Product Description:

The MDD093C-L-030-N2L-110GR2 is a synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Supplied for use with digital drive controllers, it acts as the electromechanical output device on coordinated motion axes by converting commanded stator current into precise rotary movement. The motor is suited for gantries, tooling spindles, and material-handling stages where repeatable speed and position tracking are required during continuous duty. Its synchronous design also supports stable closed-loop motion when the drive must regulate both speed and position over changing load conditions.

This model uses standard rotor balancing to keep vibration within IEC limits, and its centering diameter measures 110 mm for accurate alignment with matching machine housings. Power and feedback conductors exit on the right side through a sealed connector, which helps keep cable routing compact in confined installations. The aluminum housing is designed for surface cooling, so heat can be transferred to an external mounting surface or removed by directed airflow. A built-in blocking brake provides 22 Nm of holding torque to maintain position when power is removed. During operation, the magnetic circuit supports a nominal speed of 3000 rpm. The motor also has length code C, a standard single-ended shaft arrangement on side A, and an installed shaft seal.

Closed-loop control is handled by the integrated Digital servo feedback (DSF) unit, which returns high-resolution position data to the drive for fast current and velocity correction. The frame designation 093 places the stator and rotor in a medium-power size that balances torque capacity with installation space in multiaxis machinery. A plain shaft is supplied instead of a keyed or splined version, making the motor suitable for clamp-style or shrink-fit hubs. This shaft style can help reduce backlash from mechanical connections that rely on frictional clamping rather than positive key engagement.
