Product Description:

Bosch Rexroth Indramat manufactures the MDD093A-N-030-N2L-110PB2, a motor for digital drive controllers in the MDD Synchronous Motors series. Installed on numerically controlled axes, it converts regulated current from the inverter into precise rotary motion that follows the commanded position profile. The unit couples readily to gearboxes or belt transmissions and is deployed wherever closed-loop positioning, repeatable torque delivery, and compact mechanical envelopes are required on assembly lines, palletizers, or packaging machines. Because it is intended for coordinated axis motion, the motor supports accurate tracking during indexing, interpolation, and other repetitive machine movements.

The rotor can reach a nominal speed of 3000 rpm, matching the drive’s programmed output frequency. During sustained holding periods, it delivers 9.2 Nm of continuous standstill torque, which helps prevent load drift without overheating. If power is removed, an integrated blocking brake supplies 22 Nm of static torque to keep the shaft locked. Accurate alignment with the driven machine is aided by a centering flange of 110 mm. The 093 frame indicates the outer diameter class and matches couplings of similar load capacity. Standard dynamic balancing limits residual vibration, and the closed aluminum housing uses convection cooling while motor length code A indicates the shortest active stack available in this frame to reduce installation depth.

Power and feedback conductors exit toward Side B, which can simplify cable tray routing in inline gantry layouts. A circular industrial connector serves as the single electrical interface and keeps the connection compact in confined machine spaces. Rotor position is returned to the controller through digital servo feedback, enabling high-resolution speed and position loops. This feedback arrangement lets the controller monitor rotor angle continuously and correct speed deviations quickly during acceleration and settling. A shaft seal at the output end blocks coolant spray and dust from the bearing cavity. Torque is transmitted by a keyway in the solid shaft, while the opposite side remains unused because the shaft end is supplied only on the drive side.
