I am trying to do a project on electrical engineering which involves design of electrical circuitry for a soot blower arrangement.i am having problems in designing a motor( 3phase induction motor). i know how to calculate the rotor parameters,losses, efficiency,etc. i am told that i have to find...
sorry for the delay in responding
the value i get for relative permeability is 238734.802
i will scan and attach the method that i have followed to solve the prob till now.
using f=BLI i found B=100T
next i used S=L/mew0*crosssectional area of air gap(L=10mm,c/sarea airgap=piD=3.14*0.001)
=2533029.59A/wb
next using H=IN/L(I=100mA,N=50,L=15mm this assumed)
=333.33A/m
but when i go to find relative permeabilty i am getting a...
F=BLI
where B is flux density,L is length of conductor, and I is the current in the conductor.
magnetic field density=magnetic flux/c/s area
magnetic flux=mmf/reluctance
& reluctance=lenght of airgap/mew0 * c/s A
a zobel network consisting of a capacitor C and resistance Rc is connected in parallel to a speaker of inductance L and resistance Rl.show that frequency at resonance =1/2pi*Sq rt 1/LC(Rlsquare-L/C ÷ Rc square-L/C)
i have begun by equating the reactive components of the branch currents...
i was solving a prob the foll prob on electrical resonance.
a resistance is connected in series with an inductor which inturn is connected to 2 capacitors(capacitors are in parallel w.r.t each other, and one of them is trimming capacitor).the circuit is now connected to a relay whose...
