product details:

The AC induction motor reigns supreme in the world of electric air compressors. Renowned for its durability, reliability, and low maintenance, this workhorse tirelessly converts electrical energy into the mechanical force needed for air compression. Here’s a detailed breakdown of its inner workings:

Core Components:

• Stator: The stationary outer part of the motor that houses the electromagnets. It consists of a metal frame with a laminated core made of thin steel sheets to minimize energy losses due to eddy currents. Embedded within the core are windings – tightly packed coils of insulated copper wire.
• Rotor: The rotating inner part of the motor, mounted on a shaft. There are two main rotor designs in AC induction motors:
  • Squirrel Cage Rotor: The most common type, featuring aluminum or copper bars arranged around the circumference resembling a squirrel cage. These bars are shorted together at the ends, forming a closed loop for induced current to flow.
  • Wound Rotor: Less common, but offers some advantages like variable speed control. It has windings on the rotor similar to the stator, connected to slip rings that transmit current through brushes.

Working Principle:

1. Energizing the Stator Windings: When you connect the AC induction motor to a power source (usually 110V or 220V AC), the stator windings become energized.
2. Creating a Rotating Magnetic Field: The alternating current flowing through the stator windings creates a constantly rotating magnetic field. This magnetic field sweeps around the inside of the motor at the same frequency as the AC power supply.
3. Induction of Current in the Rotor: According to the principle of electromagnetic induction, a moving magnetic field interacting with a conductor induces an electric current in that conductor. In the AC induction motor, the rotating magnetic field from the stator cuts across the bars or windings of the rotor, inducing an electric current in them.
4. Electromagnetic Force and Rotor Movement: The induced current in the rotor, in turn, creates its own magnetic field. This rotor’s magnetic field interacts with the rotating magnetic field of the stator according to the principle that like magnetic poles repel and unlike poles attract. This interaction results in an electromagnetic force that tries to propel the rotor in the same direction as the rotating magnetic field of the stator.
5. Continuous Rotation: However, the rotor can never quite “catch up” to the stator’s rotating magnetic field. This difference in speed is called slip. The slip ensures that the induced current in the rotor is always present, maintaining the electromagnetic force that keeps the rotor spinning.
