摘要 |
A position detector generates a control signal by detecting terminal voltages at the input/output terminals through which the electric currents flow into three-phase coils. Filters convert terminal voltages into smoothed signals. A synthesizer produces three kinds of synthetic signals from the smoothed signals. A compurator produces control signals to switch the current path to the three-phase coils based upon signals formed by comparing the synthetic signals with the smoothed signals. The current path to the coils is switched in turn by a switch drive unit in response to control signals generated by the position detector.
