    Wheel spin (how many revolutions?)

    The Newton meter torque drag is a great number to know but really how about something simple like my front wheel spins for 4 minutes and my Chinese 1000w dd rear hub motor will go 2 full revolutions before stopping with a one hand spin of the lucky wheel! How many revs for others out there...

    6 - 9 - 12 FETs ... Why 9?

    Ok I know what a hex bridge is ...3 phase drive ... So 6 FETs and if you double them or triple them you use 12 and 18 FETs but how are 9 FETs used? Is it in the free wheeling or what? Searching doesn't seem to find anything ANYWHERE ... I'm talking about motor controllers. Thanks in advance!
