Electric Motor

[bill barlow]

I have a 750w electric motor. When it is drawing 1100w am I right in thinking the power output is still only 750w??

I'm unsure how motors are rated but if it is by power output then by definition it would still be 750w output (and 350w of heat !)

I've tended to assume the power rating was for what it drew though, otherwise working out the fuse needed will be a rough estimation, but I may have been always wrong about that.

Are you saying it's a 750W motor because that's what it says on the rating plate? Like OG, I've always taken that to be the product of the voltage and the current, and I'd be somewhat concerned if it was drawing 1100W.
Assuming you're in the UK, does it say 230V or 240V or thereabouts?

[bill barlow]

It is taking a constant 230v

Are sure that you are not comparing Watts with Volt Amps?

Interesting thought. A motor is rather inductive.
