MDD071A-N-040-N2S-095PB2
The Bosch Rexroth Indramat MDD Synchronous Motors series includes the MDD071A-N-040-N2S-095PB2, an AC servo motor for use with digital drive controllers in automated machinery. The unit converts electrical command signals into controlled mechanical rotation, allowing accurate positioning and velocity control in pick-and-place stages, packaging lines, and material-handling axes. It is built with a standard housing and an integrated blocking brake so the motor can hold a load when power is removed. This combination makes the motor suitable for compact motion systems that need precise response and dependable stopping behavior.
A centering pilot of 95 mm locates the motor concentrically against gearboxes or adapter flanges, which helps keep shaft alignment consistent during installation. Power and feedback connections exit on Side B, so the front of the machine can remain clear where space is limited. The rotor can reach 4000 rpm, supporting fast cycle rates in high-speed automation tasks. With length code A, the motor uses the shortest housing in this frame size, which helps reduce overall mass and inertia. Frame size 071 places the unit within a common mounting format for this motor platform.
Torque at zero speed is rated to 2.2 Nm, giving stable performance during indexing moves and controlled holding at standstill. When the axis must remain fixed after power is removed, the integrated blocking brake provides 6.5 Nm of static torque to resist load drift. Position information is returned through digital servo feedback, allowing electronic commutation and closed-loop speed and position control. The shaft uses a keyway for secure torque transfer to couplings and driven elements. A shaft seal is fitted at the output end to help keep contaminants away from the front bearing during routine machine operation.
