Answer:
K ∅ = 1.48 Wb
Explanation:
given data
EA=(82 V/A)
speed = 1,710 rpm
RA = 9Ω
Rad j = 6Ω
RF = 30Ω
voltage VT = 97 V
to find out
Kϕ for the motor in Wb
solution
first we get here shunt field current
shunt field current = ............1
shunt field current =
shunt field current IF = 3.233 A
and
now we get here induced emf for field current that is
induced emf = 82 IF
induced emf = 82 × 3.233
induced emf = 265.133 V
and induced emf EA is also express as
induced emf EA = K∅ω .....................2
EA = K ∅ ×
put here value
265.133 = K ∅ ×
solve we get
K ∅ = 1.48 Wb
