Abstract
The utility model relates to a single-phase brushless DC permanent magnet motor controller, which comprises a voltage switchover device, which comprises a command switch, a control circuit, a drive circuit and an inverting circuit. The command switch consists of a Hall IC, the control circuit consists of a LM integrated chip, the drive circuit consists of a LM integrated chip, and the inverting circuit consists of a field effect tube. The utility model is characterized in that the operating frequency of the LM integrated chip of the drive circuit is above 10M, and the inverting circuit has at least one field effect tube. Because the single-phase brushless DC permanent magnet motor controller of the utility model is not required to rectify, the rectifying circuit is omitted, and the number of the field effect tubes is decreased. Thus the utility model is characterized in that the cost is low, and the stability is good.
