Product Description:

The MDD090A-N-030-N2M-110PA1 is produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers. The motor converts commanded current into regulated mechanical motion and supplies precise torque and speed for positioning axes, conveyors, and other automated equipment on the factory floor. This type of motor is suited to applications that need accurate speed regulation during acceleration, running, and stopping. It can also support repeatable positioning when paired with a compatible feedback-capable drive.

At a continuous standstill torque of 3.7 Nm, the rotor can hold loads without drift when commanded to zero speed. During dynamic operation, the shaft reaches a nominal speed of 3000 rpm, allowing direct coupling to gearless transmission stages. Power and feedback conductors exit on Side A, where they connect through a plug-in connector. Position data return to the drive through digital servo feedback, and this arrangement keeps the feedback path inside the motor package. Grouping the electrical connections on one face can help keep cable routing orderly in compact machine spaces. The motor uses length code A and size 090 for a compact installation envelope, and a shaft seal helps protect the bearings from spray and dust.

For static holding or emergency stops, the integrated blocking brake supplies 6.5 Nm of torque. The centering diameter of 110 mm aligns the flange with adjoining machine frames, while torque is transferred through a keyway shaft for positive mechanical engagement under bidirectional loads. Rotor position is monitored by an integrated multiturn absolute encoder, which gives the drive an absolute reference after power loss. The brake engages automatically when power is removed, and the motor uses a standard shaft end without a side-B extension. The encoder and brake combination supports controlled holding and immediate position recognition after a restart. Standard dynamic balancing and the sealed housing help maintain smooth rotation over the service life.
