Product Description:

The MDD090A-N-030-N2M-130GR0 is a synchronous servo motor from the MDD Synchronous Motors series produced by Bosch Rexroth Indramat. Designed for digital drive controllers, it converts commanded current into precise rotary motion for positioning axes, pick-and-place heads, and other automated machinery. The unit’s frame, feedback electronics, and winding layout follow series standards so it can be used with compatible drives in multi-axis systems. Its role in industrial automation is to provide repeatable torque across its speed range while reporting exact shaft position to the control loop.

Its continuous stall torque is 3.7 Nm, allowing low-inertia loads to be held without additional gear reduction. During operation, the rotor can reach a nominal speed of 3000 rpm, giving a direct relationship between command frequency and mechanical speed for fast cyclic tasks. Mounting is simplified by a 130 mm centering diameter that aligns the housing concentrically to machine frames, and the rotor and fan are balanced to the standard grade to limit vibration. Power and feedback leads exit on the right side through a sealed connector, a layout that matches cable trays running along the drive cabinet.

The built-in integrated multiturn absolute encoder supplies position data over digital servo feedback (DSF) so the controller can close velocity and position loops without external sensors. The motor has no blocking brake, so the machine must rely on drive torque or mechanical locks to secure the axis when power is removed. A plain shaft is provided in the standard single-ended configuration. It is protected by a shaft seal that limits lubricant escape and helps keep airborne contaminants away from internal components. This motor includes an IP65 protection rating and a Class F insulation rating. The ambient operating temperature is between 0-40 degrees Celsius.
