Product Description:
The MDD090A-N-030-N2L-110PR0 is an AC synchronous motor built by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Designed for use with digital drive controllers, it serves as the electromechanical actuator in numerically controlled gantries, tool spindles, and material-handling axes. The motor supports closed-loop speed and position regulation in applications that require accurate rotary motion. That operating role makes it suitable for machine tools and automation systems that need stable response during changing load conditions.
The motor’s mechanical interface follows a standard balancing grade to minimize residual vibration, and its centering pilot measures 110 mm for precise flange alignment. Power and feedback leads exit on the right side of the housing through a compact connector, which helps simplify cable routing. A standard cast housing encloses the stator, while a shaft seal keeps lubricant inside the bearing zone and helps limit particle ingress. The shaft is supplied only on the drive end, so no side-B extension is included. The single-ended shaft layout leaves the non-drive end closed, which helps keep the housing compact and avoids an unused output extension. During standstill operation, the unit can deliver 3.7 Nm of continuous torque, but it is supplied without a blocking brake, so external holding measures are required when the load must remain fixed.
Control integration uses the digital servo feedback system, which returns high-resolution rotor position data to the drive for closed-loop operation. The feedback channel lets the controller track rotor angle continuously, which supports smooth commutation and stable response at low and high speeds. The motor has a nominal speed of 3000 rpm, and the 090 frame size with compact length code A helps provide a favorable inertia profile for rapid acceleration. The ground shaft uses a keyway, so torque can be transmitted with standardized hub hardware. This arrangement supports accurate positioning and speed control on dynamic axes.
