<P>PROBLEM TO BE SOLVED: To increase a use efficiency and an operational availability of a motor by further improving a special motor disclosed in a patent document 1. <P>SOLUTION: A control unit 19 detects at least one out of lock stop, excess and deficiency of a rotational speed, and inverse rotation. A counter 41 of the control unit 19 counts the number of detection times. A single-phase AC synchronous motor 1 makes control for resuming a starting operation when the counted number is not more than a prescribed plurality of times, and makes control for stopping the operation when the counted number exceeds a plurality of prescribed times. <P>COPYRIGHT: (C)2011,JPO&INPIT |
