are three ways to count:
1. If the name plate
designate the
counter-electromotive
force constant Ke, then:
E=(Ke*n

2. If the name plate
designate the
counter-electromotive
force constant
E’(V/1000r/min), then:
E=E’*n
N
/1000
3. Iif the name plate does
not designate the above
parameters, then:
E=P/√3*I
In the above formulas: n
N
is the rated rotation speed,
P is the rated power and I
is the rated current.
