Product Description:

The MDD090A-N-040-N2M-130PR2 is a synchronous AC servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts commanded stator currents into precise rotor movement for positioning, indexing, and speed-regulated duties in automated machinery and production lines. Its standard housing and balancing allow integration on general-purpose servo axes, while the built-in blocking brake secures vertical or safety-critical loads when paired with compatible drive modules.

Its nominal speed reaches 4000 rpm, meaning the rotor can sustain 4000 revolutions per minute under rated voltage and load. At standstill, the motor delivers 3.7 Nm of continuous torque, providing static force for holding or low-speed feed operations without thermal overload. Position data are produced by an integrated multiturn absolute encoder, which sends multi-revolution angle information to the controller for closed-loop accuracy. During power-off, the fitted brake applies 11.0 Nm of holding torque to keep the axis locked. A machined keyway on the shaft transfers torque positively to couplings or pulleys and helps prevent slippage during acceleration.

Installation uses a flange with a diameter of 130 mm, which supports accurate seating against gearboxes or machine frames. Power and feedback leads exit on the right side, which can simplify cable routing where right-hand connector orientation is preferred. Control data travel over Digital servo feedback (DSF), enabling closed-loop operation and automatic parameter recognition. A radial shaft seal is fitted at the output end to help block dust, coolant, and lubricant migration. The motor also uses the A length code and a plug-in connector interface for compact installation in multi-axis assemblies.
