A large number of motors are being used for general purposes in our environment, from household equipment to machine tools in industrial facilities. The electric motor is now an indispensable and indispensable source of power in many industries. The function and performance required for these engines are extensive. When attention is focused on the engine speed control segment, servo motors and stepper motors control their speed with a pulse train, while the induction motor and the brushless DC motor control the speed With an external resistance and / or DC voltage.

Principle of speed control
The speed of rotation N of an induction motor can be represented by expression (1). When the voltage applied to the motor increases and decreases, the slip s changes, then the rotation speed N will change.
N= 120·f ·(1-s)/P · · · · · · · · · · (1)
Where:-
N: Rotation speed [r / min]
F: Frequency 〔Hz
P: Number of poles of a motor
S: Slip
F: Frequency 〔Hz
P: Number of poles of a motor
S: Slip
