Product Description:

The MDD090C-N-040-N2L-110PA0 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed to pair with digital drive controllers, the unit converts electrical commands into controlled rotary motion for positioning, indexing, and continuous-speed tasks inside automated machinery and production equipment. Its mechanical envelope follows the 090 frame size, and the C length code corresponds to the active stack depth used for mid-range torque demands. Combined with the series’ feedback and sealing features, the motor provides a compact actuator suited to general industrial automation tasks.

The motor’s centering pilot measures 110 mm, allowing accurate alignment with gearbox flanges or mounting plates and limiting radial runout. At standstill, the electromagnetic system can exert 10.4 Nm of continuous torque, supplying stable holding force during low-speed processes. Under rated excitation, it reaches a nominal shaft velocity of 4000 rpm, giving a balance between dynamic response and thermal loading for medium-inertia loads. All power and feedback conductors exit on Side A of the housing, and an industrial connector interface simplifies plug-in wiring during installation and service. Internal rotor balancing is specified as standard, so no special counterweights are required during installation.

Closed-loop motion is achieved through digital servo feedback that communicates precise rotor position to the drive in real time. A machined keyway on the output shaft transmits torque without slip, while the front bearing region is protected by a shaft seal, limiting the ingress of lubricants and particulates. The unit is supplied without a blocking brake, so external brakes or drive-held torque must secure vertical axes when power is removed. Standard housing geometry, the single-ended shaft designation, and the 090 frame code support use in machine layouts already sized for this MDD motor format.
