Product Description:

The MDD090B-N-030-N2L-110PL2 is an AC synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is supplied as a motor for digital drive controllers, where it converts precisely modulated current into controllable torque and speed for axes in packaging machines, handling modules, or printing presses. The motor fits automation requirements that demand fast acceleration, repeatable positioning, and closed-loop velocity control, making it a common actuator in multi-axis systems coordinated by Rexroth drives.

It reaches a nominal rotational velocity of 3000 rpm, allowing mechanical cycles to be synchronized with typical inverter operation. At standstill, the electromagnetic system delivers a continuous torque of 7.2 Nm, so the axis can hold static loads without overheating. A blocking brake is integrated, and its holding torque of 11.0 Nm secures vertical or overhung loads when power is removed. Precise physical alignment is simplified by the 110 mm centering diameter, while smooth running is supported by standard dynamic balancing. Its standard housing permits fanless convection cooling inside typical machine enclosures. Power and feedback cables exit to the left through a single plug connector, reducing cabinet depth.

Digital control accuracy is enhanced by the built-in digital servo feedback encoder that sends rotor position data to the drive without an external transducer. The mechanical interface follows size code 090, and the B-length stator provides thermal mass appropriate for mid-range duty cycles without adding unnecessary weight. A molded shaft seal helps keep dust away from the bearings and limits lubricant escape, while the keyed shaft profile, identified as a keyway, transmits torque to couplings with positive engagement. The single-ended shaft design omits a side B extension, allowing the motor to sit flush against gearheads or belt pulleys in compact assemblies.
