What are the three types of asynchronous motors

There are three main types of asynchronous motors: squirrel cage asynchronous motor, wound asynchronous motor, and three-phase asynchronous motor. All three are known for their economy and reliability, but specific applications need to be selected based on load requirements.

The three main types of asynchronous motors are as follows:

Squirrel cage asynchronous motor
Structural features: No excitation winding, simple structure, low cost, mature manufacturing process.
Performance advantage: High starting current but low starting torque, suitable for scenarios that do not require high starting torque (such as fans, water pumps, etc.).
Application field: Widely used in household appliances, small conveying equipment and other situations where control accuracy is not required.

Wound asynchronous motor
Structural features: The rotor winding is externally connected, and speed regulation can be achieved by adjusting the rotor resistance, resulting in a high starting torque.
Performance advantages: Adjustable starting current and speed, suitable for scenarios that require precise speed regulation or high starting torque (such as electric vehicles, machine tools, etc.).
Application areas: Mostly used in industrial equipment, automotive and other fields, especially suitable for occasions with high requirements for speed and torque.

Three phase asynchronous motor
Structural features: Powered by three-phase AC power, naturally generating a rotating magnetic field, stable operation, and high efficiency.
Performance advantages: high speed, high torque, easy maintenance, moderate cost.
Application field: It is the main force in the industrial field, such as medium-sized conveyor lines, compressors, polishing equipment, etc., suitable for medium load scenarios.

Summary: Squirrel cage and wound induction motors are mainly classified based on rotor structure, while three-phase induction motors are classified based on the number of power phases. All three are known for their economy and reliability, but specific applications need to be selected based on load requirements.
