Product Description:

The MDD093A-N-020-N2L-110PB1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed as a motor for digital drive controllers, it converts regulated current from the drive into rotary motion for positioning, conveying, and indexing duties in factory automation lines. This design supports controlled axis movement in machinery that requires repeatable speed and position response during normal operation.

At standstill, the motor can deliver 9.2 Nm of continuous torque, giving actuators enough holding force for static loads without overheating. Its rotor is rated for a nominal mechanical speed of 2000 rpm, so motion profiles that demand moderate velocity can be executed without field weakening. Power and feedback conductors exit on side B through a sealed connector, simplifying cabinet layouts that bring cables in from the rear of a machine. Command accuracy is supported by digital servo feedback, which sends high-resolution position data to the drive for closed-loop control. A blocking brake integrated on the non-drive end supplies 11 Nm of holding torque to secure vertical axes during power loss. Mechanical vibration is controlled by ISO balance class Standard, which minimizes additional load on bearings during constant operation.

Mounting integration is helped by a centering pilot of 110 mm, allowing the frame to align precisely on gearbox or flange faces common to the 093 motor size. Length code A keeps the overall depth short, while the standard housing provides natural-convection cooling without fins. A shaft seal is installed at the output end, which helps limit dust and oil ingress so the keyed shaft can transmit torque to couplings without contamination. The shaft’s single-ended design leaves side B free for the preinstalled brake, and the keyed output simplifies torque transmission to pulleys or pinions in medium-inertia loads.
