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...
2022-11-1837900The 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....
2022-11-1830600Ordinary 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...
2022-11-1843600All 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...
2022-11-1833400In 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 ...
2022-11-1845700Although 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...
2022-11-1842400Stepping 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...

Steering boxThe steering box, also known as commutator and steering gear, is a power transmission mechanism and a series of reducers, which are widely used in the industrial field.The steering box has single axle, double horizontal axle and single vertical axle, and double vertical axle can be selected. Speed ratios 1:1, 1.5:1, 2:1, 2.5:1, 3:1, ...
2022-11-1732401There are many kinds of reducers with different models, and different types have different purposes:According to the transmission type, it can be divided into gear reducer, worm reducer and planetary gear reducer;According to different transmission stages, it can be divided into single-stage and multi-stage reducers;According to the gear shape, it ...
2022-11-1744400It is believed that everyone is familiar with the harmonic reducer. The harmonic reducer is a kind of machinery, which matches the speed between the prime mover and the working machine or the actuator, and transmits the torque. Robot joint reducer is a power transmission mechanism. It uses the speed converter of the gear to reduce the number of mot...
