In the past two years, IDC has continued to pay attention to the size, competitive landscape and technology ecological development of China's smart home market, witnessing the exploration process of the market from the embryonic stage to the initial outbreak stage. With the arrival of 2020, China's smart home market will enter a period of large-scale development, the upgrading of connectivity and interaction will push industrial intelligence to a wider range of products and updated application scenarios, and the industry and media changes brought about by digital transformation will create greater consumer power and demand for the smart home market.

PCBA plate making is very important, gold plating, tin plating process is also very important, below we talk about various processes. Advantages and disadvantages of various coatings: First, we have to understand why nickel plating, silver plating, tin plating, tin plating, zinc plating, gold plating. We usually use tin plating and gold plating. Common: The coatings all have a common benefit of being antiseptic (improving antioxidant capacity) and playing a decorative role. Here are the differences

Since the beginning of this year, with the explosion of various black technologies of iPhone, "wireless charging" technology has also attracted much attention from all walks of life. In fact, this black technology was pushed to the forefront of technology trends at the beginning of its launch. After a period of experience, many users have become disillusioned with this technology because it does not bring a better charging experience.

microwave oven (microwave oven), as the name suggests, is a modern cooking stove that uses microwaves to heat food. Microwave is a kind of electromagnetic wave. Microwave oven is composed of power supply, magnetron, control circuit and cooking chamber. The power supply provides about 4000 volts of high voltage to the magnetron, which continuously generates microwaves under the excitation of the power supply, and then passes through the waveguide system and is coupled to the cooking chamber. Near the inlet of the cooking chamber, there is a rotating stirrer, because the stirrer is a metal fan, which reflects the microwave in all directions after rotation, so the microwave energy can be evenly distributed in the cooking chamber, thus heating the food. The power range of microwave ovens is generally 500 to 1000 watts.

Becoming a formal embedded motherboard design and development engineer is a laborious process that requires developers to maintain and manage every bit and byte of the system. From well-regulated development cycles to rigorous execution and system inspections, there are many techniques for developing highly reliable embedded systems. Here are seven easy-to-use, long-lasting tips that can go a long way toward making your system run more reliably and catching unusual behavior.

In recent years, with the progress of drive and control technology, the home appliance industry has ushered in the spring of development, and energy saving, environmental protection and intelligence have become a new development trend. With the emergence of energy efficiency standards for high-power home appliances such as air conditioners, range hoods, and refrigerators, the field of home appliances will face a new round of energy efficiency changes. In addition, with the deepening of the national advocacy of energy conservation and emission reduction, the field of industrial control has also put forward higher and higher requirements for motor energy efficiency. With the original motor drive control technology to promote the energy efficiency in the field of home and industrial control, to bring the ultimate experience to people's lives, is the original intention of the establishment of Yingfei and has always adhered to the belief.

In order to strengthen the professional knowledge and ability of R & D personnel, further improve work efficiency to adapt to the development of today's motor technology, so that the overall ability of employees to maintain a long-term dynamic advantage. On March 26, 2019, Infell Electronics held a training lecture on the Design of Permanent Magnet DC Motors. Professor Huang Daxu, former Director of West Micro Institute, delivered the lecture. All the staff of R&D department, some employees of purchasing and sales participated.

With the progress of society and the rapid development of science and technology, people's living standards are getting higher and higher, the vacuum cleaner has gradually penetrated into people's lives, for the vacuum cleaner, its interior has an important part, that is, the vacuum cleaner motor. There are many kinds of vacuum cleaner motors on the market, and consumers should do what when choosing?

The problem comes down to the distinction between PMSM and BLDC. The difference between the two, which I've said before in this column, is simple.

Dc brushless motor is composed of main body and driver, which is a typical mechatronics. The stator winding of the motor is mostly made of three-phase symmetrical star connection, which is very similar to the three-phase asynchronous motor. Here's how it works.
