Product Description:
The MDD090B-N-040-N2M-110GA0 is a three-phase synchronous motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it provides tightly regulated torque and speed in servo loops for automated transfer stations, indexing tables, and similar industrial axes. Through permanent-magnet excitation and internal position feedback, the unit supports rapid acceleration and repeatable positioning during cyclic motion. This makes it suitable for axes that must start, stop, and reverse direction frequently while maintaining stable motion control.
Balancing is standard, so vibration levels remain controlled without additional counterweights. The centering pilot measures 110 mm, giving an accurate seating reference for flanges or gearboxes. Power and signal lines exit on Side A through a modular connector, which helps keep cable routing orderly in compact machine layouts. At standstill, the motor can deliver 7.2 Nm of continuous torque, which supports inverter matching and thermal planning. Under rated excitation, it reaches a nominal speed of 4000 rpm, allowing direct coupling to moderate-inertia loads while still providing a wide operating range for dynamic positioning. The 090 frame with B length keeps the motor compact enough for installation in confined machinery spaces.
Feedback is provided by an integrated multiturn absolute encoder, and Digital servo feedback (DSF) transmits position data to the drive across multiple revolutions. Because the feedback system is built into the motor, the controller can monitor rotor position continuously during motion and after direction changes. The motor is supplied without a blocking brake, so vertical or suspended loads require external holding force when power is removed. The output uses a plain shaft with a shaft seal, which helps protect internal bearings from coolant splash and dust ingress. Side B remains closed, and the housing is not fitted with a second connection point on that end.
