Induction Motor
An induction motor is a common type of electric motor. It operates on the principle of electromagnetic induction, where electrical energy is transferred to the rotor (rotating part) without a direct electrical connection. Widely used in various applications, induction motors are known for their reliability and simplicity in converting electrical energy to mechanical power.
The Induction motor is further divided into two types based on the rotor construction, namely:
- Squirrel Cage Motor
- Slip Ring Motor
Working Principle
Induction motors are the most common type of AC motor. They work on the principle of electromagnetic induction. When AC power is applied to the stator, it creates a rotating magnetic field. This magnetic field induces a current in the rotor (usually a short-circuited coil or squirrel cage). The interaction between the stator and rotor magnetic fields causes the rotor to rotate, driving the mechanical load connected to the motor.
Application
Induction motors are versatile and widely used in various applications, including household appliances, industrial machinery, pumps, fans, and conveyor systems. They are preferred for their simplicity, reliability, and cost-effectiveness.
- Household Appliances (e.g., Washing Machines, Refrigerators)
- Industrial Machinery (e.g., Conveyor Systems, Pumps)
- Fans and Blowers in Ventilation and HVAC Systems
- Electric Vehicles for Propulsion
- Water Pumps for Agriculture, Irrigation, and Domestic Use
AC Motor
AC Motors convert electrical energy into mechanical motion, featuring a stator, and rotor, and it have versatile applications due to their simplicity, reliability, and efficiency. AC motor has a wide range of applications ranging from a small electric device used in our homes to the huge machines used in major factories and industries.
This article explains AC motors, their construction, working principles, classifications (synchronous and induction motors), applications, advantages, and a brief AC vs. DC motor comparison.
