Table Fan Speed Control Resistor Value at JENENGE blog

Table Fan Speed Control Resistor Value. Controlling the speed of the fan can be as simple as regulating the input voltage to the fan to using more complicated digital microprocessor. Find the current draw of the fan and calculate the value of the resistors you need using ohms law e=ir, where e is the voltage desired, i. The minimum is probably 50 or 60 percent. When the speed of a fan is reduced, the power required to drive it is greatly reduced. At full speed with a 5.2ω fan, a 3.7ω resistor in series should, according to my naive assumptions, drop the overall current to 1.35a. Power is proportional to speed cubed. The resistor value needs to be in the range 16 to 35 ohms, with a power rating of 1 w. To estimate the required resistance, it is necessary to have the complete motor. Learn how a linear circuit measures temperature and controls the speed of a cooling fan by generating a variable supply voltage for. Use the lower end if you want the fan speed. That means reducing the speed to 2/3 of full speed reduces the. Resistance control is probably not suitable for providing 25% speed. So you would use a resistor dropping 6 volts at 70 ma, and the resistor power would be 420 milliwatts. So use a half watt.

The minimum is probably 50 or 60 percent. To estimate the required resistance, it is necessary to have the complete motor.
