MOTOR
A motor is a device which
converts electrical energy into
mechanical energy.
Discovery of AC
MOTOR
First AC MOTOR was discovered in 1899.
1- Simple
2- Fixed speed and torque chracteristics
AC MOTOR PRINCIPLE
In a motor, the induction principle is utilized.
1- THE STATOR
The stationary section contain the windings.
2- THE ROTOR
The rotating section that contains the conductor.
TORQUE
When the carrying coil rotates , it produces the
torque in the coil.
Motor torque is affected by the voltage.
As voltage increases the torque increases.
DRAWBACKS
The high current when flow through the rotating
contacts , sparking and heating at those contacts can
waste the energy and shorten the lifetime of the
motor.
CONCLUSIONS
AC Motors operate through rotating magnetic fields
