    Ginormous outrunner.... in my washer!

    From a structural perspective, I would expect that increasing the power output from that motor would shorten the life of those ironless (?) cores - that plastic looks like it would creep and fail under much more than the load it was designed to have (turning a washing machine drum). I guess you...

    Question regarding AC Induction motor rotors

    Thanks for the reply. I can't see anywhere stating that the calculation presented in the quote is for induction motors, is this applicable to both PM and induction setups? Chris edit: If I could further clarify my question, coming from another angle; What would be the effect on efficiency...

    Question regarding AC Induction motor rotors

    Hi all. What is the significance of the number of induction bars on the rotor of an ACIM? Is there a general rule of thumb as there is with other PM motors? Do more bars reduce cogging? Are the limitations more down to manufacturability reasons? It seems to me that with a slipping field...

    DIY Sensored BLDC ESC - Assembly Thread

    Excellent project! Could this turn into the EV world's Megasquirt equivalent? Sorry if I missed it, but what are the ratings of this controller? Would it be capable of performing regenerative braking? Chris

    Lol I guess I should refresh the page before I post.

    Dual rotor axial flux motor design

    Surely if you spun the windings 180 degrees around the laminations, you would not be adding any turns while having the connections on the outside of the motor...? Or am I missing something? Chris
