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 windings 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.
There 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 identifying the appropriate motor for a specific application.
Stepper motors
Stepper motors are electromechanical actuators that convert electrical energy into precise rotational motion. Characterized by their ability to stepwise rotate in discrete angles, they offer a high degree of accuracy.
