Product Description:

The MDD090B-N-030-N2M-110PR0 synchronous motor is produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts drive current into controlled rotation for axes that require precise speed and position control in industrial automation. Its standard housing and dynamic balance grade permit direct installation in packaging lines, material-handling cells, and machining centers, while the shaft is limited to side A to keep the encoder region clear.

It delivers a continuous standstill torque of 7.2 Nm, meaning the rotor can sustain that load indefinitely without exceeding thermal limits. Under rated excitation, the shaft reaches a nominal speed of 3000 rpm, aligning electrical input with mechanical output. Mounting is centered by a 110 mm pilot diameter that aligns the flange with adjacent machine components. Power and feedback cables exit on the right side because the motor’s connector block is oriented accordingly, helping grouped motors follow an orderly routing path inside the machine. The output shaft uses a keyway, so pulleys or couplings can lock positively for torque transmission. Electrical terminations are made through a circular connector, and the unit uses the size 090 frame with a standard housing finish.

Feedback is provided by an integrated multi-turn absolute encoder that retains position data through multiple revolutions. Its signals return over digital servo feedback (DSF), giving the drive controller high-resolution information for closed-loop regulation. The length code B identifies the second-longest stator in this frame, adding thermal mass compared with the shorter version. A circumferential shaft seal helps protect the bearing journal from coolant spray and dust. The motor is supplied without a blocking brake, so holding tasks must rely on external braking hardware or servo torque.
