Product Description:

The MDD090C-N-040-N2M-110PA2 synchronous motor is manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for coupling with digital drive controllers, the unit transforms drive current into regulated mechanical motion for automated positioning, conveying, or packaging axes within industrial machinery. This arrangement allows the controller to regulate axis movement while the motor supplies rotary output to the machine. Its housing and rotor are factory balanced to a standard quality grade, allowing vibration-controlled operation without additional field adjustment.

Continuous torque at standstill is 10.4 Nm, so the motor can supply that torque indefinitely without exceeding thermal limits when blocked. A nominal speed of 4000 rpm is the rated mechanical output velocity under sinusoidal excitation, so speed loops can be tuned around that value. During deceleration or emergency stops, the internal blocking brake can hold the shaft with 11.0 Nm of static torque after power is removed. This helps prevent load drift when the axis must remain in place at standstill. The motor has size code 090 and length code C, which identify the frame and motor length used for this model. A multiturn absolute encoder and digital servo feedback supply position data directly to the drive.

A centering diameter of 110 mm aligns the flange with gearboxes or mounting plates, and it helps locate the motor accurately during mounting. The ground shaft end is machined with a keyway to transmit torque through standard hub keys. Power and feedback conductors exit on Side A through a sealed connector, which keeps the electrical interface compact inside the machine frame. A dedicated shaft seal helps keep coolant or lubricants away from the bearings during operation. The motor has a single shaft end, so there is no secondary shaft extension on the opposite side.
