Halbach array Inrunner or Outrunner

Hello everbardy
How should magnets turn for an inrunner?
Do you have 2 different ways to mount magnets on below, with which should I choose an inrunner?


Examples are illustrated
By stator outside, which of the methods should be chosen for an inrunner?

Yours sincerely

As you haven't shown any curvature in your diagrams, there is no way to know what you mean by "outside".

In your first diagram, the magnetic field above the magnets is very strong; but below the magnets is almost non-existent. Inrunner or outrunner, the stator must face the strong side of the magnet array.

Hello Buk
Her you can see the inside rotor, it's these magnets that have to be mounted correctly for as strong a fake as possible.
See my rotor below!

Hope this appears to beers..
Do you have a suggestion for which Picture 1 or Picture 2 to be used

Hello everbardy
Is there anyone who can help me with a winding scheme for a BLDC motor Inrunner 4-Pole and 6-Tooth.
Something similar to the chart below.
But for an Inrunner 4-Pole and 6-Tooth ...

It will be a great pleasure if someone will help a winding drawing.

Yours sincerely

There is no single way to wind a motor that is "best". There are many variations. I don't mean to say that I know them, or that I understand each versions benefits and drawbacks, but...I know enough that I would only copy an existing successful design that matched the size and job that I wanted to motor to accomplish.

Halbach arrays exist and they do work, but, they make the permanent magnet array as a whole have fewer magnetic fields, so...why would you want that? Do you want a high pole-count motor, or a low pole-count motor, and why?

To answer your question, there is a strong magnetic field side on a Halbach array, and a weak side. The strong side needs to face the stator (which is populated with electromagnets that can be turned on and off). On an inrunner, the strong side of the Halbach array on the central rotor needs to face outwards, away from the axle. On an outrunner, the stator is in the middle and the rotor is on the outer rim, so...the strong side of the Halbach array on the rotor must face inwards, towards the axle.

There are several threads about rewinding motors, search for those in the motor section stickey...

Hello
Thank you very much for responding ..
But I wish that someone will help a winding drawing for an Inrunner 4-Pole and 6-Tooth.

Hello everbardy
How should I connect it Delta?

Would you like to be helpful with a schematic drawing on how to connect the above-mentioned BLDC Motor.

I think this is what you are asking for?

Thank you very much Buk
I will immediately test your proposal.
Comes back with report with BLDC Motor testing.
Thank you very much for your suggestion.)

Hello
Has mounted Stator in Delta.
Please see Delta Winding Configuration below.
View attachment 2
And with a compass under the stator, I could find that the winding was ok, by step numbers State 1 to State 6.


So stator winding and connected in Delta finds I'm right.
But the inrunner 4-pole rotor does not run??
Do the 4 magnets have something confidential?

Four Pole BLDC Motor.
Do they have 4 magnets something confident, does this rotor not only drive with the stator 6 Tooth ???

How are you driving it? Ie. What type of controller are you using?

Hello Buk
I am using YEP 120A Brushless ESC

And using the Arduino coder is attached below!

Do you have a suggestion for the codes?
You may want to correct the codes if you have a suggestion

Sorry, no. I'm a raw beginner myself in this field.

I'm hoping to learn from the responses to your questions from the experts .

Hello Buk
It is very nice that you look at the problem. Thank you very much for this!

But I can only hope that anyone can come up with suggestions so my Inrunner 4-Pole and 6-Tooth can run.
It will be very enjoyable. Have worked on the project for almost 2 years.

Yours sincerely
Monie
