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.

Speaking of silicone products, what would you think of? Common silicone products in daily life include silicone kitchenware, remote control silicone keys and mobile phone protective cases. In fact, silica gel products have several uses in other places; For example, a beverage brand in Japan recently took the silicone lips of a actress as a gift to thank the drinkers for their support. Its name is: let you "kiss Fangze" with a well-known photo actress! Silicone false lips are set at the mouth of the beverage bottle. Every sip is like "playing kiss" with each other. It may be because the soft texture of silicone lips always gives people a secret or fragrant feeling. In fact, silica gel products are more and more widely used in market commodities. Because silica gel is insoluble in water and any solvent, non-toxic and tasteless, stable chemical properties, high adsorption performance and good thermal stability, it is the most suitable for tableware and kitchenware. The characteristics of non-toxic, tasteless, soft and moist have changed its public image - most can be made into silica gel out or silica gel daily life products, making people feel that it is close to "virtuous".

From now to the end of the 13th five year plan, the length of UHV construction lines and transformation (commutation) capacity of State Grid Corporation of China have reached 89000 km and 780 million KVA (kw) respectively. High intensity and large-scale power grid construction will run through the whole "13th five year plan" period.
