how the AC motor work and it's advantages?
Answers
Answer:
An AC motor is an electric motor driven by an alternating current (AC). The AC motor commonly consists of two basic parts, an outside stator having coils supplied with alternating current to produce a rotating magnetic field, and an inside rotor attached to the output shaft producing a second rotating magnetic field

♣️How does an AC motor work?
Unlike toys and flashlights, most homes, offices, factories, and other buildings aren't powered by little batteries: they're not supplied with DC current, but with alternating current (AC), which reverses its direction about 50 times per second (with a frequency of 50 Hz). If you want to run a motor from your household AC electricity supply, instead of from a DC battery, you need a different design of motor.
In an AC motor, there's a ring of electromagnets arranged around the outside (making up the stator), which are designed to produce a rotating magnetic field. Inside the stator, there's a solid metal axle, a loop of wire, a coil, a squirrel cage made of metal bars and interconnections (like the rotating cages people sometimes get to amuse pet mice), or some other freely rotating metal part that can conduct electricity. Unlike in a DC motor, where you send power to the inner rotor, in an AC motor you send power to the outer coils that make up the stator. The coils are energized in pairs, in sequence, producing a magnetic field that rotates around the outside of the motor.
♣️Advantages
Ac motors are brushless and develop a higher torque. The speed and the power developed can be varied with the aid of a controller. They can operate at higher voltages hence reducing the size of wire. Since there is no commutator, there are no brushes hence no sparking. Poly phase induction motors are normally used in high performance vehicles such as EV West conversions, Tesla, Chevy Bolt, and Nissan Leaf to name a few. Regenerative braking is now a standard feature on all AC powered electric vehicles.

DC motors require less sophisticated electronics as controls used are pretty straightforward in design. Unlike AC, DC powered EV’s do not require precision programming of the controllers
