What Is a Single Phase Motor?
Generally, a single phase motor is the type of AC motor that uses a single alternating voltage. There are many types of single phase motors that are available in the market. These motors can be used for various applications. For example, these motors are used in refrigerators, freezers, and heaters.
These motors are relatively affordable and reliable. However, they are less efficient than three-phase power. For this reason, they are used for smaller loads in homes and offices.
The rotor of the single phase motor has a cylindrical shape. It has slots all over its surface. These slots are designed to prevent magnetic locking of the rotor and stator. This is done by means of interleading the pole windings.
The motor also has an auxiliary winding. This winding is connected in parallel to the capacitor. When the capacitor is turned on, it turns the auxiliary winding. These auxiliary windings have a high resistance. They create a phase difference between the fluxes that are produced by the rotor and the main winding.
These motors also have a starting switch. This switch opens when the motor reaches 80% of its full load speed. This switch is then removed from the circuit. It is important to note that these motors have a low starting torque.
The main winding is highly inductive and creates a magnetic field on the rotor. This magnetic field produces a force called F, which rotates the rotor.
The start winding is usually offset by 90 degrees from the main winding. When the motor reaches its full speed, the rotor is disconnected from the start winding. This enables the motor to operate as a transformer.waylead.com.cn
