Product Description:

The MDD090A-N-040-N2M-110PR0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it supplies rotary motion for positioning and velocity-controlled axes in automated machinery such as packaging stations, handling units, and indexing devices. A standard housing and standard dynamic balancing allow the unit to be mounted in compact machine assemblies without extra counterweight or support hardware. That layout helps the motor fit common servo applications where smooth rotation and predictable mechanical alignment are important.

This motor delivers a continuous standstill torque of 3.7 Nm, giving stable holding and low-speed capability when paired with a compatible controller. Under rated conditions it can spin at 4000 rpm, so high cycle rates are possible without oversizing the transmission on fast indexing or feed axes. Installation centers on a 110 mm centering diameter that aligns the flange with the machine frame for accurate mounting. Cabling uses right-side cable entry because the power and feedback plugs are positioned on that side, and a single connector interface keeps the connection layout compact at the motor body. The shaft uses a keyway profile for positive drive engagement, and the shaft seal helps block oil or coolant from entering the bearing area. The motor is supplied with a standard single shaft end, which suits direct coupling to pulleys, gearboxes, or other driven elements.

Feedback and control signaling rely on digital servo feedback from an integrated multiturn absolute encoder, enabling the controller to read true rotor position after power is restored and maintain closed-loop motion control through operating cycles. The motor has length code A, which is the shortest stator stack in this frame, and frame size 090 for compact machine layouts where installation space is limited. The unit is supplied without a blocking brake, so braking or load holding must be provided by an external mechanism on vertical or gravity-loaded axes. This arrangement is suitable for applications that use external holding devices or depend on drive-controlled torque during planned stops.
