Product Description:

The MDD090B-N-040-N2M-110PB2 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers in applications that require fast positioning and stable speed regulation. In automated packaging, material handling, and assembly equipment, the motor converts electrical drive commands into controlled rotary motion for repeatable axis movement. Its synchronous design also supports responsive acceleration and accurate following of changing motion commands during cyclic machine operation. This makes it appropriate for feed axes, indexing tables, and transfer mechanisms that must track commanded motion without lag.

Its centering pilot measures 110 mm, allowing accurate alignment with gearboxes or mounting flanges during installation. Accurate centering helps maintain alignment between the motor shaft and driven machine elements, which can reduce unnecessary mechanical stress. At standstill, the motor can deliver 7.2 Nm of continuous torque, which supports static loads without excessive heat rise. During normal operation, the rotor reaches a nominal speed of 4000 rpm, which suits automation cycles that require fast indexing and short travel times. When power is removed, an internal blocking brake applies 11.0 Nm of holding torque to secure the shaft. Position information is returned through digital servo feedback, and the integrated multi-turn absolute encoder provides position data over multiple revolutions so the controller knows rotor angle immediately after power-up.

Electrical and mechanical interfaces are arranged at the rear of the stator, where the power and feedback connectors point toward side B. The cables attach through a keyed connector, which helps prevent incorrect mating during installation. The motor uses a standard housing with front bearing protection and a shaft seal to support enclosed machine environments. Torque is transferred through a shaft with a keyway, which allows coupling to pulleys, hubs, or similar drive elements. The shaft layout is single-ended, so there is no second output at the rear, and the rear-mounted connections can simplify cable management when the motor is installed close to guards or machine frames.
