The driver is a controller used to control the motor. Generally, the motor is controlled by position, speed and torque to achieve high-precision system positioning. Motor driver is widely used in industrial robots, NC machining and other automation equipment. It is an important part of modern operation control.

The two-component heat conductive potting adhesive can also be called AB heat conductive potting adhesive. Before curing, the heat conductive potting adhesive is liquid and has certain fluidity. It can flow into each gap for potting. After curing, an elastic adhesive layer is formed to give play to the effects of heat insulation, dust prevention and corrosion prevention, and resist high and low temperatures. Like ordinary adhesives, they will soften at temperatures above 100 ° and harden at low temperatures, but good thermal conductive adhesives can work for a long time at 150 ° ~ 200 ° without softening or fracture.

What we don't know is that the reason why the LED can work normally is closely related to the constant current provided by the driver itself in addition to heat dissipation. At present, the efficiency and power factor of most drivers are not particularly high. In detail, the driver is also a heat source. The temperature sensitivity of the components used in the driver is an important reference index affecting the operation of the driver. Therefore, in addition to the stable and reliable performance, our engineers also need to consider the upper limit working temperature and heat conduction and heat dissipation.

Motor is an indispensable part of the electrical field, and its main responsibility is to provide power. However, in the process of use, many times the motor will be heated and hot. The heating → heat transfer → cooling in the process of motor operation directly affects important indicators such as work efficiency, service life and reliability. Now it has become an urgent heat dissipation problem to be solved in the development of modern motor technology.

At present, one of the common heat dissipation methods of most compact electronic products is to use heat dissipation module to dissipate heat. What is a cooling module? In short, it is a heat dissipation channel composed of a radiator and a heat conducting material, and sometimes includes a heat dissipation fan. In the heat dissipation module, heat conducting silica gel sheet and other similar products are mostly used to assist heat dissipation, so as to achieve better heat dissipation effect.

Many LED displays with advantages are applied in the market, and there are conspicuous LED products everywhere in the city. As we all know, LED display screen is afraid of heat and water. Heat has a fatal impact on the performance of LED display screen, which directly affects the stability of display screen use process and the service life of display screen. Therefore, in order to reduce the impact of heat on LED display screen, we need to know the heat dissipation characteristics of display screen, and then make a reasonable heat dissipation design scheme for display screen.
