Three Phase brushless DC-motor connect Delta with 4-Pole and 6-Tooth

[monie jacobsen]

Hello YOU

Three Phase brushless DC-motor connect Delta with 4-Pole and 6-Tooth
Want guidance with winding stator please see below.

Would like GRUNDFOS ALPHA 2 to run on a solar cell with a maximum of 42V.
And want to use an ESC Controller to pump speed.

But after a lot of tests, I do not succeed!

Want to run pump the motor connected in DELTA.
Is there anyone here that will help with a drawing or description of how to connect stator as DELTA and the correct Phase and direction of the windings.

Regarding winding, I do not have the pumpe-motoren to run after repeated experiments!
Hope you will be helpful.


GUNDFOS ALPHA 2 - 4-Pole and 6-Tooth (Permanent Magnet)


De 4-Pole ses ovenfor!

With best regards

Hello everything

The motor is starting to run now!
So the winding on the stator is ok!

But have a big problem when starting the motor!
The motor must be started manually by pushing the rotor.
Or drive the motor fine up and down in turns.
Do you have a suggestion for how the motor can Start- up properly?

Has attached the Arduino codes I used to control the motor.
View attachment PumpeSystem.zip

Do you have a suggestion for the codes for a startup routine?
Can the codes make a startup routine to make the motor run correctly.
Hope you have a suggestion ...

Yours sincerely
Monie
