how many guys would run electric motors if there was an inexpensive option. We have been kicking around the idea of producing a chainsaw mill that uses an electric motor for a slabbing machine.
I don't see why not, three phase would help, if you don't have three phase you can get a phase convertor. Big sawmills use electric, works for them.
I have pondered this myself. What I'm hung up on is how electric motor power compares to chainsaw power in a real world application. How big of an electric motor would be needed to pull a 60+" bar and hang with a 088/084/3120? I dunno....
one thing to remember guys is that you need less electric HP then you do gas HP that is why train engines are deisel generators running electric motors. No transmission, no clutch and so on. The idea is to build a 220 outfit and I think a 3 hp motor for small mills and a 5 HP motor for larger mills.
I had originaly thought about using a 3ph motor and runing it through a variable phase controler to control the speed. Prpblem there is that the the vpc eats up a bit of the hp output of the motor.
My latest idea is to use a dc motor. Dc motors are really torqey and are the motors of choice for cars. just run the gererator through an inverter and then use a controller similar to a golf cartto control the speed. The thing about a dc motor is they have great low rpm torqe. Ive been looking at golf cart moters but they are a bit pricey and I can't find any info for how much they weigh.
