Product Description:

The MDD093C-N-020-N2L-130GB1 synchronous motor is produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for digital drive controllers, it converts drive output current into controlled torque for positioning tables, gantry axes, and similar automation tasks. The unit uses size code 093, a standard housing, and a connector-based power and feedback interface for straightforward cable routing. Its synchronous design supports accurate speed regulation and repeatable positioning in machines that require stable motion over changing load conditions.

In operation, the rotor is balanced to Standard grade, which helps limit vibration transferred to the driven mechanism. The centering flange is machined to 130 mm, providing an accurate reference diameter for mounting to gearboxes or adapter plates. All electrical and feedback conductors exit on side B, where a keyed connector carries both power and signals in a compact arrangement. Position and velocity are returned through Digital servo feedback (DSF), allowing the connected drive to maintain closed-loop control during acceleration, steady running, and stopping. Under rated load, the motor reaches 2000 rpm, making it suitable for medium-inertia axes that need continuous torque without unusually high gearbox ratios.

For holding functions, an integrated blocking brake provides 11 Nm of static torque to secure the shaft when the drive is disabled. The mechanical output uses a plain shaft for direct coupling installation, and it is supplied with a shaft seal to help prevent lubricant migration into the motor interior. There is no second shaft end on side B, which leaves more installation space at the rear of the motor. The C length code indicates a longer active motor length, adding thermal mass and supporting continuous-duty operation without changing the outer diameter. That layout is useful in compact machine designs where torque capacity and mounting space both matter.
