Product Description:

The MDD090B-N-020-N2M-130PA0 is produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is an AC servo unit intended for digital drive controllers where precise position and speed regulation are required on packaging lines, material-handling axes, and general machine-tool spindles. When paired with matching drives, it serves as a closed-loop motion element that converts commanded current into accurate mechanical rotation while maintaining consistent torque under varying load conditions and rapid speed changes.

The motor can deliver a continuous standstill torque of 7.2 Nm, which is the sustained load it can hold without overheating while stationary. During operation it reaches a nominal rotational velocity of 2000 rpm, which gives a practical base speed for controller tuning and common gearbox selection in automated equipment. Mechanical centering is supported by a 130 mm pilot diameter so the housing aligns concentrically with the mounting flange. Power, brake, and feedback leads exit on Side A of the frame, simplifying cabinet layout when the machine design expects cabling from one direction. Electrical terminations are handled through a sealed connector, enabling quick exchange and minimizing wiring errors during installation or service.

The output shaft uses a keyway profile to transmit torque to couplings without slip, and a shaft seal blocks lubricant migration into the stator chamber for contamination control. Position data is fed back over digital servo feedback, allowing the drive to close high-resolution loops without external sensors during positioning or speed control. An integrated multi-turn absolute encoder stores revolutions even when power is removed, so homing is unnecessary after maintenance cycles. Because the design is supplied without a holding brake, applications that need static load retention must use mechanical locks or drive torque during power-off states.
