In everyone's impression, the air conditioner always needs a lot of power, because the air conditioner motor needs a lot of power to run. Therefore, for a long time, the upgrading direction of air conditioning lies in the research of air conditioning motor. "DC" has become an important direction for upgrading the product structure of air conditioni...

Cause of failure① Wiring error;② Electromagnetic interference;③ Encoder hardware damage caused by mechanical vibration;④ Pollution caused by the site environment;2. Troubleshooting① Check the wiring and eliminate errors;② Check whether the shielding is in place, check whether the wiring is reasonable and solve it, and add filt...
2022-11-22370001、 Torque controlThe torque control method is to set the external output torque of the motor shaft through the input of external analog quantity or the assignment of direct address. For example, if 10V corresponds to 5Nm, when the external analog quantity is set to 5V, the motor shaft output is 2.5Nm: if the motor shaft load is lower than 2.5Nm, th...
2022-11-2232300Servo motors are mainly divided into AC servo and DC servo.The basic structure of AC servo motor is similar to that of AC induction motor (asynchronous motor). There are two excitation windings Wf and control windings WcoWf with phase space displacement of 90 ° on the stator, which are connected to a constant AC voltage. The purpose of controll...
2022-11-2218200The 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....
2022-11-1820100Ordinary 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...
2022-11-1833600All 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...
2022-11-1822300In 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 ...
2022-11-1835500Although 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...
2022-11-1833100Stepping 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...
2022-11-1827400"The cleaning of industrial parts is widely acknowledged as a key value-adding step in the overall production chain. But new trends – such as Industry 4.0, miniaturization, electromobility, vehicle lightweight design and new or modified manufacturing and coating technologies – pose new challenges for cleaning industrial parts and surfaces.The story...
2021-09-1619250"hi all was using my cnc today cutting well. then all of a sudden compressor burns out its motor which blows main fuse cnc crashes now when i re started it will not moveanyone had same problems if so how do you fix cheers"
2021-09-2920700"Hi,I am new to this and I have run into a problem with touch probing after I have grounded my table to the ground pin.My setup is that I have a power connection to the machine torch tip, and from a wire clamped to the cutting plate going to an input in the software.This results in input activating when machine torch tip touches the cutting plate. ...
2021-09-2917400"The dm4400m that I am retrofitting has a spindle motor that I’d like to salvage if possible.It appears to be a DC servo drive motor180vdc with 11nm stall torque per the label.It says it’s a model MT 40ZD4-45 motorAny suggestions on a drive to run this motor"
