    Hi Guys,

    I am trying to build a 3 phase controllor for a BLDC motor. However,
    going through the websites, not much help is found. I would like to
    know, where should i start? I am looking at a 3 phase driver TD310.

    Any replies are much appreciated.

    ** Do a search, you lazy ****.

    The part is widely available from on-line outlets.

  3. On the website, you can also find the complete
    schematics, parts lists, and PIC code for their motor control demo boards,
    which you can also purchase for a few hundred bucks. They also have good
    WMV tutorials and excellent app notes. I have spent several years off and
    on researching motor controls, motor design, and basic component
    characteristics, and I'm still learning. I am going to build a motor
    controller for my own experimental purposes, for three phase induction
    motors. If not for the fact I am going to research some unique custom wound
    motors, I would just buy what I needed. Let me know when you have learned
    enough to engage in a serious discussion, and we can talk. Until then, you
    need to do some research and hands on experimentation.

    You can also take a look to ATMEL website, they have
    documents with several implementations for controlling BLDC motors.
    Some of them are complex, others very simple.

    I have few questions for you and I can really help you out.

    1) What DC voltage do you have avaialble to run the motor?
    1A) where does this voltge come from (battery, generator, DC power
    supply capable of X amps? (fill in X))

    2) what is the expected power level of the motor? RPM and torque
    3) What is the load (fan, conveyer belt, toy car. etc)
    4) Does the BLDC motor have feedback elements (hall sensors, encoder,
    resolver, syncro)

    If you can answer these, I'll be glad to point you in the right direction.

    It might not be as simple as a phase control you might need to
    incorporate PID too if the speed is important.
