    Mosfet SWAP?

    I've got a scooter that needs a controller upgrade. It's got a box with 60V and 30A ratings. I'm going to upgrade all power wires on the bike but I'd like to mod the controller. Currently it is equipped with 12 RU75N08 Nchannel FETs. Anyone have experience like this and what fet's can I upgrade...

    Optimum number of POLES on Bigger BLDC motor

    I need some help understanding something about brushless DC motors. For the example I would like us to imagine the motor size is constant, Inrunner, aluminum housing, and between 25-35kW desired output. Something that an electric dirtbike might use. What are the factors that determine how many...

    A bit of theory help please

    Someone please explain me the deciding factors in a brushless DC motors max rpm? I mean, is it the controllers processor speed ? IF so, then does having fewer poles mean that the motor has higher rpm ability?

    Simple Tech Motor.

    Basic, Brutal, Brushed. I am curious if there is such a thing anymore? I don't mean an AGNI or something that costly either. I mean a real budget solution, but still capable of proper power levels and efficiency. Also, the simplest controller with high current capability that would match this...
