Abstract
The utility model discloses a permanent magnetism alternating current synchronization motor system used for a blower fan coil pipe. The permanent magnetism alternating current synchronization motor system used for the blower fan coil pipe employs a permanent magnetism alternating current synchronization motor and an intelligentized driver. A multi-shift power supply of a wind speed regulator is sent to a power supply interface of the driver. The power supply interface outputs a 220V alternating current to a filter circuit after identification processing, and the 220V alternating current is further sent to a rectification module. At the same time, the power supply interface also outputs multi-paths of speed shift signals to a control module. A high voltage direct current and a low voltage direct current is output, after the 220V alternating current is subjected to a filtering process and a rectification process. The low voltage direct current is used as a working power supply of the driver. The high voltage direct current is connected to an inversion circuit. The inversion circuit converts the high voltage direct current into a three-phase alternating current sine wave current used for driving the motor to operate. A remote communication interface receives remote control signals, and is connected to the control module. The speed switch signals and the speed switch signals are subjected to the processing carried out by the control module, and then control signals are output to the inversion circuit. The voltage and the frequency of the three-phase alternating current output by the inversion circuit are adjusted to control the rotating speed of the synchronization motor. The beneficial effects of the permanent magnetism alternating current synchronization motor system used for the blower fan coil pipe of the utility model are that: the synchronization motor is advantaged that the synchronization motor is high in efficiency, low in noise degree, reliable in operation, simple in structure, and low in manufacturing cost; the intelligentized driver has a multi-shift power supply identification function and the remote communication interface, so that the system is compatible to the current general blower fan coil pipe; and remote control is provided with a technical support.
