Product Description:

The MDD071B-N-040-N2T-095PB1 servo motor is manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Intended for use with digital drive controllers, it converts regulated current into rotary motion for positioning, feed, and auxiliary tasks in automated machinery. The motor delivers controlled torque response that supports compact axis layouts and repeatable motion in industrial systems. Its format is well suited to machines that need accurate starts, stops, and holding behavior from a compact servo package.

At standstill, the motor can deliver a continuous torque of 4.4 Nm, allowing it to maintain load at zero speed without excessive heating under rated conditions. During operation, its rotor reaches a nominal speed of 4000 rpm, which suits fast positioning cycles and other high-speed axis movements. Mounting accuracy is supported by a centering diameter of 95 mm, which helps align the motor with gearboxes or adapter plates. Position information comes from an integrated multi-turn absolute encoder, and the signal is transmitted through digital servo feedback (DSF) for closed-loop control. This feedback arrangement lets the drive track shaft position over multiple revolutions while maintaining stable speed regulation.

Power and feedback conductors exit on side B through a circular connector, which helps route cabling away from the load end of the motor. A blocking brake rated at 3.0 Nm is integrated to hold vertical or indexing axes when drive power is removed. The output uses a keyway shaft with a shaft seal, so torque can be transmitted through keyed couplings while helping keep contaminants away from the bearing area. The motor has size code 071 with length code B and uses a single shaft end toward the load side. Standard dynamic balancing supports smooth running during normal machine operation.
