The 90-550W heat pump ac fan motor manufacturer tells you that the internal structure of an AC fan (single-phase) consists of two coil groups, one of which is a winding and the other is a running winding. These two windings are connected in series to form a Three points, the series point is the common end, the 90-550W heat pump ac fan motor manufacturer tells you that the start winding end is the start end. The running winding end is the running end. The AC fan also needs a start capacitor, usually the capacity is between 1-2uf. , The withstand voltage is usually 250v, which refers to the normal use of the mains AC motor.

The 90-550W heat pump ac fan motor manufacturer tells you that this type of capacitor is a polyester capacitor. There are no positive and negative poles. There are two connectors. One end is connected to the end of the starting winding and the other end is connected to the end of the running winding, forming a triangular shape, 90- The manufacturer of 550W heat pump ac fan motor tells you that the power supply (there is no need to distinguish the live line and the neutral line) one is connected to the end of the running winding (that is, it is also connected to one end of the capacitor), and the other is connected to the common end, and the grounding wire is connected to the motor housing.
The manufacturer of 90-550W heat pump ac fan motor tells you that usually the start winding of a single-phase AC motor can also be used as the running winding. At the start end, the 90-550W heat pump ac fan motor manufacturer tells you that this is to use the start winding as the running winding), and the motor will reverse. This is the only way to change the direction of the single-phase AC motor!
