Single-phase motors need to generate a torque (a rotational force) in order to spin. Then this torque is obtained by combining the coil with the capacitor (starting winding) and the coil without the capacitor (main winding).
If the exhaust fan doesn't turn, it's because the capacitor is broken, and the fan makes a loud sound, but it just doesn't turn. If you turn the fan with your hand, the fan rotation is normal. That's what this capacitor does: to generate a starting torque.
The opening or closing of the kitchen exhaust fan will affect the TV in the living room and the kitchen next to the living room, the exhaust fan power supply and the living room TV power supply are just on the front and back of the wall, these 2 points can be guessed that the electricity in the kitchen and the electricity in the living room are from the same line, and the impact is because the size of the wire is too large, and the current should be evenly distributed to the TV and kitchen appliances. (If you turn off the TV, the kitchen lights will be much brighter), and the same goes for the bedroom. The load is large and the wires are small. >>>More
First of all, don't listen to superstitions, any feng shui is also a lie. >>>More
Do you have any experience in repairing electrical appliances? First of all, check whether the coil has been burned out, then there is no need to repair it. Second, if the coil is good, see if the shaft is stuck. Third, capacitance.
The power is related to the model and specification of the exhaust fan, the general household from more than ten watts to forty watts, the noise mainly depends on the quality of the motor, and the good exhaust fan motor is imported from Japan. Generally, no more than 1 kilowatt-hour of electricity is turned on a day.
Exhaust fans are usually installed in the bathrooms at home to help us better ventilate. Do you need an exhaust fan in your kitchen? Next, PChouse will talk to you. >>>More
