Product Description:

The MDD093A-N-040-N2L-110GB0 synchronous servo motor is manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it converts drive output current into rotational motion for positioning and velocity control in automated machinery. Operational data is returned to the controller by digital servo feedback, allowing closed-loop regulation of position and velocity with high resolution. This feedback arrangement lets the matched controller correct motion deviations during acceleration, deceleration, and steady operation. It is suited to automated axes that require controlled rotary motion rather than simple open-loop operation.

The unit delivers a continuous standstill torque of 9.2 Nm, so the axis can hold static loads without overheating while the drive remains energized. Under rated excitation, its rotor reaches a nominal speed of 4000 rpm, which fits high-cycle pick-and-place or spindle tasks that require fast transitions. Mechanical alignment during installation is assisted by a centering diameter of 110 mm on the flange, and the rotor uses standard balancing to limit vibration at high speed. Power and feedback conductors exit on Side B through a sealed connector, which keeps cable routing on one face of the machine. The motor uses size code 093 and the short A length code, so it takes up less depth than longer motors with the same flange pattern. Its housing dissipates heat by natural convection, which keeps the motor layout simple and avoids the need for separate motor-mounted cooling hardware.

For applications that depend on drive torque or external mechanics to secure the load, the motor is supplied without a blocking brake, eliminating residual drag when power is removed. The rotor interface is a plain shaft on side A only, so there is no shaft extension on the opposite face and the coupling layout stays simpler in compact machines. A factory-installed shaft seal protects the interior against airborne dust and low-pressure water jets so the assembly maintains IP65 integrity. This sealed shaft area also helps protect internal components in environments where light splash or contamination may be present.
