Smart Drive motor as a motor 'and' as a generator?

Former Member
Former Member over 11 years ago

Hi

I am working on a project where I want to use a Smart Drive Motor (Found in Fisher and Paykel washing machines, and also in LG and Samsung machines) as a motor, and then as a generator.  The problem I am having is getting the motor to work.  It needs a motor controller, but I haven't found anything in a post or anywhere that provides a list of parts and schematic. I am hoping to have the capabiltiy within the system to switch between a motr and a generator.

Given my level of capability I would really like a start to end project description.

 

Does anyone know of such a description or is anyone able to help me out with building this project?

 

Thanks

 

Simon

    Hi I have drawn up the schematic as I see it at this point. Points to note are that the motor is in a 3-phase star configuration. I have also drawn in a relay to allow to switch between the motor and generator…

    Hi Michael, Due to me still being a newbie in this area, I can only offer up the info I have gleaned from the internet. I think the reason this is not a simple stepper is because of the arrangement of…

    What do you want the generator to do?  Charge a battery or something?

     

    Basically look for a 4Q motor drive that can do regeneration.  Regeneration/regen/regen braking basically dumps the energy back onto the input line

    Hi

    At this stage I actually want the generator to do as little as light some bulbs.  I am working on prototyping a new type of transmission system, instead of a gearbox.   So I want to run the motor and then switch it over to a generator.  As mentioned in the original post I would really like to get a full description of what I need to set this up, because, whilst I am learning as quickly as I can, this is outside of my realm of expertise, so specifics and details are what I need.  I am not even sure what a 4Q is.

     

    Cheers

     

    Si

    Sorry, had some bad ideas here.

     

    I think you might be able to accomplish this with an h bridge used in a non standard way. I'll look into more tomorrow and post.

    Hi

    It is sort of like an electric car, except that I anticipate that I would run the motor up to a set speed, and then switch over (relay?) to the generator mode and keep it that way as the input energy (wind turbine or similar) would then keep the generator turning, via the mechanical transmission, which is what I am trying to demonstrate.

     

    I look forward to your further comments.

    One big question first, what size and type of motor? That will matter.
