Product Description:

The MDD090A-N-030-N2L-130PA1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It serves as the rotary element in digital drive controllers, supplying commanded motion for positioning axes in production equipment. This motor type is suited to precise speed and position control in packaging, handling, and similar automated systems. The motor has size 090 and the short A length, which gives it a compact form for machines with limited installation space. Its housing and rotor balancing are standard, so the unit suits general automation duty without special mechanical provisions.

Mounting is centered by a 130 mm pilot diameter that aligns the flange with adjoining machine faces. Power and feedback cabling exit through a sealed connector on side A, which keeps both connections on one face of the enclosure and simplifies routing. Keeping the electrical outlet on one side also reduces cable crossover near the mounting face. At standstill, the motor can deliver a continuous torque of 3.7 Nm. During operation, it reaches a nominal speed of 3000 rpm, which suits common servo applications. The output uses a keyway shaft with a shaft seal, and the shaft is single-sided with no extension on side B.

A blocking brake is integrated for load holding, and it provides up to 6.5 Nm of static torque when drive current is removed. Position verification is handled by digital servo feedback (DSF), allowing the drive to read rotor position directly for closed-loop control. DSF also supports stable commutation and accurate speed regulation across normal operating ranges. This arrangement keeps wiring compact because brake supply and feedback are routed through the main motor connection. The sealed output arrangement helps limit contamination at the drive end and keeps rear clearance needs low.
