1. Fan Regulator
A fan regulator, also known as a fan speed controller, is
an electronic device used to control the speed of an
electric fan. The basic concept behind a fan regulator is
to control the voltage and/or current supplied to the fan
motor, which in turn controls the speed of the fan.
2. The most common way to achieve this is through the
use of a rheostat, a type of variable resistor that can be
adjusted to control the amount of electrical current flowing
through the circuit. This can be done manually, by
adjusting a knob or switch on the regulator, or
automatically, through the use of a thermostat or other
sensor that can detect changes in temperature or humidity.
3. Another way to achieve this is through the use of a
Pulse Width Modulation (PWM) signal, which can be used to
rapidly switch the voltage on and off to the fan motor. This
creates the effect of varying the voltage, and thus the speed
of the fan.
In summary, the engineering concept behind the fan
regulator is to control the voltage and/or current supplied to
the fan motor, which in turn controls the speed of the fan.
This can be done through the use of a rheostat, a type of
variable resistor or through the use of a Pulse Width
Modulation (PWM) signal.
