Product Description:

The MDD090B-N-040-N2M-130PR0 is a motor for digital drive controllers engineered by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for servo axes that require exact speed regulation and repeatable positioning in industrial automation, including handling systems, transfer units, and automated machine tools. The unit corresponds to motor size 090 and length code B, and the housing and rotor use the standard balancing arrangement for this motor line. A shaft seal helps protect the bearings from airborne contaminants, and the motor has a single shaft end without an auxiliary output, which keeps the drive end straightforward for standard coupling arrangements.

During stationary loading, the motor can deliver 7.2 Nm of continuous torque, providing stable holding force for vertical or high-inertia axes during steady operation. Once motion commands are issued, the rotor can reach a rated speed of 4000 rpm, which suits medium-power spindles and pick-and-place gantries. Rotor position is captured by an integrated multi-turn absolute encoder, and the signal is transmitted through digital servo feedback so the drive controller can maintain precise phase alignment under changing loads. All power and feedback conductors exit on the right side of the housing, which can simplify cable routing where installation space is limited or machine guards restrict cable bend radius.

The motor uses a 130 mm centering flange to support accurate alignment with gearboxes or mounting plates. Electrical connections are made through a sealed connector that helps protect the terminal area from shop-floor contamination. The design is supplied without a blocking brake, so position holding after power loss must come from the drive or a separate mechanical lock. The output shaft has a keyway for direct torque transfer to couplings or similar driven elements.
