Solid-state controls change the level of power in the fan motor to control the speed of the fan. For instance, when you switch from medium to high on a solid-state fan, the speed control mechanism increases the power of the motor.Click to see full answer. Moreover, how do you control the speed of a ceiling fan?When we switch on a fan, the voltage difference causes the current to pass through the motor and the fan rotates. The regulator controls the voltage that makes the current flow less or more. Lower the voltage lower the speed of the fan. So a regulator controls the voltage levels for the fan.Also, how does a variable speed fan switch work? In a capacitive type fan regulator, various combinations of capacitors is used to control the speed of the fan. (or voltage across capacitor is inversely proportional to the capacitance). Hence, if capacitance is increased then the voltage across the capacitor decreases allowing more voltage across the fan motor. Secondly, how does 3 speed fan switch work? With 3-speed motor, Hot voltage connects to main winding at 3 different points. Only 1 point at a time receives power. That’s what the fan switch does. When voltage is applied to each point, the main winding is energized as voltage from Black Hot wire completes circuit with White neutral wire.Does changing capacitor increase fan speed?You can change the capacitor and restore the rated speed of fan. However, that will not make it go any faster than its rated speed. The only case it might make the fan faster is if the capacitor used were smaller than ideal to begin with.
