    A formula for eddy current losses in copper conductors?

    I've been toying with the concept of liquid cooled conductors in a coreless PM motor, in the shape of 2x3mm copper tubing. From a thermal point of view, it seems like a 30mm length water cooled length of that tubing (my example length) can sink about 7W of power, putting power density at over...

    motor design, please help looking over numbers

    So, I'm checking the design of a motor for an EV, as a sort of feasibility study while I decide what to do with my broken car. Some numbers don't seem to add up, so if anybody spots any mistakes, I'd be very thankful. I'm an EE, but I've not had to compute this stuff for an electric motor since...
