Question about KitchenAid Artisan KSM7580

Maybe the American horses are not so strong.
500 watts are 0.6798........ PS cannot be shaken or screwed.
1.3 hp is 956.148375 watts, which is also a given.
If you want to change this, you have to replace the formula collections worldwide.
There is a way to explain the whole thing.
If the motor consumes 1.3 hp or 956 watts of electrical power but only delivers 500 watts at the dough hook and heats the kitchen with the rest, then it is more or less correct.

I think (don't know) that the motor has a rated power of 1000W (great when counteracted by appropriate resistance) but in normal operation, e.g. beating egg whites until stiff, 500 watts are drawn.

It's only a commercial way to promote the product : the difference is in which kind of power we are talking about.
Peak power is not the Average power.
As we do use 230V in alternative current, it means we do have + 230V / -230V 50x per second (frequency = 50Hz), so peak-to-peak, voltage is double relatively to average voltage... If I'm not wrong :)

This is due to the efficient conversion of the power: Because the motor works with direct drive and is located in the upper area of the food processor, it can efficiently convert the power of 500 watts into 1.3 hp.
