As we all know, the motor is the most widely used in agricultural production of a kind of electrical equipment, such as guillotine, rice mill, mill and other agricultural special equipment are through the motor power output. However, due to the poor working environment of agricultural machinery, problems often occur when agricultural machinery is used, and motor burning is a common phenomenon. Therefore, in recent years, in order to further ensure the normal operation of agricultural machinery, many motor control manufacturers have updated and iterated the products, of which the centrifugal switch is a key component.

The centrifugal switch is a control component that all motors cannot do without. As early as the 20th century, the mechanical centrifugal switch has been widely promoted in the market, its core working principle is to determine the speed of the motor through its own centrifugal force, but because it is a mechanical structure, it has been a defect of safety, poor stability and short service life, which has not been solved for many years. It was not until 2007 that Fuxing Weiye launched electronic centrifugal switches that motor control began to move towards the era of intelligent control.

The electronic centrifugal switch is to determine the starting speed of the motor by sampling the current, voltage, phase and other parameters of the motor, which solves the poor safety performance of the mechanical centrifugal switch at the same time, and has the advantage of convenience and easy operation, which improves the working performance of agricultural machinery and reduces the cost of use, and has become the first choice for many agricultural machinery motor intelligent control. Next, let's talk in detail about the advantages of electronic centrifugal switches compared to mechanical centrifugal switches, and why agricultural machinery should choose special electronic centrifugal switches.

First, higher security

As we all know, the working environment of agricultural machinery is relatively harsh, such as the use of the mill environment is crushed crop straw, water droplets exist in the water pump environment, so the safety performance of the centrifugal switch is a problem that all manufacturers need to consider. However, because the mechanical centrifugal switch is a mechanical structure, there are sparks and contacts, and the contacts are easy to stick to oil stains, dust, etc., during actual use, which will not only lead to motor control failures, but also may cause fire or even explosion in serious cases, and the safety of the motor is not effectively guaranteed.

The electronic centrifugal switch prevents this situation from the structure, is not mechanical structure, no contact, will not produce sparks in the working process, and is not affected by any dust, oil, water, powder, etc., can work normally in harsh working environment, ensure the safe operation of the motor, not only improve the efficiency of agricultural machinery but also ensure the safety of the motor.

Second, wider versatility

Secondly, the use environment of agricultural machinery is very different, and its supporting centrifugal switches are naturally diverse, which requires great production costs. For example, mechanical centrifugal switches need to choose different models according to the number of poles, frequency and bearing size of the motor, and the production cost is great and the management is not convenient. The electronic centrifugal switch is a good solution to this problem, its versatility is wide, regardless of the motor frequency, the number of electrodes, an electronic centrifugal switch can be applied to all motors, greatly reducing the factory production costs and improve the factory production efficiency.

Third, stronger stability

The stability of agricultural machinery is an important guarantee for its long-term use. In complex working environments, centrifugal switches with good stability are needed to ensure the normal operation of equipment. If the stability of the centrifugal switch is not good, it often leads to the failure of agricultural machinery. Compared with the mechanical centrifugal switch, the batch consistency is better, the stability is stronger, the disconnected speed can be effectively controlled at 75%, and can be frequently started and stopped, to further ensure the reliability of agricultural machinery equipment, there will be no load or mechanical switch can not be opened, and so on, reducing the many hidden risk sources of the motor.

4, small size, good heat dissipation performance

Agricultural machinery is prone to heat in normal operation, if the heat dissipation performance is not good, it will lead to overheating of the equipment. Therefore, the heat dissipation performance of the motor is also extremely important. The electronic centrifugal switch is updated by technology, so that the electronic centrifugal switch volume design is smaller, does not occupy the internal space of the motor, can shorten the motor shaft, and can reduce the temperature rise by 5-10 ° C. Unlike the mechanical centrifugal switch pole, which takes up space, the void in the motor is small and cannot provide good heat dissipation. Therefore, the heat dissipation performance of the electronic centrifugal switch is better.

5. Long service life and high cost performance

Although the mechanical centrifugal switch is cheaper than the electronic centrifugal switch, its switching life is less than 100,000 times, and the electronic centrifugal switch life can reach more than 1 million times, far more than the mechanical centrifugal switch. In addition, the electronic centrifugal switch can reduce the overall operating costs of the motor (such as reduced materials, reduced working hours, improved efficiency, repair rate within 0.05%, low burning probability, less waste), greatly improve the customer's market competitiveness, is a comprehensive cost-effective product.

In summary, the performance of the electronic centrifugal switch is better than the mechanical centrifugal switch, the electronic centrifugal switch is the first choice to solve the safety performance of agricultural machinery and improve production efficiency, only the selection of excellent performance of the electronic centrifugal switch can further ensure the safe operation of agricultural machinery. It can be said that the electronic centrifugal switch developed and launched by Fuxing Weiye can greatly improve the application performance of the centrifugal switch, improve the performance of agricultural machinery products, and help the agricultural machinery industry is very great.

In addition, the frequency conversion control board series, frequency converter series and other products developed and launched by Fuxing Weiye can further improve the control performance of the motor and adapt to various working environments of agricultural machinery.
