Quick background. Most motors use a "start capacitor" to get the motor spinning. This (capacitor) is disabled by a centrifugal switch once it is up to speed. The problem is, a discharged capacitor "looks like" a dead short and will trip out most inverters. The "trick" is to charge the start capacitor "slowly" (instead of a few msecs, to hundreds of msecs).
The Micro-Air EasyStart does this ! It was designed for A/C, but there is no reason it should not work for ANY motor that has a start capacitor. Not cheap !
I know my mill has a start capacitor, but I always thought that it was to ensure the motor started, rather than getting....probably getting the names wrong.....but where the stator is between two windings, so instead of rotating, it is sort of frozen in space. I know I've had to replace one in one of my motors for something, I want to think it hummed, though. Have to admit, my knowledge of electrical systems is above the average Joe, but likely less than a lot of folks here.
I've seen some less expensive ones. Hoping I can get by with one of those. I've been wondering if those were some sort of capacitor, to be honest. It kind of seems like it may help provide a buffer? However, soft start systems are generally required for most inverters, so that doesn't seem to make sense. Now all that said, the inverters I"ll be using are pretty big, and supposedly very robust. Sol-Ark 18K if that means anyhting to yoyu.
