Because general direct-drive motors are equipped with high-resolution encoders, direct-drive products can achieve a level of accuracy higher than ordinary servos. At the same time, the direct connection method is used to reduce positioning errors due to mechanical structures, thereby ensuring Higher process accuracy. All these are technically familiar to everyone, so "direct drive technology" is a new concept in a sense. From the perspective of direct-drive motors used in the field of home appliances, it can make the motor's efficiency 16 times that of traditional motors and save about 35% of energy. If it is used in drum washing machines, its energy consumption is not inferior to that of pulsator washing machines. It can solve the problems of large vibration and noise of the drum washing machine.
Direct drive technology, as a branch of drive theory, is increasingly being used in various industries. Taking a direct-drive logistics suspension conveyor system as an example, each conveyor system needs thousands of deep-slot single-phase linear induction motors. The current cost-effectiveness has reached the stage where it can be used initially. Once it is widely used, it can greatly reduce The system cost improves the competitiveness of the product; the sheet metal industry constantly puts forward higher requirements for cutting quality and cutting efficiency. Laser cutting machines driven by linear motors came into being because of their fast speed, large acceleration, and high positioning accuracy. It is favored by mid-to-high-end customers in the market; it uses a linear motor-driven workbench with a speed of 30 times that of the traditional transmission method, an acceleration of 10 times that of the traditional transmission method, and a 7-8 times increase in rigidity. To the working dead zone, the linear servo system composed of it can achieve higher frequency response.
With the further advancement of intelligent manufacturing, a new trend of linear drives replacing rotary servos has emerged in the industry 4.0 application scenario, making the development of linear drive applications faster and the market has great potential. It will also become a new application of direct drive technology in 2019. The beginning of the era.
