Product Description:

The MDD093C-N-030-N2M-110PR0 is a synchronous servo motor in the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. Designed for digital drive controllers, it converts regulated three-phase current into precise rotary motion for automated axes. The size 093 frame with length code C provides a moderate continuous torque envelope, while standard rotor balancing and a standard housing allow installation without special vibration damping. A centering diameter machined at the front flange aligns the unit with gearboxes or machine plates, helping maintain positional accuracy in multi-axis assemblies. This arrangement suits positioning duties that require steady response from a compact motor package.

Its rated operating point reaches 3000 rpm, enabling direct coupling to ball screws or belt pulleys in many mid-speed positioning tasks. The centering pilot of 110 mm helps keep radial runout within prescribed limits when the motor is flange mounted. Power and feedback connectors face the right side, so cable ducts can be routed parallel to adjacent axes in tight cabinets. A single industrial connector carries the three-phase supply, which keeps the electrical interface straightforward. The rotor is delivered without a blocking brake, so holding torque during standstill must be provided by the drive or an external mechanical lock. A standard shaft end on side A only avoids overhung loading on the unused side B.

Signal integrity is handled through digital servo feedback that transmits high-resolution position data to the controller. This channel is generated by an integrated multi-turn absolute encoder, allowing the axis to recover its position after power cycles without homing moves. To protect internal bearings from grease washout and airborne moisture, the output shaft is furnished with a shaft seal. Torque is transmitted through a ground steel shaft that uses a keyway, giving secure positive drive to couplings or pulleys under repeated acceleration profiles. The sealing arrangement also helps protect the bearing area when the motor is installed near dust or light moisture exposure.
