Product Description:

The MDD071A-N-040-N2T-095GL2 is a brushless synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts controlled electrical input into rotational motion. That motion can be coordinated with position loops in automated machinery and handling stations, making the unit suitable for compact servo axes that require accurate speed control and repeatable positioning.

This unit delivers a continuous standstill torque of 2.2 Nm, which supports moderate load requirements while the rotor is locked. Its nominal operating speed is rated at 4000 rpm, giving the drive a broad velocity range before field weakening becomes necessary. A standard dynamic balancing class helps limit residual vibration, and the symmetrical housing profile supports installation where space is limited. The centering collar measures 95 mm, so the flange fits matching pilot diameters on gearboxes or mounting plates. Size code 071 and length code A indicate a compact build depth. Power and feedback are routed on the left side through a keyed circular connector, which helps keep cable routing orderly inside tight enclosures. The shaft is plain and is supplied without a side-B extension, so it can be used with clamp or collet couplings.

Position retention during power-off is provided by a blocking brake that applies 6.5 Nm of static torque, which helps prevent axis drift on vertical or overhung loads. Motion accuracy is supported by digital servo feedback, which sends high-resolution rotor data to the drive for closed-loop control. That data comes from an integrated multiturn absolute encoder, so the axis can report position immediately after startup without a reference move. Contamination ingress is limited by a dedicated shaft seal, which helps protect the bearing area when the motor is installed in splash-prone locations. Standard housing and balancing features support precise motion in space-saving assembly and material transport systems.
