What is AC motor and how it works?

How do AC motor work?

How AC Motors Work. The two basic parts of an AC motor are the stator (the stationary outer drum) and the rotor; the rotating inner portion of the motor which is attached to (and drives) the motor shaft. Both the stator and the rotor produce rotating magnetic fields.

How does a DC and AC motor work?

Both AC and DC motors use electrical current to produce rotating magnetic fields that, in turn, generate rotational mechanical force in the armature—located on the rotor or stator—around the shaft.

Where is AC motor used?

General uses for AC motors include pumps, water heaters, lawn and garden equipment, ovens, and off-road motorized equipment. In fact, many of the appliances, equipment and tools you use on a daily basis are powered by an AC motor.

Why do motors need AC?

An AC motor is a kind of electric motor that uses an electromagnetic induction phenomenon. An alternating current drives this electric motor. It is a type of electric current that periodically reverses direction and changes its magnitude continuously with time.

What are the 3 types of DC motors?

Main Types of DC Motors

  • Permanent Magnet DC Motors. The permanent magnet motor uses a permanent magnet to create field flux. …
  • Series DC Motors. In a series DC motor, the field is wound with a few turns of a large wire carrying the full armature current. …
  • Shunt DC Motors. …
  • Compound DC Motors.

What are the parts of AC motor?

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.

What is difference between AC and DC motors?

The most obvious difference is the type of current each motor turns into energy, alternating current in the case of AC motors, and direct current in the case of DC motors. AC motors are known for their increased power output and efficiency, while DC motors are prized for their speed control and output range.

Which is better AC or DC?

Alternating current is cheaper to generate and has fewer energy losses than direct current when transmitting electricity over long distances. Although for very long distances (more than 1000 km), direct current can often be better.

How do you control the speed of an AC motor?

At 60 Hz, the motor will run at 1800 RPM. A variable frequency drive controls the motor speed by using PWM (Pulse Width Modulation) to alter the power supply frequency that’s fed to the motor. There is typically no feedback coming back from the motor; although some drives uses back EMF as feedback.

What is the rotating coil of an AC motor called?

The coils which produce the magnetic field are sometimes referred to as the “stator”, while the coils and the solid core which rotates is called the “armature”.
