Product Description:

The MDD090A-N-020-N2L-130GB1 is a synchronous AC servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it converts inverter current into precise rotation for closed-loop speed and position control on conveyors, pick-and-place devices, and other automated axes. Its synchronous design helps the drive maintain stable torque response during acceleration, deceleration, and repeated positioning moves.

Rotating parts use standard balancing, so extra counterweights are unnecessary during coupling. A 130 mm centering diameter aligns the frame to mounting flanges for concentric operation. Power and feedback exit through a single connector, which keeps the cable interface compact. The motor sustains 3.7 Nm of continuous torque at standstill, with the limit determined by coil heating under natural convection. Position data are returned through Digital servo feedback (DSF), allowing the drive to correct speed and angle with high precision. Size code 090 and length code A give the motor a compact stator stack that fits crowded machines, while the standard housing supports predictable heat dissipation. An integral shaft seal helps protect the bearings from dust and oil during normal operation.

The motor includes a blocking brake that clamps the rotor when de-energized. Its holding capability reaches 6.5 Nm, which helps prevent drift on vertical or suspended loads. Electrical and feedback connectors are oriented toward Side B, so clearance is needed on that face for cable routing. During motion, the rotor can reach 2000 rpm, a nominal speed that suits commonly used screw drives and gear stages. The output uses a plain shaft without keys or splines, which simplifies coupling to backlash-free clamping hubs. The shaft end is present only on the drive side, leaving the rear clear for feedback hardware and keeping the non-drive end unobstructed.
