Product Description:

The MDD093C-N-040-N2L-110GA1 is a three-phase synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Engineered for digital drive controllers, it supplies closed-loop torque and speed in automated transfer lines, material-handling gantries, and general machine-tool axes. By pairing with compatible Indramat drive modules, it delivers rapid acceleration and stable running velocity so mechanical cycles remain synchronized with controller demands. Its synchronous design also supports accurate positioning during repeated start-stop motion and coordinated multi-axis movement. This makes the motor suitable for applications that require frequent reversals, short settling times, and repeatable velocity control under changing load conditions.

Its mechanical interface uses standard balancing, allowing direct coupling without extra counterweights. The centering pilot is 110 mm, which keeps the motor aligned within mounting flanges and helps reduce concentricity error at the machine interface. Power and feedback plugs are routed on Side A through a sealed connector interface, which keeps cable entry organized and protected. The motor has a frame size of 093, while length code C provides a longer active iron stack for higher torque density in this housing. The housing uses a standard laminated construction and does not rely on external fins for its basic form factor. During operation, the motor reaches a nominal speed of 4000 rpm, so the connected axis can support high-speed motion when the drive and mechanical load are matched appropriately.

An integrated blocking brake supplies a holding torque of 11 Nm, keeping vertical or suspended loads from drifting when the drive is disabled. Position feedback is handled by the internally mounted digital servo feedback transducer, which gives the controller the rotor data needed for commutation and closed-loop regulation. To limit lubricant escape and particle ingress, a shaft seal surrounds the output journal, and the motor uses a plain shaft for flexible coupling to hubs and pulleys. The shaft extends only on the drive side, with no side B extension, which helps keep the unsupported end compact and reduces extra overhung mass. This arrangement also leaves the non-drive end clear where rear shaft access is not required.
