Thread: ML392 - Sherwood 10 inch Combo Thicknesser / Planer motor blown. Help Please!

Well, what can I say.... may have to be a bit gentler with it next time, once you hear the motor start slowing down, you have to back off the load and let it run free for a while.
Hares and Forbe should have an induction motor that suits. Your manual should give you the spec for the motor.

yes, lesson learnt the hard way there. Thanks for the reply!

I just called Hares and Forbes and they said that they can no longer get parts for that machine including the motor...

I just so happened to have the instruction manual in front of me next to my laptop,

There's no motor details but I am pretty certain these are 2HP - thats what the new ones are anyway.
There's no motor RPM but the cutter speed is 3750 rpm so all you need is the pulley ratio and we can work out the motor RPM - it will probably be 2850 rpm

The motor will be pretty generic so a Conon motor will probably be OK.

If you need a hand to swap pulleys, make new mount points, wiring etc , give us a hoy.

To start with pull the motor out and measure
- the shaft diameter
- the footplate hole spacing

If you drop the old motor around to me I can also really ascertain if its truly dead.

Just look up on the internet. ML392 is actually AW109PT2, and according to the manual is a 1.5KW motor. There is no other information on the manual, but I would guess it is a 2-pole motor 2880 rpm.
This is equivalent to Carbatec 10" combination planer.
You have 3 options:
1. try Carbatec to see if they have a motor.
2. choose a generic motor from Hare and Forbes after confirmation of the motor spec and try to fit it in there.
3. Get your motor rewound by someone local, like Home - Perth Rewinds Electric Motor Specialists

thanks justonething and BobL

Carbatec haven't stocked that model for a while but I have sent them all the specs and they are going to see if the current models motor is suitable.

a rewind is not the best option as it works out to be quite expensive ($400-550 based off quotes). Timbecon can get me a new motor for around $200-250... but there is around a 2 month + wait as it has to come from china and via sea container....

The shaft size on the motor is 20mm but if I get another motor I can always get a different pulley to suit, learning as I go so thanks for the advice!

Bob - thanks for the link, the footplate is quite different but im sure there are ways around that. I'm send you a PM.

thanks again!

There are indeed many workarounds possible. I just finished converting a couple of machines with odd footplate 3Phase motors to single phase where some of the footplate were quite different.

I just realised I showed a link to a 3P motor above - they also have the single phase equivalent as well.

Cossi,
If you are getting a generic motor, make sure you're getting a motor based with the right phase count. I could be wrong, but my suspicion is that your motor is on a single phase 240V 50Hz supply using a simple 10A socket. If that is the case, single-phase 240v 1.5kw/2HP 2800pm shaft 24mm Compressor motor electric motor | eBay would be more suitable.

Could try a motor from a second hand garden shredder these are pretty cheap second hand on gumtree and many are 2400 watts around 3 HP. I have one driving my jointer.

Thanks guys for your help! Carbatec finally got back to me and they have a replacement motor there for my model! )

BobL, - I have tried to message you a few times but something has always stopped it working and in my busy state I have had to leave it and try again later. All sorted now though.

Whilst chatting about replacement motors, have you had any experience with swapping out radial arm motors (3Phase).... this one was on my list as well but not as urgent as I have been finding ways to use my table saw. )

Do you mean SMS or PM ?- if SMS I have changed my number

I have never swapped one out as most of ones I have seen are usually integral to the saw body. I might be able to convert it to 240V 3phase so you could run it off a VFD?

As the others have pointed out, either of the single phase Ebay motors for a 10" planer will do you just fine. If the shaft on the new one is bigger you can just ream out the pulley. The only thing of concern will likely be the way the motor is mounted. Some are collar mounted, some via base flanges. But it's nowhere near as difficult as some may think.

I'd recommend avoiding anything 3PH so you don't have to worry about fitting start/run caps, and/or a VFD. The 3PH ones you find new on Ebay are ready to go with the correct value start/run caps and are thus listed as 240v.

cheers, Ian

Sorry Ian but this is not correct. 3 phase motors do not have start or run capacitors. They can only be run from a 3 phase supply whether that 3 phase comes from the grid or a VFD. 3 phase motors listed as 415/220V are capable of running on either 415V 3 phase from the grid or 220V 3 phase from a VFD.
