Some issues about the Hall sensor signals for HBL2360

6 years 1 month ago #29529603 by poon2009
I am interested to use the Brushless DC controller HBL2360.

If my Brushless motor can only generate 2 analog signals,which are sine cosine waveform.
CH1 is sensor SIN.
CH2 is sensor COS.
File Attachment:


Can I still connect these 2 analog signals to HBL2360 directly?
OR should I need to convert them as 3 phase hall sensor signal?

Thanks

Your analog signal should be 0 to +5V non AC signal with our controllers.

No,I am asking about the Hall sensor signal which is generate from the brushless DC motor,
not the analog command signal.

Since the two hall sensor signal of brushless DC motor give a sinus and cosinus, a SIN/COS signal, that can be used to measure the absolute precision with surprising position form 0 to 360 degrees.
Just like the above of my figure.

So my question is could I just use these two hall sensor replace the 3-phase hall sensor,
and connect to the Hall sensor connector of HBL2360 directly.

Sorry for my bad English.

Thanks

No worries. As of currently none of our products support this.

However, we do a have a dual brushless controller that will be coming out later this year that will be able to do this.

FBL2360. Here is a link to the datasheet.

Also, if you can convert the 2 analog signals into 3 digital signals like Hall A, B, C, this will work too with all our products.

Thanks for your reply.

Do you have any solution or suggestion that I can convert SIN/COS signals to 3-phase hall sensor signals?

Thanks

Unfortunately, there isn't an easy way to do this. It may be best to wait until the FBL2360 comes out.

Perhaps we can continue the discussion via email as we can probably work out a solution if this is something we could try to work out together.
