Single Phase Motor Basics
Single phase electric motors (sometimes called synchronous motors) have one permanent magnet rotor, which is wrapped around a second magnetic field piece. These motors use two of their own electrical charges to induce a current, which is why they tend to run better on higher temperatures. In a synchronous motor the poles of the magnets create a magnetic field, while the outer rings produce a second magnetic field. The current induced in this second field by the single magnet is then used to power rotation.
Single phase motors are a form of AC electric motor which uses electromagnetic principles to generate useful rotary power. They work much like that of wind-driven squirrel cage winding rotor, and other similar electric windup mechanisms. They also work in much the same manner as wind-driven synchronous motor, except that they are a little more simplified (and therefore cheaper) than conventional windup mechanisms.
This type of induction motor can be designed for either a permanent magnet or non-polarized operation. In order to understand this, I will first explain the different types of electricity, then how these different types of motors work. AC motors run on a DC input power supply, which is converted into a continuous AC voltage. There are four different types of electricity, namely, DC, AC, CR and NC.
