Inductance vs capacitor elec motor?

There is a big old GE inductance 220 1hp electric motor up in the corn crib. It went bad last nite. (I won't talk about the 3 days of snow coming this afternoon, getting the corn out, 2 acres of bean left & the combine broke too, and such....)

Can this thing be replaced with a modern capacitor motor? When the real old one went bad I was in high school, and I recall there was an issue of the whole farm having thin wiring, this being a very high start-up load, and that it should always be an iductance electric motor.

It runs a flat conveyer belt up in the peak of the crib to distribute the ear corn, and does take quite a drag to rev up to speed. After that the 1hp seems to run it fine. Would a capacitor motor be able to do the job? I could safely go to 1.5 hp I guess, would not want to push the thin wiring beyond that. (Used to be a 110 circut that ran the 1hp ind. motors, dad upgraded to 220, but used the same &^%$% thin wire on a long overhead run...)

As long as you read this far, wonder what went wrong with the old motor? It makes noise, spins slowly in either direction, has no power.

Thanks from a frustrated farmer during a very long fall,

Induction motors do take time to "spin up" to speed. They aren't fast starting like a universal motor.

Seeing as you are running it on 220v, your amperage load is really quite low, especially on a 1HP motor. 1HP on 110v is roughly 11-12 amps. 1 HP on 220v draws about 5-6 amps, but startup amperage draw can be around 12-15 amps.

Can you specify the gauge of wiring you are using? It might seem thin, but keep in mind, 220v motors draw about half the amperage of 110v motors of the same HP rating.

You might have the best luck using a TEFC motor (totally enclosed, fan cooled).

The old one might have been a repulsion start, induction run, motor. As far as I know, no longer available. They had the higest starting torque AND the lowest starting current inrush of all the single phase motors- so would have been good for the situation you described. Going with 1 1/2HP might not be the answer, since it draws even more current. Do look for a motor that has a high Service Factor (SF). That means that it functions at lower than standard voltages. Your long thin wire is causing much voltage drop. Get at least a 1.15 SF- a 1.25 is better and if possible to find a 1.5 SF, it would be the perfect choice. A 1.0 SF will not last long for your application.
