SINGLE PHASE FULLY ENCLOSED (IP 55) STANDARD ASYNCHRONUS MOTORS
Single-phase motors comply with the same standards as 3-phase motors in mechanical terms. The rotating field that creates the motor torque in single-phase motors is created with the help of 2 separate windings called the main and auxiliary windings. These motors can be selected with permanent capacitors or start-up + permanent circuit capacitors depending on the application they will be used in. Both types of motors have the following benefits and limitations.
Design with Permanent Circuit Capacitor
At this type of single-phase motors, the permanent circuit capacitor, which is active during operation, is connected in series with the auxiliary winding. Its power coefficient is high. Permanent circuit capacitor motors with a start-up torque between 50-80% of the nominal torque are especially used in applications that do not require high start-up torque, such as circular saws, drill machines, polishers, lawn mowers, pumps and fans.
