Product Description:

The MDD093A-N-020-N2M-110GB2 is a synchronous AC servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It belongs to motor size 093 and length code A, giving it a compact body that fits medium-frame machine axes. As a motor for digital drive controllers, it pairs directly with Indramat power modules and supplies finely metered torque to conveyor, press, and pick-and-place applications. Its synchronous design supports accurate response to changing load commands during closed-loop motion.

At standstill, the unit can exert a continuous torque of 9.2 Nm, and its nominal mechanical speed is rated at 2000 rpm. A blocking brake integrated at the fan end delivers a retaining force of 22 Nm to hold vertical loads when power is removed. Rotor alignment uses standard balancing, so vibration remains controlled when the plain shaft mates with external couplings. Mounting accuracy is assisted by a centering diameter of 110 mm. Power and feedback conductors exit on side B through a circular connector, and the keyed connection helps prevent incorrect orientation. The housing uses the standard uncooled casting, and the motor has a single shaft end on the drive side only.

Position information is generated by the integrated multiturn absolute encoder, allowing the controller to track axis location across power cycles without mechanical homing. Signals travel through digital servo feedback (DSF), which keeps response fast for high-bandwidth motion loops. A shaft seal on the output end helps stop oil migration and protects the bearings from airborne coolant. The plain shaft geometry simplifies coupling while avoiding keyway stress points. The absence of a shaft extension on the non-drive side leaves more room for adjacent equipment, which can be useful in tightly arranged machine layouts. This arrangement also helps keep the motor envelope clear around the rear end for nearby guards, brackets, or cable routing.
