Traded for a MIKIWAY MBS-250

[Dick Brown]

Fellow had this saw on Craigslist and we ended up in a trade. It is a 5 hp. 3 ph. beast that weighs something over 400 lb. Problem is I don't have 3 ph. power.
I know her are options but having never had to deal with it before, really never paid much attention. What are your thoughts on best way to go, performance, cost, etc ? More than likely will not keep the saw but would be good to have the info to pass on to a new owner. Here is link to a picture. http://mikiway.com.tw/www/p1.htm

I would think that you could source a VFD to run the tool on single phase power with reasonable retention of power.

I installed a static converter for my milling machine and engine lathe long before VFD’s came into vogue. IIRC it was around $100. It’s not the best option but its been doing the job for ~ 25 years. The best option is a rotary converter. ($$)

Converted my TS to variable speed. Never going back! VFD is the way to go.

[Matt Day]

You’re options are Rotart Phase Converter, Variable Frequency Drive, or Static Phase Converter. I’d vote VFD as there’s no derating of Hp like a SPC. If the buyer or you don’t need 5hp, get a 3hp and it’ll run you $200 tops. Getting a vfd for 5hp can get expensive.

[Mike Heidrick]

Huanyang 5hp vfds are cheap.

Heck a 10hp sigle phase in rated vfd (no derration) will only run you $255.
