I have been deeply involved in the research and development of brushless motor control panel for 15 years, and I have taken over a large number of supporting projects for industrial ventilation, outdoor exhaust and equipment cooling fans. Many enterprises will encounter common problems when choosing the speed control board of low-voltage brushless fan: the equipment needs to run continuously for 24 hours, and the long-term work with load is prone to problems such as hot motherboard, speed control failure, shutdown error and shortened service life.

I have been deeply involved in the research and development of brushless motor control board for 15 years, and I have been in contact with a large number of industrial automation, workshop ventilation and outdoor exhaust equipment manufacturers. Many engineers will encounter a common problem when selecting the type: the parameters of the control panel of high-pressure brushless fan in the market look similar, but there is a great gap in the operation of the machine, and there are frequent problems such as starting jamming, speed drift, overheating of the fuselage, and burning of the board for no reason. In fact, people in the industry know that it is meaningless to simply look at the power parameters. The core that really determines the stability and durability of the control panel is the accuracy of the FOC control algorithm and the adaptability to high and low temperature environments, which is also the core technical barrier of high-quality mass customization manufacturers.

I have been deeply involved in the research, development and customization of motor control panels for many years, and I found that many industrial equipment manufacturers easily fall into the configuration misunderstanding when selecting the control panels of high-voltage brushless fans. Many general control panels are single in driving mode, simple in protection function and poor in communication compatibility,

I have been deeply involved in the brushless motor control board industry for 15 years, and I have come into contact with a large number of customized pit-stepping cases of equipment manufacturers. The general power boards purchased by many enterprises in bulk seem to be cost-effective. After landing, problems such as speed fluctuation, excessive noise, overheating and burning of motors frequently occur, and even production lines will be shut down and batch rework will be caused in serious cases. In the final analysis, the working conditions of industrial fans are complex and the parameters are special, so the template general scheme can not be adapted at all. In order to make a stable, adaptive and low-cost brushless fan power board, we must rely on the complete set of standardized customization processes of the source manufacturer. This paper takes the landing process of Shenzhen Hengtai Innovation as an example to completely dismantle the whole process of industrial customization.

I have been deeply involved in the brushless motor drive control panel industry for 15 years, and I receive a lot of customer selection consultation every day. Many enterprises only pay attention to the basic driving function when purchasing the fan control board, ignoring the scheme adaptability, working condition compatibility and protection configuration, which leads to problems such as equipment voltage fluctuation error, startup failure, high temperature downtime, locked rotation and burning. In fact, reliable source manufacturers will provide subdivision drive solutions and a full set of intelligent function configurations according to different scenarios of home, business and industry. In this paper, combined with the mature landing case of Shenzhen Hengtai Innovation, the mainstream drive scheme, core functions and hardware advantages of professional manufacturers are dismantled in detail to facilitate accurate selection.

I have been deeply involved in the research and development of brushless control panel scheme for many years, and I have received technical consultation from a large number of industrial fan equipment manufacturers. The most frequently asked question is whether to choose square wave control or FOC magnetic field directional control for 300W industrial fans. In order to reduce the cost, many enterprises blindly choose the low-cost square wave scheme in the early stage, but in the later stage, they frequently encounter the problems of loud fan noise, unstable speed and high energy consumption. Reworking and changing the scheme will increase the cost. 300W is the golden power section of industrial fans. It is very important to choose the right control scheme if you want to give consideration to equipment stability, operation experience and cost performance. Today, with a real landing case, I will tell you the selection logic and application scenarios of the two schemes.

I have been deeply involved in the brushless motor drive control industry for more than ten years, and I have been exposed to a large number of customized projects of high-power control panels supporting industrial fans, machine tools and new energy.

I have been deeply involved in the brushless motor control board industry for more than ten years, and I often encounter customers' doubts: Why can the price difference between manufacturers reach several times when the appearance and size of the brushless external rotor fan control board are similar? Many purchases only compare the unit price, and do not understand the differences in internal power configuration, control scheme and protection level, so it is easy to have low-cost purchases, high-frequency failures and production stoppage losses. The quotation of control panel is never based on appearance pricing, and the core gap is concentrated in four dimensions: power level, FOC control scheme, protection function and mass production quality. Today, combined with the practical experience of the industry, we will help you thoroughly clarify the logic of price difference and accurately adapt to your own projects.

I have been deeply involved in the industrial electric control board industry for many years, and I often receive the consultation from equipment manufacturers: How to choose the manufacturer for the customization of high-voltage brushless fan control board?
