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 
   	Thanks
