Single-phase permanent magnet synchronous motor is driven after deceleration.  Air conditioning fan (cold fan) motor This fan blows the air at a lower temperature than ordinary fans.  Its principle is that the single-phase hood pole asynchronous motor or single-phase permanent magnet synchronous motor drives the water (or ice water) curtain to move slowly and roll up and down, and the single-phase capacitor operation motor drives the fan to blow out the air with constant humidity around the water curtain, which makes people comfortable in hot days.  The drier the climate, the more significant the effect of hot blowing out cold wind, because there is a certain humidity, and the effect of purifying air E gas.  The electric heater is also called the hot air heater. When working, the cold air inside the room is sucked in behind the fan and heated by the electric heating element and blown out, so as to achieve the purpose of heating.  Most fan motors use single-phase hood pole yi step motor, the general rated power is 25-40W.  Some heaters are installed at the bottom of the single-phase permanent magnet synchronous motor with a reducer, so that the device is around the reciprocating rotation (return Angle 80 degree a 90), suitable for many people or a large range of heating.  (2) Microwave oven household microwave oven is a kitchen appliance that uses electromagnetic waves of 2450MHz frequency to heat food.  The working principle of microwave oven is that when the electrons emitted from the cathode of the magnetron move towards the anode, they are affected by the axial magnetic field produced by the permanent magnet in the magnetron. In this way, the electrons make cycloidal motion under the dual action of electric field force and magnetic field force, and oscillate in the resonant cavity to generate 2450MHz microwave, which is input into the furnace cavity through the waveguide to heat food.
