Product Description:

The MDD093B-N-020-N2L-110GB0 synchronous motor is manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for use with digital drive controllers, it fits the 093 size class with length code B for medium-frame axes. In industrial automation, it converts commanded current into rotary motion for positioning tables, conveyors, and tool spindles. Its permanently magnetized rotor lets the motor produce full torque from standstill, which is useful in applications that start and stop frequently or must hold position under load. This operating principle also helps the drive respond quickly at low speed during repeated indexing cycles.

The stator winding can generate a continuous standstill torque of 14.5 Nm, allowing the axis to support static loads without overheating. During motion, the motor reaches a rated speed of 2000 rpm, which supports steady operation in positioning and conveying tasks. Mechanical mounting uses a centering pilot of 110 mm, which helps keep the motor aligned with gearboxes or machine frames. Electrical power and feedback lines terminate on a front-mounted connector, which simplifies cable connection where space around the motor is limited. The housing uses the standard uncooled design, so surrounding airflow must carry away excess heat during operation.

The connection hardware is oriented on side B, so cables exit toward the rear of the motor. A plain shaft provides the coupling interface, and the motor uses a single shaft end. Rotor balance uses standard balancing, and position data is supplied through digital servo feedback (DSF) for closed-loop control. This feedback arrangement allows the controller to monitor rotor position and speed throughout acceleration and deceleration. The motor is built with a shaft seal, which helps limit contamination at the shaft opening. It is supplied without a blocking brake, so external holding must be used when the application needs the shaft locked at a standstill.
