    DIY motor from a motorcycle magneto stator?

    The plate is too thick (0.7mm). Very large iron loss. http://electrotransport.ru/ussr/index.php?topic=36552.0;topicseen

    Motor torque math

    For comparison, in this case, use Km and sKm! Km=Kt/Rph^0.5 sKm=Km/m Kv and Kt is necessary only to determine the proportion between the voltage and the current.

    6000 Watt continous 14.000 rpm at 44v

    If use 14000rpm (max), then: 2000-2400W continious only; efficiency bad.

    What iron loss in a small block at high speed? 2000..3000..4000..5000..6000..7000..8000rpm Anyone conducted these measurements?

    Torque-Sensor Motor w/ Sine-Wave Controller Build

    For hubmotor does not really matter. For mid drive it is not very good. Because most likely loss in iron of motor speed more 1500rpm (before the gear) become too great.

    Torque-Sensor Motor w/ Sine-Wave Controller Build

    Thanks for the info. --- Yet I wonder how many watts consumes not loaded motor? It is desirable at high speeds. V + A + rpm (or km/h + wheel diameter).

    Miles' 125mm inrunner design

    For 5 seconds, almost no cooling system does not have time take a lot of heat, so we can assume (in some approximation) that the adiabatic process. Suppose that, for example during this heating period (5 seconds) at 50 degrees сelsius.

    Open Source CA alternative on German pedelecforum available

    crossbreak, thanks for info. They can not directly constrain the phase current, but may limit the battery current, and if they can do so quickly enough can be said that practically the device of this type can limit the phase current. --- Little oftopit: So, I will only fit kelly, because: phase...

    Open Source CA alternative on German pedelecforum available

    OK, ask the question another way. if I use "Forumscontroller" with "Greentime controllers" then work function: -current mode throttle control, -battery and phase current limiter?
