Product Description:

The MDD090B-N-040-N2L-110GL0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is supplied for use with digital drive controllers, where it converts commanded electrical power into precise rotary motion for machine tools, packaging lines, and material-handling axes. Its synchronous design supports controlled speed and position behavior when paired with a compatible servo amplifier. The unit uses the 090 frame size with a B length code, giving a mid-range footprint that fits standard mounting patterns in modular automation cells.

The mechanical interface uses a centering diameter of 110 mm, allowing the flange to seat accurately against gearboxes or adapter plates. Power and feedback cables exit on the machine's left side, and the motor uses a plug-in connector interface for straightforward cable attachment. At standstill, it can deliver 7.2 Nm of continuous torque for positioning duties. During operation, the rotor can reach a nominal speed of 4000 rpm, which supports high throughput with low-inertia loads. For applications that use external holding devices, the unit is supplied without a blocking brake, which reduces mass and removes brake-related wear components.

In closed-loop service, the motor sends position data to the drive through digital servo feedback, allowing the controller to adjust current in real time and maintain commanded motion profiles. The output uses a plain shaft with no keyway, and the rear face has no side B extension, which helps simplify direct coupling arrangements. This shaft arrangement is suited to shrink-fit or clamp-style couplings that do not require a keyed interface. A front-mounted lip seal is supplied with a shaft seal to help block lubricant migration and contaminant entry. Internal components are balanced to the standard grade to limit vibration during rated operation.
