How to slow down a fan motor
WebA Variac will give you the best consistent results controlling fan speeds for all fan types, but they are large and heavy, cost about $50 used. The next best thing is a fan dimmer, or speed control meant for use with fans and has a minimum speed adjustment. WebLeading to a smaller Hysteresis loop, increasing motor efficiency by reducing iron eddy current losses. I have a Carrier furnace/heat pump with an expensive control thermostat that talks directly to the heat pump. It allows three constant fan speeds as well as an automatic fan speed and a variable burn rate and compressor and fan speed.

WebJul 1, 2011 · This will reduce the voltage across the fan. Since the overall circuit resistance will increase (Fan + Resistor) the overall circuit current will decrease. If the fan specifications are known a resistor can be chosen to reduce the voltage across the fan as a result of reducing overall circuit current. Current limiting. Web1. The fan most likely has an asynchronous AC motor and this means the speed of the arrangement is bound to be near the synchronous speed (of 3000rpm at 50Hz). You …
WebYou can add a resistor, a capacitor or an inductor in series with fan permanently. This will increase overall impedance and reduce the current, thus reducing the fan speed. Another possibility is to change the capacitor in auxiliary winding from 2.25 mfd to say 1.85 or 2 mfd. This will reduce fan speed. Lawrence C.
WebOct 2, 2011 · As I understand it, given that it is a brushless AC motor, the only way to slow it down to a calculated speed is to rapidly turn it off/on with use of a 555 IC.
