Product Description:

Bosch Rexroth Indramat's MDD090A-N-030-N2M-130PA1 is an AC synchronous servo motor in the MDD Synchronous Motors series. Designed for direct pairing with digital drive controllers, it converts precisely metered stator current into rotary motion for indexing tables, gantry axes, and tool spindles. Permanent-magnet excitation supports high torque density, while the 90 mm frame and A-length stator help the motor fit compact machine layouts. This combination suits applications that need accurate acceleration, repeatable positioning, and stable speed control over frequent duty cycles.

The motor can sustain 3.7 Nm of continuous standstill torque, which indicates the thermal limit during holding or low-speed feed operation. It reaches a nominal mechanical velocity of 3000 rpm, providing a balance between speed range and feedback resolution for servo loops driven by PWM inverters. A blocking brake produces up to 6.5 Nm of static torque to secure vertical loads whenever power is removed. Mechanical centering relies on a 130 mm pilot diameter that aligns the flange to adjoining frames and helps reduce radial runout. Feedback is transferred through digital servo feedback, allowing the controller to close position and velocity loops with fast updates and stable motion response.

An integrated multi-turn absolute encoder supplies position information immediately after power-up, so the axis does not need an external homing move before normal operation. Power and signal connections are routed on side A through a shielded connector, which helps keep cable routing orderly in compact installations. Torque is transmitted by a shaft with a keyway, and a shaft seal helps keep coolant and fine debris away from the front bearing cavity. Standard dynamic balancing and a single-ended shaft support smooth rotation, while the general-purpose housing and 090 frame size suit repetitive industrial motion.
