Three-phase induction motors constitute a fundamental type of rotating 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 circuits 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 website 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 identifying the appropriate motor for a specific application.
Stepping motors
Stepper motors are electromechanical actuators that convert electrical energy into precise rotational motion. Characterized by their ability to incrementally rotate in discrete angles, they offer a high degree of accuracy.
