Hard start capacitor
I have this posted on another forum and don't seem to be getting any answers to the question. Okay guys, my knowledge of electricity does not even make me dangerous. I have been doing a lot of read...

Not so sure the micro air uses that old school method of starting motors. Have to deal with the heat from the resistors and the unit comes in a sealed plastic housing. I've serviced a few industrial motors and those reduced voltage starters using resistors you described get replaced with either soft starters or if speed control is desired VFDs.
Bottom line is you have to limit that huge start current spike. The cheapest way is a resistor. As for heat. The resistor is only "in the circuit" for less than a couple of seconds.
Industrial motors to me implies 3 phase. That is a whole different kettle of fish but a variable frequency device (VFD) work very well.
