Product Description:

The MDD093C-N-020-N2M-110PB0 synchronous motor is built by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it provides commanded motion to positioning tables, gantries, and packaging stations where rapid direction changes and consistent torque are required. In closed-loop motion systems, it works with a compatible drive to convert electrical commands into controlled rotary movement for repeatable axis operation. The housing follows the standard build, so the mounting dimensions remain consistent with other motors in the series.

Mechanical alignment is aided by a centering diameter of 110 mm, and the rotor is trimmed to standard balancing quality to reduce vibration during high-cycle operation. All electrical and feedback plugs face side B, and the power leads terminate in a keyed connector that matches Rexroth drive cables. The unit uses length code C with frame size 093 to indicate the active stack height, while its nominal speed reaches 2000 rpm for medium-speed axes. Position data comes from an integrated multi-turn absolute encoder, which sends angle information to the controller without requiring a homing routine after startup. A single-ended output shaft with a keyway transfers torque to couplings or pulleys, and the opposite face is left blank because the motor does not have a side B shaft extension.

Closed-loop current control is supported through digital servo feedback (DSF), allowing the drive to correct load disturbances during operation. The motor is supplied without a blocking brake, so stopping and holding functions must be handled by drive torque or an external clamping device. A shaft seal sits behind the front bearing to help protect internal laminations from coolant mist and fine dust. This arrangement supports use in areas where moisture or airborne particles are present around the machine axis.
