    Hello,
    I taked motor from fan home heater,and small 6000rpm motor
    I attach this motors and at output of heater motor which i use as generator get only 0,5v how i can setup this so that can produce 220v?

    To use a motor as a generator, you will need one with a permanent magnet rotor.
    A fan heater motor is likely to be a shaded pole motor with no permanent magnetism and hence no output.

    It is brushless motor,it has no coil on rotor,if it has not coik or pernament magnet on rotor what it has?

    Look up shaded pole motor on Wikipedia.

    then it isn't suitable as a generator

    Only SOME motors can be used as a generator.

    A brushless motor with PM field should generate.
    AC and BLDC motors have three winding's/conductors so should generate 3phase.
    Many have a three phase or commutation controller built in, as per PC fans or HVAC ECM motors, in this case you will not see a generated output..
    Here is an example 3ph output of a back fed BLDC motor.

    What does the rotor look like or resemble?

    It looks like normal magnet rotor,vut it does not has magnets.

    Sounds like in induction motor but I don't see how it is 6krpm if ran off of 50/60Hz?

    I use DC motor to turn that "generator".

    Why are you using a DC motor to turn a "generator"? What do you hope to accomplish

    OK guys lets hold fire

    as I posted elsewhere ....
    pidja105, your descriptions are all very unclear.
    PLEASE draw a layout of how you expect everything to be connected ... what is powering the motor ( power source)
    what is the generator supposed to be powering ?

    NOONE else answer till this info is given by the OP
    I want to see if this is a pointless thread or it has some merit ??


    thanks
    Dave

    PS .... Ohhh and I have just deleted your other thread that was on the same topic as this one
