Three-phase induction motors constitute a fundamental type of AC machine widely used in industrial applications. These machines rely on the principle of electromagnetic induction to generate torque and perform work. A three-phase induction motor consists of two primary components: a stationary stator and a rotating rotor. The stator houses three coils that are fed with a three-phase alternating current (AC). This creates a rotating magnetic field within the stator, which in turn induces currents in the rotor windings.
The induced currents in the rotor create their own magnetic field, resulting in an interaction between the stator and rotor fields. This interaction generates torque, causing the rotor to rotate. The speed of rotation is determined by the frequency of the input AC supply and the number of poles in the motor.
Multiple factors influence the performance of a three-phase induction motor, including its voltage rating, current capacity, power output, efficiency, and speed control capabilities. Understanding these characteristics is crucial for choosing the appropriate motor for a specific application.
