Ceiling Fan Speed Controller Circuit

Note the crude circuit diagram on the black box object the fan speed controller i infer that the fan controller works by inserting a capacitance into the fan s power supply circuit.

Ceiling fan speed controller circuit.

The slow speed is obtained by using the 4 3uf capacitor purple p the medium speed is obtained by using the 2 1uf capacitor red r and the high speed is. Variable speed controls must be specially designed for use with ceiling fans. Wiring the fan to a variable speed control switch lets you make fine adjustments to the fan s speed. In the above ceiling fan speed control wiring diagram i shown the main winding running winding and i connect run wire of motor to the speed control switch and you can see it in above diagram that connection of run wire of motor in switch l point and and 1 and 2 for capacitor.

This wiring diagram illustrates the connections for a ceiling fan and light with two switches a speed controller for the fan and a dimmer for the lights. There are several ways to control ceiling fans and light kits. One wire switch to turn power on off to the fan and lights at the same time two wire switches one switch turns power on off to the fan the other to the lights pull chains to adjust fan speed and lights remote control available on new or existing fans to adjust fan speed and lights. A ceiling fan s wiring is integral when it comes to controlling its speed.

The source is at the switches and the input of each is spliced to the black source wire with a wire nut. In order to control the fan s speed the fan needs its own system of wires separate from that of the lighting element.
