Product Description:

The MDD093D-N-020-N2L-110GA0 is a three-phase AC servo unit built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is supplied as a motor for digital drive controllers, so its primary function is to convert precisely modulated stator currents into controlled torque and speed for automated machinery. When integrated with a matching drive, the model supports closed-loop motion sequences on pick-and-place axes, packaging stations, and light machining spindles where repeatable rotational positioning affects product quality. This arrangement allows the motor to respond smoothly to changing command values during acceleration, deceleration, and steady-speed operation.

At its rated operating point, the rotor reaches 2000 rpm, a nominal speed chosen to match gearboxes or direct-drive couplings that favor moderate mechanical amplification. Continuous torque at standstill is 24.0 Nm, indicating the holding force available for vertical loads before motion begins. Radial alignment to adjacent mechanics is guided by a centering diameter of 110 mm, while position information is delivered through digital servo feedback that streams incremental and absolute data to the controller. That feedback path allows the controller to monitor rotor position and speed continuously during operation. The power and signal plugs exit on side A, and both use connectors for straightforward cable attachment. Internal balancing and the cast-iron housing are standard, and the D length code indicates the active stack depth.

For applications that require passive load retention, the motor is supplied without a blocking brake, so any stationary holding must be managed by the drive or an external clamp. The rotor uses a plain shaft with a factory-installed shaft seal to limit lubricant migration and help keep contaminants away from the bearing area. With a frame size of 093, the device sits in the mid-range of the series. The standard shaft end is suited to pulleys or bellows couplings, depending on the driven mechanism. This shaft style also supports direct coupling where keyed transmission is not required.
