The so-called silicon controlled rectifier, in fact, is a kind of power control electric appliance based on power electronic power devices and intelligent digital control circuit as the core. The DC power supply of this dragging device uses the DC voltage of the thyristor rectifier to supply power to the hoisting motor. The armature and magnetic field of the motor can be powered by the thyristor rectifier, because the DC voltage of the rectifier can be adjusted uniformly through the trigger delay angle, and the speed of the motor can be uniformly changed to achieve stepless speed regulation.
It is characterized by power saving, and there are many other advantages such as high efficiency, no mechanical noise and wear, fast response speed, small size, light weight, etc. It is the first choice and necessary power product for manufacturers in the production process.
