I picked up a used 3 phase Shing Sheng 25” WDM-25 wide belt sander several weeks ago. I thought that the new shop I was about to move into had 3 phase power, but just found out it does not. The motor on this sander is a 10HP 3-phase 1750rpm with a metric frame. I am exploring options on what would be the most economical way of getting it going.

The way the motor is mounted, I could mount a replacement motor that does not have a metric frame. Lots of room around the motor and it is basically just bolted down in the bottom of the cabinet with room in every direction.

I know that my options are an RPC, or a new single phase motor. I have priced RPC’s and they seem to start around $1,200 and go up from there. I contacted the parent company of Shing Sheng and they said that they could send me a single phase 10HP direct replacement motor that would bolt right up for $750 but they are located in Taiwan and their shipping quote was $850! I found an electric motor shop that quoted me $900 on a new single phase 10HP motor but it would need some modifications to mount it inside the cabinet and I would need to have a pully custom made.

Do you guys have any other economical ideas that are below $900?

10HP single phase 1750 rpm with a metric frame. Copy that and google box it, ~$700

It looks like you are into some very serious machinery and it is likely that there will be more three phase motors in you r future. Is it possible to have three phase power run to the new shop at a reasonable cost?

No, I checked and the cost was more than I am willing to invest. I do have a large shop and many machines. But only one of them is 3 phase and I don’t see myself adding any more 3 phase equipment or any other equipment period. My shop already has 30+ machinery.

A wide belt sander is way more than just a motor when it comes to the power usage.
There are many switches and sensors that are also fed from the power source so even if you change the motor, there’s no guarantee that the machine will even start up.

There are air pressure sensors that will not even let the machine start if there’s no air pressure and if the power for that comes from the leg that’s not connected to the wall, you’re not going to have a functioning machine.

The control circuit can be fixed.

If you don’t plan to go the RPC route just get in touch with Jack Forsberg, he is active on many of the forums under his own name, and buy a VFD to run it. He is the man for quality/price and in particular 1ph in 3ph out VFDs for higher horsepower machines.

I sold a three phase wall fan to a single phase customer, and we had to source one of these drives. It worked like a champ!

Like woody said. A VFD is good for one motor. Controls would have to be rewired as well.

- TheFridge

To use the VFD you will need to wire around the starter and any e-stops in place, but if you stick with 60hz any other secondary electrics should work fine. Any e-stops can be wired into the low voltage accessory circuit of the VFD so they will work as before. The economics all depends on whether the OP does indeed not acquire any more 3ph machines or possibly lucks into a used motor/starter that will work.

Do they make VFD’s for 10HP motors that don’t cost thousands of dollars? I looked into an RPC but it was $1,600. I could get a factory new motor intended for my specific machine for under $1,500.

Yes, that is why I said to reach out to Jack. High output 1ph in 3ph out VFDs are a niche product and Jack has custom versions up to 25hp. Just look for him on SMC, OWWM etc.

Sorry, but that won’t work for the OP, that is a 3ph in 3ph out drive. The OP needs a 1ph in 3ph out drive which like I said is a niche product when you need over 5hp.

I don’t have Jack’s email, I always talk to him via PM and via forum but he is registered under his name at SMC and OWWM.

Tried registering on SawMillCreek but it kept saying my user name was already taken or did not work (I tried dozens). Anyone have this man’s contact info??
