Smart Drive motor as a motor 'and' as a 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 magnets in the rotor.

As I still haven't figured out how to upload or attach a pdf in this forum I have converted the article I have on this motor into a series of jpgs.  So I will post them below.   To maintain image quality I have kept the file size large which means there will be only one page per post below.  Hope this helps explain why this is a more complex motor than a straight stepper.

Thanks

If your motor is like this one than it is just a simple 3 phase multipole motor and you may be able to drive it as this article suggests.

I cant recocile this with the spec data you posted:

Motor

Electronically commutated direct drive 3 Phase brushless DC Motor.

Motor resistance

                              Per Winding                    Phase to Phase

Phase 1                    1.3 ohms @ 20degC          2.6 ohms @ 20 degC

Phases 2 to 4            6.1 ohms @ 20 degC         12.2 ohms @ 20 degC

Phases 5 and 6          16 ohms @ 20 degC          32 ohms @ 20 degC

Where did thta data come from ?

Hi Michael,

The data I gave re resistance etc is from the service manual for the washing machine.  As mentioned, I can only provide the data on the internet as I am still on a steep learning curve, but I am learning a lot.

So from that article, can you, or others, suggest a controller that would suit?  I know that colecago suggested an option from the PML series.  My only reticence is the price.  As I am home-funded I am always on the lookout for the cheapest but still suitable option.  If you are aware of one this would be much appreciated.

Regards

Yeah, I'm kind of biased, I used to work at that company a few years ago and know the engineers there.  They are known for quality drives though.  The engineer that designed that does the AC and Brushless drives, as well as some of the higher power DC stuff.  He designed I think it was a 160V 1500A peak motor drive for an electric truck of his.

Hi

Nothing wrong with bias.  But in the instance that you weren't biased, and had a tight budget, is there another driver you would suggest?

Thanks

Simon
