An AC induction motor, is a type of electric motor that operates on alternating current (AC) power. They are widely used in various applications due to their efficiency, simplicity, and ability to generate consistent power.
AC induction motor is ideal for uni-directional, continuous operation in conveyor systems, requiring a capacitor and AC power supply. AC induction motors offer high power and efficiency, with longer power bands, higher RPM, regenerative braking, and easy reversing without contactor pre-charge resistors or diodes.
Working Principle of an AC Motor
The basic working principle of an AC Motor mainly depends on magnetism. The basic AC Motor includes a wire coil & two permanent magnets nearby a shaft. Once an alternating current is supplied to the wire coil, then it turns into an electromagnet that produces a magnetic field. This motor includes two essential parts like stator and rotor. This stator includes a wire loop, a solid metal axle, freely moving metal parts that conduct electricity, a coil, a squirrel cage, etc.
In the stator of an AC motor, we can transmit the power toward the external coils to make up the stationary part like the stator. The coils of wire can be activated in pairs, in series to generate a magnetic field that turns approximately the exterior of the ac motor.
Rotor balances within magnetic field, generating electric current through electromagnetism law due to rotation.
If the conductor used in this is a wire or a ring, then current supplies in a loop around it, or if the conductor is a solid metal piece simply, then eddy current will flow around it. The current induced can generate its magnetic field & based on another electromagnetism law, the rotary magnetic field will rotate also. Once the magnets interact, then the coil of wires & shaft will start to turn the motor.
Following are the reasons, why minimal maintenance needed for this motor type:
- The rotor windings are shorted to form a squirrel cage.
- There are no commutator or slip rings to service (compared to the DC motor).
- There are no brushes to replace.
