MDD071A-N-040-N2S-095PL2
The MDD071A-N-040-N2S-095PL2 belongs to the MDD Synchronous Motors series produced by Bosch Rexroth Indramat. It is a brushless AC servo motor intended for direct pairing with compatible digital drive controllers to create closed-loop positioning axes in automated machinery. As a motor for precise industrial motion, it converts commanded current into rotational torque so that packaging stations, pick-and-place units, or light machining spindles can follow programmed speed and position profiles.
The mechanical interface centers on a 95 mm centering diameter that aligns the flange to mounting fixtures and helps keep radial runout low. At standstill, the rotor can deliver 2.2 Nm continuously, allowing static holding or slow feed moves without overheating. During operation, the shaft reaches a nominal velocity of 4000 rpm, matching applications that need moderate speed with high repeatability. Rotor position is reported through Digital servo feedback (DSF), giving the drive high-resolution data for torque vector control and electronic commutation. A blocking brake is integrated, and its rated holding torque of 6.5 Nm secures vertical loads or maintains position when power is removed.
Cabling enters on the left side through a keyed power and signal connector, so panel layouts can be planned around a single service corridor. The solid shaft is machined with a keyway, enabling quick coupling to pulleys or gear sets without additional adapter parts. Contamination ingress is limited because the front bearing region is supplied with a shaft seal, supporting installation in environments that contain coolant mist or dust. The motor size is 071, and the A length code indicates the shortest stator stack in this frame, reducing mass and inertia for fast acceleration of light loads while still fitting the standard housing and balancing class used in the series.
