MDD071A-N-040-N2T-095GR1
The MDD071A-N-040-N2T-095GR1 is a synchronous AC servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it provides rotary motion and position feedback to closed-loop axes in packaging machines, handling modules, and similar equipment. Its integrated feedback functions allow direct pairing with compatible Rexroth drive amplifiers, so the controller can regulate speed and position with high repeatability. This arrangement supports accurate starts, stops, and direction changes in automated systems that depend on stable servo response during continuous production.
This model reaches a nominal speed of 4000 rpm, which allows high continuous operating speed in dynamic axis applications. A continuous standstill torque of 2.2 Nm allows the motor to hold a commanded position at zero speed under suitable load conditions. Accurate mechanical registration to a gearbox or machine plate is supported by the 95 mm centering diameter. Power and feedback leads exit on the right side, and a single connector combines phase, brake, and sensor conductors in one interface. Closed-loop control is supported through digital servo feedback, which sends rotor position data to the drive so commanded motion can be tracked with low following error. Standard balancing supports smooth running in general-purpose installations, while the A length code indicates the shortest housing length in the 071 frame group.
A blocking brake supplies 3.0 Nm of holding torque to secure loads when power is removed. Position retention across multiple revolutions is provided by an integrated multiturn absolute encoder, so the axis can retain position information after shutdown. The motor uses a plain shaft without a keyway, which suits friction-locked couplings and helps avoid stress concentration at the shaft surface. A shaft seal is fitted to limit the movement of contaminants and lubricant around the shaft entry point. The housing follows the standard series configuration, and the 071 size supports compact installation where machine spacing is limited.
