MDD071B-N-030-N2T-095PR1
The MDD071B-N-030-N2T-095PR1 is a brushless synchronous motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for direct connection to digital drive controllers, the unit converts drive current into controlled rotary motion for indexing tables, packaging stations, and light conveying axes in automated plants. This arrangement lets the drive regulate speed and position with repeatable response during cyclic motion. Its B length code and 071 frame size give a balanced ratio between footprint and torque, while the standard housing, standard rotor balancing, and a single shaft end simplify mechanical integration.
Mechanical centering to the mounting flange is secured by a 95 mm pilot, which helps keep radial runout low during high-speed operation. The motor supplies 4.4 Nm of continuous torque at standstill, which is suitable for holding or slowly moving process loads without overheating. Rated speed reaches 3000 rpm, matching the operating range of common PWM amplifiers so dynamic cycles can remain short. Position and velocity data are returned through digital servo feedback, allowing the controller to make closed-loop corrections in real time. Power and feedback conductors exit through a right-side connector, which keeps cable routing compact and reduces bend stress at the outlet.
A blocking brake integrated on the non-drive end produces 3.0 Nm of static holding torque, which helps prevent axis drift when power is removed. Motion feedback is supported by a built-in multi-turn absolute encoder, so stored revolution data remains available after shutdown. The output shaft carries a shaft seal that limits dust and coolant ingress, and its keyway profile provides a positive drive interface for pulleys or couplings. This combination is useful on compact axes that must remain in position at rest and return to controlled motion with retained position information.
