What is an asynchronous motor?
Asynchronous motor is an alternating current (AC) electric motor, which uses an induced current in its rotor rather than physical power to create its rotary movement. Most electric motors rotate due to the interaction between electromagnetic fields created in the stator and engine rotor. In the asynchronous motor, the field generated in the stator winding is created by connecting them to the power supply. The field generated in the rotor is not delivered by direct introduction of the current, but rather through the transformer induction of the simultaneous courtesy of the stator adjacent electromagnetic field. Most larger alternating engines in industrial or home applications are asynchronous motors. The first is the stator, ie the external head frame in the shape of the head. The asynchronous engine stator has a number of windings or distributed along its inner surface, each containing a set of electrical connections on the outside of the frame. The second main part is a rotor - a cylindrical core, which fits close to the stator. CeilingThe engine that supplies the rotary work goes through the center or rotor and is supported by bearings at both ends. In the asynchronous motor, the rotor is either solid steel or consists of a series of parallel steel or copper bars without an electric input device.
Most alternating current engines rely on the polar relationship of separate electromagnetic fields generated in both parts of these parts for rotor spinning. In the asynchronous motor, the electromagnetic field of the stator is generated by the power supply connected to the stator winding. However, the rotor is not directly connected to any power supply, but rather develops internal electrical current by Induction. This induction is due to the close proximity of the electromagnetic field of the stator. This is exactly the same process used to generate current in the secondary transformer winding. The current produced in the rotor then generates its own electromagnetic field and rotor begins to rotate.
Asynchronous motor is ideal for heavy applications for its simplicity and roughness. The lack of other slip rings and brushes needed to supply the rotor energy is this type of engine one of the most reliable and effective alternating current designs. Asynchronous motors can also be used as generators if they run above certain speeds.
