DTC P0A90-251 Drive Motor "A" Performance: Description

When three-phase alternating current flows through the three-phase windings of the stator coil, a rotating magnetic field is generated in the Motor. The system controls the rotating magnetic field in accordance with the rotating position and speed of the rotor. As a result, the permanent magnets provided on the rotor are pulled in the rotating direction, which generates torque. The generated torque is practically proportionate to the amount of current and the system controls Motor speed by regulating the frequency of the alternating current. Furthermore, the system properly controls the rotating magnetic field and the angle of the rotor magnets in order to generate high torque in an efficient manner, even at high speeds.
