How does the speed of an induction motor changes when mains frequency increases?Question 1Select one:a.decreasesb.increasesc.does not change
Question
Solution 1
The speed of an induction motor is directly proportional to the frequency of the power supply. This relationship is described by the formula:
N = 120f / p
where: N = speed of the motor in RPM (revolutions per minute) f = frequency of the power supply in Hz (hertz) p = number of poles
