Now take my writing up as something that defiantly needs clarification, hopefully from the folks
above. !!!!!!!
Edit : Clearly I have the wrong idea on why a motor has dual voltage capability
Its a three phase motor Matthew, not a single phase one.
The absence of the capacitor will be evident on a 3 phase motor, even if it didn't have a readable nameplate, you could be sure it was a three phase motor by this.
There's no point in trying to make it work on single phase
when you have a three phase supply, with 3 phase motor and switchgear already installed....
If the saw were going to a small home shop hobby style without any other machines
then it would be a VFD as it would be the cheapest/most suitable way to get a three phase
machine running from household supply.
(not compliant with health and safety)
While your taking pictures, make sure the machine is isolated (plugged out)
I suggest you have a look at the motor terminal box , 4 screws to remove cover.
I suspect that the configuration of the terminals is orientated to Star 380 volts or thereabouts,
and the 3 phase supply in the shared workshop is on 240 volts delta.
(just a totally uneducated guess, as I know absolutely nothing beyond VFD's for simple machines)
I have read that if you have a 3 phase motor orientated to star, but you only have
3 phase supply that is delta configuration, then loss of torque is a result.
It is the case if you were running a VFD/inverter like I do in my hobby shop.
If this is the issue, then other folks will be able to clarify if I could be onto something.
To check which orientation the motor is configured can be done at a glance, whilst the machine is isolated,
and takes about a minute to switch from star to delta configuration.
Take a look at Bob's Induction motor PDF
It has clear diagrams on star and delta configuration.
He is an admin on thewoodhaven 2
goes by the handle 9fingers, and the induction motor PDF
is underneath his signature.
(I cant get the PDF to link)
Hope this clears things up a bit for the knowledgable folks to give a more detailed reply on
anything important.
