Product Description:

The MDD090C-N-020-N2L-130PR1 is a three-phase synchronous servo motor manufactured by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. It is intended for use with digital drive controllers in automated handling, packaging, and material processing equipment. The unit provides repeatable rotary motion for axes that need controlled torque and stable speed regulation. Its synchronous design also supports accurate positioning during indexing and continuous-duty motion tasks.

At its rated operating point, the motor reaches a nominal speed of 2000 rpm, so the connected drive can maintain synchronous operation at a moderate axis speed. With the rotor at standstill, it can produce 10.4 Nm of continuous torque for holding force and low-speed feed applications. A built-in blocking brake adds 6.5 Nm of mechanical holding torque to secure vertical or suspended loads after power is removed. The motor uses a centering diameter of 130 mm for accurate alignment at the mounting face, and it has standard dynamic balancing to help reduce shaft vibration. Power and feedback conductors exit through a connector on the right side, which can simplify cable routing when the drive is installed on that side of the machine.

Position data is returned through Digital servo feedback (DSF), allowing the controller to regulate speed and rotor angle with high resolution. The primary shaft uses a keyway, and a shaft seal helps keep lubricant from entering the motor interior. The design does not use a second shaft end on side B, which follows the standard shaft arrangement for this model. The motor uses size code 090 and length code C, pairing the frame with the active core length used for its torque output. The housing is standard and provides the normal outer surface for convection cooling.
