Product Description:

The MDD090A-N-040-N2L-110GB1 is a brushless synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for digital drive controllers and converts commanded current into regulated rotary motion for positioning axes in packaging, printing, and material-handling machines. The brushless design supports responsive closed-loop operation while reducing the wear associated with contact-based commutation components. This makes the unit suitable for repeatable start-stop duty where speed control and position accuracy must remain stable across frequent motion cycles.

At a nominal speed of 4000 rpm, the motor supports rapid positioning cycles while maintaining a continuous standstill torque of 3.7 Nm for static load support. A blocking brake rated at 6.5 Nm holds the shaft during power-off states, which is useful on vertical or suspended axes. Position data is returned through digital servo feedback (DSF), allowing the controller to close velocity and position loops with high resolution. The digital feedback format helps preserve signal quality over typical machine cable lengths and supports precise controller correction when load conditions change. A centering diameter of 110 mm provides a rigid fit to machine frames and helps reduce runout during acceleration.

Power and feedback conductors exit on side B through a sealed connector, which keeps cable routing away from moving machine elements. The rotor and stator use size 090 with compact length code A, giving the motor a short overall body for tight installation spaces. A shaft seal is installed to limit ingress, and the output uses a plain shaft for direct attachment of couplings or pulleys. This shaft arrangement is useful where a simple clamping hub or belt pulley is preferred. The standard enclosure profile and standard dynamic balance support steady operation in general industrial motion systems.
