Product Description:

The MDD090A-N-030-N2M-110GA1 is a synchronous servo motor produced by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into precise rotary motion for positioning and speed control in automated machinery. An integrated multi-turn absolute encoder returns high-resolution feedback to the controller, so coordinated axes can retain position information across power cycles and maintain stable commutation during operation.

The stator face locates against a centering shoulder with a diameter of 110 mm, which supports accurate alignment during mounting. The motor provides a continuous standstill torque of 3.7 Nm, and its nominal speed reaches 3000 rpm for general-purpose motion tasks. A rear-mounted blocking brake delivers 6.5 Nm of holding torque to keep the shaft from moving when power is removed. Power, brake, and feedback conductors exit on Side A through a single keyed connector, which keeps cable routing straightforward and keeps the electrical interfaces grouped at one end of the housing. Digital servo feedback supplies absolute position data directly to the drive and supports electronic commutation without separate Hall sensors.

The output uses a plain shaft, which suits clamp-style couplings and other keyless connections. A shaft seal is fitted at the shaft exit to help keep contaminants away from internal bearing areas and to limit lubricant migration into the surrounding machine space. The motor has length code A, which keeps the housing compact because no side-B shaft extension is provided. Its frame size is 090, so the flange dimensions match the mounting pattern used for this motor class. The standard housing and balancing arrangement help keep vibration low at the machine interface during normal servo operation.
