Ordinary three-phase asynchronous motor;
Ordinary three-phase asynchronous motors usually adopt the traditional voltage-frequency speed regulation method. Its speed is mainly controlled by the voltage and frequency of the power supply, and its speed regulation range is relatively narrow.
Its structure is relatively simple and its cost is relatively low. Widely used in general industrial equipment and household appliances, such as fans, pumps, compressors and so on.
Ordinary three-phase asynchronous motor has good performance and reliability in traditional industrial applications, but compared with broadband three-phase asynchronous motor, its speed range and accuracy are limited.
1. Advantages:
Low cost: The design and control technology of ordinary three-phase asynchronous motor is relatively simple, so the cost is low.
Good reliability: after years of application and verification, the performance of ordinary three-phase asynchronous motor is stable and reliable.
Widely used: Ordinary three-phase asynchronous motors are widely used in general industrial equipment and household appliances, such as fans, pumps, compressors and so on.
2. Disadvantages:
Narrow speed regulation range: The traditional common three-phase asynchronous motor can only carry out simple voltage and frequency speed regulation, and the speed regulation range is relatively narrow.
Limited accuracy: Compared with broadband three-phase asynchronous motor, the speed and torque control accuracy of ordinary three-phase asynchronous motor is lower.
Slow dynamic response: the dynamic response speed of ordinary three-phase asynchronous motor is relatively slow, and it is impossible to realize rapid acceleration and deceleration.
When choosing broadband three-phase asynchronous motor and common three-phase asynchronous motor, the following factors can be considered:
Speed control requirements: If your application requires a wide speed range and precise speed control, a broadband three-phase asynchronous motor may be more suitable. It can achieve accurate speed control by adjusting the frequency.
Cost budget: Broadband three-phase asynchronous motor is usually more expensive than ordinary three-phase asynchronous motor because it adopts advanced control algorithm and frequency converter and other equipment. Therefore, if your budget is limited, ordinary three-phase asynchronous motor may be a more economical choice.
Application scenario: Different application scenarios may have different requirements for the performance and characteristics of the motor. If your application is general industrial equipment or household appliances, ordinary three-phase asynchronous motors are usually enough. However, if your application needs high-performance speed control, such as wind power generation, machine tools, electric vehicles and so on. Broadband three-phase asynchronous motor may be more suitable.
Technical requirements and reliability: The installation, debugging and maintenance of broadband three-phase asynchronous motors usually require certain professional knowledge and skills. If your team has the corresponding technical ability and high requirements for high performance and precise control, broadband three-phase asynchronous motor may be a feasible choice. Ordinary three-phase asynchronous motor has stable and reliable performance in traditional industrial applications.
