Product Description:

The MDD090A-N-040-N2L-130PB0 synchronous motor is manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts drive current into controlled rotary motion that can be tightly synchronized with other axes in automated cells. The 090 frame size and A length code favor compact machine layouts, and the standard housing permits direct mounting to structural members or inside protective enclosures. Acting as the prime mover, the unit supplies continuous torque and speed response that are essential for repeatable positioning and cycle-time consistency in packaging, assembly, and material-handling equipment. This operating behavior helps the motor follow rapid command changes while maintaining stable motion during repeated indexing tasks.

For static load conditions, the motor can maintain a continuous torque of 3.7 Nm at the shaft without overheating. Positioning accuracy depends on the centering pilot, and a diameter of 130 mm provides a broad contact surface that reduces runout during installation. Dynamic applications benefit from the permissible nominal speed of 4000 rpm, which matches high-frequency drive outputs without exceeding mechanical limits. Power and feedback conductors are routed to the rear because the connections are located on Side B of the housing, and a shaft seal keeps lubricants inside the bearing zone while blocking airborne contaminants. The rear cable exit can also simplify routing when the motor is mounted close to guards, machine frames, or adjacent axis components.

Encoder signals are returned through digital servo feedback, giving the controller the position data needed for closed-loop regulation. The output spindle follows a keyway pattern, enabling positive locking with pulleys or couplings. For systems that use external holding mechanisms, the motor is supplied without a blocking brake, which removes brake drag during continuous rotation. Rotor balance conforms to standard balancing so vibration remains within normal limits when the assembly runs at rated speed. A molded connector on the housing provides a compact cable interface and keeps wiring secure at the motor.
