Many people will ask what are the drawbacks of variable frequency generators and how to choose them compared to traditional generators? Today we can analyze the advantages and disadvantages of variable frequency generators in detail:
Due to the power supply of the frequency converter, the motor can be started without surge current at very low frequencies and voltages. The various braking methods provided by the frequency converter can be used for fast braking to achieve frequent starting and braking. Therefore, under cyclic alternating forces, the mechanical and electromagnetic systems of the motor can lead to fatigue and aging of the mechanical and insulation structures.
Variable frequency motors can freely adjust speed within their speed range without damage. In general, variable frequency motors operate continuously at 100% rated load for 10% ≤ 100%.
The emergence of variable frequency motors mainly solves the problem of ordinary motors running at low speed and high speed. The low-speed operation of ordinary motors is a problem of motor heat dissipation and the strength of high-speed motor bearings.
Advantages of variable frequency motors:
Energy saving: Variable frequency motors can achieve more precise energy control and matching by adjusting the power frequency and motor speed, thereby reducing energy loss and saving energy.
Accurate control: The variable frequency motor can achieve precise control of motor speed and load through frequency converter control, meeting the requirements under different speed and load conditions, and improving the stability and reliability of equipment operation.
Small starting current: Compared to ordinary motors, the starting current of variable frequency motors is smaller, which can reduce the impact and impact of equipment on the power grid, and extend the service life of the equipment.
Low noise: The variable frequency motor operates with lower noise because it can adjust the motor speed and load matching, reducing mechanical vibration and noise.
Can adapt to different working conditions: Variable frequency motors can automatically adjust the power frequency and motor speed according to different load and speed conditions, and can adapt to different working situations.
Disadvantages of variable frequency motors:
High cost: The price of variable frequency motors is relatively high, mainly because they need to be used in conjunction with frequency converters, which are also expensive.
Technical support is required: The design, installation, and maintenance of variable frequency motors require certain technical support and professional knowledge. Improper operation may affect the operation and lifespan of the equipment.
High requirements for power grid quality: When using variable frequency motors, attention should be paid to the quality requirements of the power grid, such as voltage, current, electromagnetic interference, etc. If the requirements cannot be met, it may affect the operation and lifespan of the equipment.
In summary, variable frequency motors have obvious advantages in energy conservation, precise control, low noise, and strong adaptability, but at the same time, it is necessary to pay attention to their high cost, high requirements for technical support and power grid quality. Therefore, when selecting and using variable frequency motors, it is necessary to comprehensively consider their advantages and disadvantages in order to achieve the best efficiency and cost-effectiveness.
