<P>PROBLEM TO BE SOLVED: To provide a three-phase induction motor by a digital three-phase AC generator whose circuits are bidirectional, that is applicable to high frequencies, that has large torque at a low frequency, that minimizes current consumption, and that can obtain large torque even at low voltages like 3V. <P>SOLUTION: In this three-phase induction motor 13, an input A=(111000), an input B=(001110), and an input C=(100011) are provided, and a negative input AA=(000111), a negative input BB=(110001), and a negative input CC=(011100) corresponding to each input are provided. Actions inside the parentheses are each synchronized in the sequence from the left. Also, a drive circuit of the motor 13 repeats the synchronized actions inside the parentheses. <P>COPYRIGHT: (C)2004,JPO |
