    i am working on DSP chip number IR2130 to design controller for bldc motor,

    at first the PWM controller then the chip ir2130 is connected to the 3-phase inverter.

    am i doing the right thing or i have to add other circuits also.


    There is another chip TMS320LF2407A, that i have searched on the internet but it is very complex to understand, is it necessary to connect this chip with my controller.


    Thanks.

    You seem a little lost. IR2130 is a mosfet driver for a three phase bridge, and the TMS320LF2407A is a DSP microprocessor. Where are you getting the pwm from?

    You didn't answer my question, what generates the pwm?

    A micro controller or DSP is not needed to control a BLDC motor with hall sensors, like you were talking about in your other thread. It can be done with a chip and the mosfets.
    The chip, MC33035 is very inexpensive to buy and old enough to be well proven to work.

    TMS320LF2407A generates the pwm.

    Then you need both the TSM320 and the IR2130.

    just connect 3-phase inverter with MC33035 chip and thats it..? any other components need to connect with it...... please don't get frustrated.

    thanks,

    Not frustrated just don't understand why some one asks for help, but won't do what is suggested.

    Nothing this technical can be explained in 140 characters or less. You have to do the reading to understand what is needed. Don't think you have figured out yet what a BLDC takes to make it operate.

    When people on two different sites(that I know of) tell you the same thing and you go off on a tangent, what would you do? People on both sites will help, but you need to help yourself too.
