Usually the run winding consists of larger wire than the start winding. Thus the X/R ratio is high and current is lagging voltage. The start winding is wound with smaller wire, thus it has a comparat
This is as I have measured. Once the motor is running, can the high-resistance winding be disconnected? None of the centrifugal blower that I've seen switch the high-resistance winding out when the
I have used series capacitors for speed control of blowers with good success. A capacitor is much less critical than a resistor. It seems to provide a more stable speed too. On the subject of fans pu
Thus could run Good question, Rich. I was going to say yes, but I didn't want to answer so quickly without taking a look at the type of motor that is often seen on blowers (with attached 1-4uf capaci
I have seen air-compressor motors with a centrifugal switch/start winding, but I have never seen a centrifugal blower motor with such a switch. Air-compressor motors appear to draw c. 5-times the ra
