What are the control methods of DC motors?
2022-06-29 14:05
For a long time, DC motors have good linear speed regulation characteristics, simple control functions, higher efficiency and excellent characteristics. Therefore, DC motors are widely used for speed control. Especially with the development of computers in the field of human control, and the high switching frequency, control of second-generation power semiconductor devices (GTR, GTO, MOST, IGBT, etc.), pulse width modulation (PWM) is more and more commonly used.

Speed control mechanisms are suitable for many situations, such as controlling the motion of robotic vehicles, the motion of motors in paper mills, and the motion of motors in elevators that use different types of DC motors. The DC motor control method is done manually by the worker or by using any automatic control tool. This seems to be the opposite of the speed limit, which must be the opposite of the natural change in speed because of changes in shaft load.

In the next ten years, my country's crane industry will transform into a new student
From 2010 to 2014, China's tower crane manufacturing industry experienced the fastest growth in the three years. In the three years, the number of tower crane manufacturing enterprises soared from more than 280 to nearly 600. This is mainly due to the 4.8 trillion investment effect. By 2013, with the fading of the investment effect of 4.8 trillion yuan, the growth of the whole industry of tower crane manufacturing industry declined seriously. It has become an indisputable fact that China's economic growth will continue to slow down in the next five years. This is a rare good opportunity for the country to "adjust the industrial structure and change the development mode". Similarly, the tower crane manufacturing industry is also facing adjustments. The adjustment of the tower crane manufacturing industry will present three trends: First, the industry will speed up the reshuffle, eliminating the inferior and reserving the superior; second, the modernization level of the industry's production and manufacturing will be improved, thereby improving production efficiency and product quality; third, the concentration of the industry It will continue to improve, that is, some large-scale manufacturing enterprises will emerge.
