Product Description:

The MDD090B-N-040-N2M-130GA2 is a servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for direct attachment to a digital drive controller, this unit turns electrical commands into precise rotary motion for positioning, feed, or indexing tasks in automated machinery. Its standard housing and compact frame enable installation inside machine cabinets, while the connector-based interface supports quick exchange during maintenance. It serves in servo loops where high responsiveness and repeatable accuracy are required and is often coupled directly to ball screws or belt pulleys without intermediate gearing.

At standstill, the motor can deliver a continuous torque of 7.2 Nm, allowing it to hold loads without overheating when commanded current is maintained. Once the axis accelerates, the rotor reaches a nominal speed of 4000 rpm, a value matched to medium-speed machining and handling duties. For emergency stopping or power-off locking, an internal blocking brake supplies up to 11.0 Nm of static torque. Mechanical centering onto the machine flange is guided by a 130 mm centering diameter that constrains radial runout. Positional data is returned through digital servo feedback (DSF), so the associated controller receives high-resolution signals for commutation and diagnostics. The motor has size 090, length code B, a standard housing, and a single connector plug.

The feedback chain is complemented by an integrated multi-turn absolute encoder that stores shaft position across power cycles, eliminating homing procedures after each startup. All power and signal conductors exit on side A, which simplifies cable routing along linear axes. A plain shaft is supplied, and a shaft seal protects the bearing seat against coolant spray or airborne particles. Standard dynamic balancing minimizes residual vibration, and the absence of a shaft end on side B shortens the overall length, easing enclosure integration.
