    Induction Motor: Working Principle, Features and Advantages

    An induction motor refers to an AC motor that relies on electromagnetic induction between the stator and the rotor to induce a current in the rotor to realize electromechanical energy conversion. The stator of the induction motor consists of three parts: the stator core, the stator winding and the frame. Under normal circumstances, the rotor speed of the induction motor is always slightly lower or slightly higher than the speed of the rotating magnetic field, so it is also called an "asynchronous motor".

    Single Phase vs. Three Phase Induction Motor

    Induction motor for sale, also known as "asynchronous motor", is a device that puts the rotor in a rotating magnetic field and obtains a rotating torque under the action of the rotating magnetic field, so that the rotor rotates. The rotor of an induction motor is a rotatable conductor, usually in the shape of a squirrel cage. According to the type of alternating current, there are single phase induction motors and Three phase induction motors. So what is the difference between them? This is mainly reflected in the following aspects.

    What is a Single Phase Motor?

    Single phase motors generally refer to low-power single phase asynchronous motors powered by a single phase AC power supply. It is also called a single phase induction motor. This kind of motor usually has two phase windings on the stator, and the rotor is of ordinary squirrel cage type. The distribution of the two phase windings on the stator and the different power supply conditions can produce different starting characteristics and operating characteristics.
    Single phase motors have a large production volume and are closely related to people's daily lives. Especially with the improvement of people's living standards, the consumption of single phase motors for household appliances is also increasing.

    Induction Motor Price List

    Compared with other motors, the ATO induction motor has the advantages such as simple structure, convenience in manufacture, use and maintenance, high operational reliability, light weight, low cost. Taken the ATO three-phase induction motor as an example, compared with the DC motor with the same power and speed, the former weight is only half of the latter at one-third cost. It also has the load characteristics of constant speed that can satisfy machinery driving requirement of a majority of industrial and agricultural production. Its limitation is that due to the poor speed controlling performance caused by the fixed slip between its rotate speed and the synchronous speed of its rotating magnetic field, so it is not so economic or convenient as direct current motor under the usage occasion that requires a wider range of smooth speed control such as rolling mill, winding engine, large size machine tool etc. In addition, induction motors draw reactive power from the power system during the operation, resulting in the deterioration of power factor of power system. Therefore, on the occasion of high power and low speed such as driving ball grinding mill and compressor, using synchronous motors is more reasonable.
