The advantage and feature of Aysnchrnous motor

Feature

1.Simple structure: composed of basic components such as stator, rotor, winding, etc., with low manufacturing and maintenance costs.

2Speed elasticity: The speed can be adjusted with changes in load, and the slip rate is usually between 1% and 5%, suitable for dynamic load scenarios such as fans and pumps.

3High reliability: The squirrel cage rotor structure does not require slip rings or external resistors, making maintenance convenient and with a low failure rate.

Cost advantage: Compared to permanent magnet motors, asynchronous motors do not require rare earth materials and are suitable for large-scale production.

Advantage

1. High efficiency: By adjusting the speed through a frequency converter, the cubic relationship between flow rate and energy consumption can be optimized (such as for fans and pumps).

2. High overload capacity: Short term overload can reach 4-7 times the rated current, suitable for electric vehicle drive systems.

3. Widely used: accounting for over 90% of the industrial asynchronous motor market, covering scenarios such as lifting machinery and machine tools.

4. Fast dynamic response: Adopting three-phase asynchronous technology, the dynamic performance is superior to traditional DC motors.

The introduction of Asynchrnous motor

Asynchronous motors are divided into two forms according to their rotor structure: squirrel cage asynchronous motors and wound asynchronous motors.

An asynchronous motor that operates as an electric motor. Because its rotor winding current is induced, it is also known as an induction motor. Asynchronous motor is the most widely used and required type of motor among all types. About 90% of electric powered machinery in various countries are asynchronous motors, with small asynchronous motors accounting for over 70%. Asynchronous motors account for a significant proportion of the total load in the power system. In China, the electricity consumption of asynchronous motors accounts for over 60% of the total load.

Asynchronous motor is an AC motor, and the ratio of its speed under load to the frequency of the connected power grid is not a constant value. Induction motor is an asynchronous motor with only one set of windings connected to the power supply. Induction motors can generally be referred to as asynchronous motors without causing misunderstandings or confusion. The IEC standard states that the term "induction motor" is actually used as a synonym for "asynchronous motor" in many countries, while other countries only use the term "asynchronous motor" to represent these two concepts.
