Terminology
Before we delve into the intricacies of the single-phase induction motors and let’s establish a foundational understanding of key terminologies :
- Induction Motor: An induction motor is an AC electric motor that operates on the principle of electromagnetic induction, using a rotating magnetic field to induce motion in the rotor.
- Stator: The stationary part of the motor containing coils that produce a magnetic field when energized.
- Rotor: The rotating component of the motor that experiences the rotating magnetic field generated by the stator, resulting in motion.
- Single-Phase: Refers to a type of AC power supply with only one sinusoidal voltage waveform.
- Starting Winding: A secondary set of coils in the motor used only during startup to provide an initial rotating magnetic field.
- Run Winding: The primary set of coils responsible for generating the continuous rotating magnetic field during the motor’s operation.
- Capacitor: An electronic component used to introduce phase shift and improve the motor’s starting and running performance.
Single Phase Induction Motors
Single-phase induction motors play a crucial role in various everyday appliances and small-scale industrial applications. These motors are widely used due to their simplicity and versatility. Single-Phase induction motors are a type of alternating current electric motor commonly used in a wide range of applications, especially in residential and small commercial settings.
