Hi Bob
I have a motor query if you could assit!! Its for a drum sander build I am doing.
My motor doesnt give a hp or watt output on the rating plate.
As I understand it hp = volates (240) x Amps (3) x efficiency (???????)
How on earth do I find out the efficiency?
Currently that works out to be a 1hp motor ish (720 watts) but presumes 100% efficiency.
BTW I couldnt load your motor document or I would have read that first too.
