Product Description:

Bosch Rexroth Indramat manufactures the MDD090A-N-030-N2M-130PB1 in the MDD Synchronous Motors series. This synchronous motor is intended for use with digital drive controllers, allowing closed-loop speed and torque regulation in automated machinery and material-handling axes. By combining the mounting interface, feedback system, and electrical connections in one assembly, the unit supports compact servo installations where accurate motion control and straightforward integration are required.

The flange has a centering diameter of 130 mm, which aligns the motor accurately with the mating machine surface. Power and feedback conductors exit on Side B, and the connector interface allows the cable set to be detached without removing the motor body. At standstill, the rotor can deliver 3.7 Nm of continuous torque, which is the level the windings can maintain with the shaft locked under normal thermal conditions. Position information is provided by an integrated multiturn absolute encoder, while Digital servo feedback (DSF) supplies the drive with the signals needed for precise velocity control. The rotor uses a standard balancing grade, and the housing is the standard non-ventilated version that releases heat through the mounting surface rather than through forced airflow.

An integrated blocking brake rated at 6.5 Nm locks the shaft during power-off conditions and helps prevent axis drift on vertical applications. During operation, the motor reaches a nominal speed of 3000 rpm, giving the drive a suitable operating range for matched transmission components. Torque is transmitted through a shaft with a keyway, and the front bearing area is protected by a shaft seal that helps limit lubricant leakage and the entry of contaminants. The size 090 housing with length code A keeps the motor compact, and the standard shaft end does not include a rear extension, which helps conserve installation space in closely packed machine layouts.
