Hi all

  i am working on a BLDC Motor .

I am confused with what angle i should define to orient the material of magnet .i have total 10 magnets in the rotor.

I searched in so many activitied ,where it is given 10and -10.But in my case , i am taking full model(10 magnets) because it is not working with periodicity for 10 pole machine 

Now what angles rto define .


When i say 10 and -10 what exactly that mean ..with respect to which line/axis it is measured

A permanent magnet is characterized by remanent induction (Br). To represent a permanent magnet in Flux we need:

  • The type of magnet (linear or nonlinear)
  • Magnetic proprieties (remanent induction and permeability)
  • The orientation of the magnet (sense of the remanent induction on the magnet)

From Flux if you want to see the orientation of the magnet, from the tab “physics” select ‘display arrow on the magnet’. This give you an idea about the sense of the remanent induction inside your magnet.

In your case, to define the orientation of the magnet, you can create a coordinate system in each magnet, and assign a value of the angle according to the coordinate system that you have created.


Best regards.
