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

Former Member

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

    Is that the controller you are using?  Wow, that thing can support up to like a 6.6HP motor.

     

    I think you might have a problem with a controller that smart if it doesn't allow the motor to freewheel, it probably does regen braking and everything already, so breaking out your own load braking might be difficult.

     

    If using a large brushless motor like that can support, I suggest using a 3phase bridge and a motor contactor to output to your regen load.  Basically you'll want to disable the drive, not stop it or brake it, to allow the system to freewheel, then on the output of the 3phase bridge turn on the contactor to put the current through your load.

     

    You won't want to run the drive while diverting the current to your regen load though, otherwise you'll just power it from your motor drive.

     

    I'll draw up a diagram in a bit.
