Product Description:

Bosch Rexroth Indramat manufactures the MDD093A-N-030-N2M-110GB2, a synchronous motor in the MDD Synchronous Motors series that works with digital drive controllers for closed-loop motion control in industrial automation. Classified as a motor for digital drive controllers, it converts commanded current into proportional torque and speed for conveyor sections, pick-and-place heads, and similar equipment. Its designation places it in the 93 mm frame class with the A-length subcode, giving it a compact footprint for medium-power axes where installation space is limited. This arrangement supports accurate speed regulation and repeatable positioning in machines that need responsive servo performance.

A 110 mm pilot diameter centers the motor on standard mounting flanges, and the rotor is ground to standard balancing quality to reduce vibration during operation. Rated continuous torque at standstill is 9.2 Nm, so the motor can support loaded axes during low-speed or holding phases commanded by the drive. Under nominal excitation, the rotor reaches 3000 rpm, which suits fast indexing and general servo positioning tasks. Power and feedback conductors exit on side B, and a keyed circular connector provides a compact cable connection. The housing and shaft end use the standard configuration for the series, and the A length code indicates the shortest stator stack in the 093 frame size.

For static holding, the motor is equipped with a blocking brake that supplies 22 Nm of holding torque when de-energized, which helps prevent load drift on vertical axes. Position data is returned through digital servo feedback (DSF), supported by an integrated multiturn absolute encoder, so the drive can recover the shaft position after power cycles. A shaft seal is installed to limit the ingress of cutting fluids, and the rotating element is a plain shaft without a secondary output on side B. This shaft style supports direct coupling to gearboxes or belt pulleys while keeping the output geometry simple.
