash. The motor uses a single shaft end without a rear extension, making it suitable for direct coupling arrangements where only one driven output is needed.
