    Am vazut tocmai acum mesajul de pe site.
    Daca mai esti interesat de masina o dau cu 4700 de euro fara baterii. este loc destul pentru niste baterii cu plumb care nu sunt mai scumpe de 1500 de euro pt. 60-70km autonomie, sau daca vrei litiu sunt ceva mai scumpe.

    Buna ziua, am gasit , cu placuta supriza, site-ul si filmele de pe youtube. De ceva vreme caut informatii despre conversia unui smart.
    Sunt foarte interesat de proiect, dar cunostintele mele tehnice nu sunt suficiente pentru a discerne informatiile de pe internet, mai ales legate de controller. In principiu pare simplu, dar in realitate sunt 1000 probleme mici.
    Puteti sa ma ajutati?

    Hi On 45Kw motor build you said 14 in parallel 0.5mm wire what was the length of them please, what size the magnets or do you have drgs for motor parts.

    Also how much difference is there in ESC for DC motors and AC 3phase

  5. Keith says:

    Hi over the last 6 months we have spent 600nz dollars on trying to get you circuit for the brushless motor to work many circuit boards have been etched and built

    The mc33035 with Ir2103 and 12×12 voltage converter
    the mosfet are nchannel Ir1405n 55v 169A

    one for each high side and one for each low side (6 in all)

    we have protected the mosfets with a diode drain to source

    ON the bench the controller works ok you can stall the motor let it go and in runs with out problems

    The motors are cyclon 500watt and under load draw 20Amps on a push bike this was tested with a bought controller by the person who gave us the motors.

    Once the motor is coupled to a push bike it runs once then will not run again

    ON checking it all ways takes out (destroys ) one or two drivers

    Thanks Keith

  15. Amigo Lulian, the 45 KW brushless motor, can serve me as an electric generator ?, with 220V output of 50 HZ and 60 HZ, as much as three-phase or moniphasic ?.
