Re: [femm] current in slot conductors

Hallo Ahmad

 

maybe the following LUA code will be usefull to you

 

--set stator currents

 

 statorslotarea = 1.058784e-004
 turnspercoil = 10

 angle = 0

 phasecurrent = 30
 Jpeak = (((sqrt(2))*phasecurrent*turnspercoil)/statorslotarea)/1000000 -- div 1000000 to convert A/m^2 to MA/m^2
  
  JA=Jpeak*sin(angle)  
  JB=Jpeak*sin(angle -120) 
  JC=Jpeak*sin(angle + 120)

 

  modifymaterial("Conductor A1",4,JA) --This machine rotates anti-clockwise
  modifymaterial("Conductor B1",4,JB)
  modifymaterial("Conductor C1",4,JC)
  modifymaterial("Conductor A2",4,(-JA))
  modifymaterial("Conductor B2",4,(-JB))
  modifymaterial("Conductor C2",4,(-JC))

Subject: [femm] current in slot conductors

Dear all

I work in linear generator field. I want to consider an ac current
moving in the coils, so, how can I define this current value??

if the rms value is 20 A and the number of turns/slot = 25

so, the define current will be 20 A or 20*25 in each slot?

any suggestion is helpful

thanks a lot
