摘要: A voltage application unit causes switching elements to apply flow an electric current into corresponding windings generate a revolving magnetic field. period derivation derives energization of the windings. signal generation generates PWM for causing activate and deactivate elements, such that duty ratio decreases gradually in predetermined time subsequent derived period. specifying specifies detection current, which is supplied from presently switched deactivated, by between edge, caused when changes level point advance edge
