Circumference Formula C = 2πr
Area of a circle A=πr²
Pressure formula Pressure = Force/Area or P = F/A
60 x F /( N/2) where F(frequency is Hz) N is the
number of poles
RPM formula
Example: what is the rotating speed of a three phase
30 HZ 6 pole motor?
60 x 30hz = 1800 1800 •/• 3 poles = 600RPM
Time constant formula in T = RC where T is time in sec. R is Resistance and C is
resistive capacitive circuit Capacitance which is probably is in microfarads
Time constant formula in a T=L/R Where T is time in seconds, L is inductance in
resistive inductive circuit henries and R is reaistance
formula for frequency f=1/T where T is time(period) in seconds
