2 Drive definition Selection of wide variety of three-phase AC motors can be run on the CDA3000 motor inverter system. Three-phase AC motors are manufactured in syn- chronous and asynchronous design versions. The stator winding is desi- gned such that, when in service in a three-phase AC system, a rotating field is created in the motor which drives the rotor.
