Product Description:

The MDD090C-N-040-N2M-130PA1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is supplied as a motor for digital drive controllers, so it converts commanded current from the drive into precise shaft rotation for positioning and transport tasks in automated machinery. By combining the motor, feedback system, and brake in one housing, the unit supports compact axis layouts for packaging machines, gantry slides, and material-handling stations. Its synchronous design also supports repeatable starts, stops, and reversals where accurate motion is required.

Within its mechanical envelope, the motor reaches a nominal speed of 4000 rpm, giving it a moderate base speed for pick-and-place or spindle duties. At standstill, it can deliver 10.4 Nm of continuous torque, allowing sustained load holding without overheating. The centering shoulder measures 130 mm, matching the flange dimensions used on the 090 frame for accurate alignment with gearboxes or machine plates. Cabling exits on side A through a sealed connector, keeping encoder and power conductors away from moving parts. The motor size code is 090, and its C-length stator increases active copper without enlarging the footprint. This helps maintain torque density while keeping the motor suitable for compact machine layouts.

Position information is generated by an integrated multiturn absolute encoder, while the drive uses digital servo feedback to close the velocity and position loops. This arrangement lets the control system retain position information across multiple revolutions after power cycling. A blocking brake supplies 6.5 Nm of holding torque so vertical axes remain fixed when power is off. The shaft is machined with a keyway for positive coupling to pulleys or couplings, and a shaft seal is fitted to help prevent oil ingress into the front bearing region. Standard dynamic balancing and a sealed housing help reduce vibration and limit contamination during long-term use in automated production lines.
