MDD071B-N-030-N2T-095GR0
The MDD071B-N-030-N2T-095GR0 is a servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts electrical energy from an inverter into synchronized mechanical motion for positioning tasks in industrial automation cells and conveyors. Its compact frame, feedback electronics, and sealed mechanical design allow it to fit inside multi-axis machines where precise speed control and quick dynamic response are required. It is intended for applications that demand fast response during repeated starts, stops, and speed changes.
At standstill the rotor can deliver a continuous torque of 4.4 Nm, so the axis can hold static loads without exceeding thermal limits. During operation the motor reaches a nominal speed of 3000 rpm. Accurate mechanical alignment is supported by the centering diameter of 95 mm, which mates with machined mounting surfaces to keep the shaft concentric. Position information is produced by an integrated multi-turn absolute encoder. That signal is transmitted through digital servo feedback, allowing closed-loop operation from power-up without a homing cycle and supporting stable position tracking across multiple shaft revolutions.
The motor uses a standard housing cast to dissipate heat and protect the windings. Its rotor is balanced to the DIN standard grade, which helps limit residual vibration during operation. Power and feedback conductors exit through a connector on the right side, which can simplify routing when the motor is mounted beside adjacent machine structures. Size code 071 and length code B indicate the magnetic stack used in this frame. The rear side is closed because the motor does not have a secondary shaft end. The drive end uses a plain shaft with a shaft seal, and the motor is supplied without a blocking brake.
