Abstract

PURPOSE: To automate zero power operation by a method wherein a position signal is cut off by the NOR outputs of a position detecting signal and a rotation detecting signal.
CONSTITUTION: When the output signals of a velocity detector 1 and a position detector 2 are introduced into a logical circuit 7 and the NOR is taken, the output of the logical circuit 7 becomes 'H'. A switch driving circuit 8 is constituted so as to cut a switch circuit 9 when the former receives the output signal 'H' of the logical circuit 7. Accordingly, when a roter has become stable in the state thereof, the logical circuit 7 detects it automatically and the zero power magnetic bearing may be realized.
