2022-11-1860600Laser cutting machines are generally divided into metal laser cutting machines and non-metal laser cutting machines. Non metal laser cutting machines mostly use CO2 lasers as generators, while metal laser cutting machines use fiber lasers as generators. Both types of cutting machines play an important role in industrial production, greatly improvin...
2022-11-1857500What are the characteristics of industrial chillersIn industrial production, the operation of the machine can not avoid the generation of heat. The industrial chiller is an indispensable cooling equipment. The industrial chiller generally has the following three characteristics.1、 Stable operation and strong performanceThe industrial chill...
2022-11-1859800The five most commonly used methods for frequency converter to control motor are as follows:The low-voltage universal frequency conversion output voltage is 380~650V, the output power is 0.75~400kW, and the working frequency is 0~400Hz. Its main circuit adopts AC-DC-AC circuit. Its control mode has experienced the following four generations....
2022-11-1851400Ordinary asynchronous motors are designed according to the principle of constant frequency and constant voltage, which cannot fully meet the requirements of variable frequency speed regulation. The influence of frequency converter on motor is as follows:1. Motor efficiency and temperature riseNo matter what form of frequency converter, it will ge...
2022-11-1864500All motors have a fixed operating power, which is called rated power, and the unit is watt (W). If the actual power of the motor exceeds the rated power of the motor under certain circumstances, this phenomenon is called motor overload. Overload can easily lead to motor overheating, resulting in reduced winding insulation, and ultimately motor burn...
2022-11-1859800In addition to energy conservation, intelligent motor control technology is also one of the key directions of future development. Generally speaking, the intellectualization of motor control can be realized from two aspects.First, expand the sensing range, that is, add more sensors in the motor control scheme, such as vibration sensors, to ...
2022-11-1869100Although motor control technology and circuit will vary according to different types of motors and different application requirements, the ultimate purpose is to operate the motor manually or automatically, such as start stop, advance reverse, speed, twist, and voltage overload protection. That is to say, motor control needs the support of electron...
2022-11-1861100Stepping motor is a kind of induction motor. Its working principle is to use electronic circuit to change the DC current into power supply. The current is controlled by multi-phase sequence. Only when this current is used to supply power to the stepping motor can the stepping motor work normally. The driver is a multi-phase sequence controller that...
