Product Description:

The MDD093B-N-020-N2M-130PB1 is a synchronous motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where commanded current is converted into controlled shaft motion for machine tools, handling systems, and other automated equipment. Closed-loop operation helps the axis maintain stable torque and speed under changing load conditions. The motor also includes a blocking brake for load retention when power is removed, and the standard housing fits the established mounting dimensions of the product line.

The motor reaches a nominal speed of 2000 rpm, giving moderate shaft velocity for indexing and feed tasks. At standstill, it can deliver 14.5 Nm of continuous torque, which supports sustained force without overheating during rated operation. Its blocking brake provides up to 11 Nm of holding torque so vertical or suspended loads can remain in position at rest. Electrical terminations exit on Side B through a single connector, which helps keep cable routing compact. Position and velocity are reported by Digital servo feedback (DSF), allowing the connected drive to monitor rotor movement precisely during acceleration, speed control, and positioning. The rotor is balanced to a standard grade to limit vibration at rated speed.

A centering collar of 130 mm aligns the flange with precision gearboxes or machine frames, while the B frame length helps the motor fit installations with limited depth. The output shaft uses a keyway for positive torque transmission and is built as a single-ended design without a rear shaft extension. Contamination control is improved by a shaft seal, which helps limit lubricant migration along the output journal. Feedback redundancy is provided by an integrated multi-turn absolute encoder, so position remains available over multiple revolutions without requiring a battery. Motor size 093 places the unit in the mid-range of the series and suits it to compatible digital drive power stages.
