Product Description:

The MDD093C-N-040-N2M-130GL0 synchronous servo motor is manufactured by Bosch Rexroth Indramat as a member of the MDD Synchronous Motors series. It serves as the electromechanical output stage for digital drive controllers, converting commanded currents into precise rotary motion for packaging lines, pick-and-place units, and machining centers. This model uses the C length variant of the 093 frame, carries standard rotor balancing, and is enclosed in a standard housing, providing consistent mechanical behavior and vibration limits for general industrial environments. Its operating role suits axes that require repeatable starts, stops, and short positioning moves under changing load conditions.

A centering flange diameter of 130 mm positions the stator accurately on mounting surfaces. The rotor can sustain a nominal speed of 4000 rpm, giving high peripheral velocities without oversaturation of the magnetic circuit. Frame code 093 sets the overall outer dimensions and matches the mechanical envelope used for this motor size. Power and signal cables terminate on a keyed connector mounted on the left side of the housing, and feedback returns to the drive through digital servo feedback for tight position and velocity control. The left-side connection layout can help when cable runs are routed along one machine wall, reducing interference with nearby guarding or tooling.

Motion is delivered through a plain shaft, and the absence of keyways minimizes stress concentrations in cyclic torque applications. A fitted shaft seal blocks lubricant egress and helps protect the interior from splash or dust. The motor ships without a blocking brake, so static load holding must be supplied by the drive or an external clamp. An integrated multiturn absolute encoder records rotor position across power interruptions, and the single-ended shaft arrangement on side A eliminates the need for a secondary shaft on side B, reducing overall length. The shaft layout also leaves the non-drive end less crowded, which can simplify placement near couplings, covers, or other adjacent machine components.
