    Hi,

    could someone guide me through the steps of how I would go about designing a bldc motor, knowing only the following requirements;

    a) Power 300W
    b) voltage 24V
    c) Torque 40 Nm
    d) RPM 180
    e) Max external dia = 254mm
    f) Max length = 90 mm

    So now I need to know;
    1) How many poles do I need? and why?
    2) How many teeth? and why?
    3) How many windings? and why?
    4) Of what diameter wire? and why?
    5) What dimension magnets? and why?

    Would much appreciate if you can get me started.
    I'm sure I can take it from there
    Thanks

    Sunil
