Product Description:

The MDD090C-N-020-N2L-110PB1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It serves as the rotary element in digital drive controller assemblies, translating commanded current into mechanical motion for machining centers, handling modules, and conveyor axes. Built for digital drive controllers, it delivers controlled torque and speed in a 090 frame with a standard housing, a keyed shaft end, and no secondary shaft on side B. This arrangement supports direct coupling to common transmission elements while keeping the motor body compact enough for densely packed machine layouts.

During position holding or low-speed feed, the motor can generate a continuous stall torque of 10.4 Nm, and it reaches its rated operating velocity at 2000 rpm. An integrated blocking brake provides 6.5 Nm of holding torque so suspended or vertical loads can remain secure when drive power is removed. Mounting is centered by a 110 mm pilot diameter for accurate alignment with machine flanges or gearboxes, which helps reduce coupling misalignment and bearing stress. Position data is supplied through digital servo feedback (DSF), which gives the controller the rotor information needed for closed-loop torque and speed regulation. That feedback arrangement supports stable motion control during acceleration, deceleration, and steady-state operation.

Cabling exits on Side B, which can simplify routing when drives are installed in a row or where cable trays approach from the rear. A keyed power and encoder connector provides a secure interface and helps protect signal quality under vibration. The rotor is balanced to a standard grade, and the motor uses length code C for a mid-size housing within the MDD range. A shaft seal helps retain lubricant at the front bearing, while the output shaft uses a keyway profile for direct coupling to pulleys, hubs, or similar machine elements.
