how does ac motors spin in one direction if its powered by alternating current , and what is single phase and 3 phase alternating current ?
In: 1
AC motors spin in one direction because of the way the internal components are wired. The alternating current (AC) flows in a wave pattern, and the motor takes advantage of this wave pattern to create a rotating magnetic field. The components inside the motor are wired in such a way that the rotating magnetic field causes the motor to spin in one direction. Single phase alternating current is a type of AC power supply that uses a single phase. This means that the current alternates in one direction, and then reverses direction. Three phase alternating current is a type of AC power supply that uses three phases. This means that the current alternates in three directions, and then reverses direction. This allows for a more efficient power supply, and is used in many industrial applications.
