Product Description:

The MDD090A-N-040-N2M-130PA2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it supplies rotary motion for coordinated speed and position control in industrial automation lines, material-handling axes, packaging stations, and similar motion systems. The motor converts commanded current into controlled shaft rotation so synchronized axes can follow programmed motion with repeatable response. It uses the 090 frame format with the A length code, giving it a compact stator stack and a standard housing that mounts directly to machinery without additional adapters.

The rated operating speed reaches 4000 rpm, giving the axis headroom for rapid indexing while staying below the critical frequency of typical mechanical transmissions. At standstill, the motor can deliver 3.7 Nm of continuous torque during static holding tasks such as tensioning or vertical load support. For emergency stops and power-off retention, a blocking brake produces up to 11.0 Nm of torque to lock the shaft without external clamping devices. Mechanical centering is handled by a 130 mm pilot diameter that aligns the flange to the machine frame. Power and sensor leads exit on the A-side, and the mating style is a sealed industrial connector that keeps wiring secure in enclosed equipment.

Signal quality is maintained through digital servo feedback (DSF), which lets the controller read rotor position every cycle for high-bandwidth current loops. The position source is an integrated multiturn absolute encoder, so the axis can retain position information after shutdown. This feedback arrangement supports closed-loop regulation without a separate external position transducer. A shaft with a keyway accepts standard couplings, and an integral shaft seal helps prevent oil or dust from migrating along the journal into the stator cavity. Standard dynamic balancing reduces residual vibration, which supports stable motion in printing, pick-and-place, dosing, and other precision equipment.
