Product Description:

The MDD090A-N-020-N2L-130GR0 synchronous motor is produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Supplied as a motor for digital drive controllers, it converts regulated drive output into rotational motion for positioning and velocity tasks on automated transfer stations, packaging axes, and general motion platforms. With frame size 090 and the compact A-length stack, the unit supports installations where footprint is limited while still providing the torque reserve needed for medium-inertia loads.

Its continuous standstill torque is 3.7 Nm, which gives the drive enough holding force for indexing or tensioning duties without overheating. The nominal operating speed reaches 2000 rpm, balancing dynamic response with mechanical life in most point-to-point cycles. Mounting alignment is aided by a centering diameter of 130 mm, and the rotor uses standard balancing to limit vibration during acceleration. Power and feedback leads exit on the right side, and position information is carried through digital servo feedback (DSF). A keyed plug carries stator power, which helps simplify cable routing in side-mounted cabinets and supports stable signal transmission over long cable runs. The housing and shaft end use a standard configuration that supports common motor mounts and coupling arrangements.

The motor is supplied without a blocking brake, so position holding during power-off conditions must be handled by the connected drive or gearbox. It uses a connector plug system that allows replacement without rewiring the entire cable set. Ingress protection at the output side is reinforced by a shaft seal, which helps keep dust and lubricants away from the bearings. Torque is transmitted through a plain shaft, and the absence of keys or a side-B shaft extension helps reduce runout while supporting clamped hub connections during rapid reversals.
