2023-01-0635410Different principles1. The principle of the brush motor: the brush motor uses mechanical equipment to reverse, the magnetic pole does not move, and the coil rotates. When the motor is working, the coil and commutator rotate, the magnetic steel and carbon brush do not rotate, and the alternating change of coil current direction is completed by the c...
2022-11-2333600In 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...
2022-11-22367001、 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...
2022-11-2232100Servo 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...
2022-11-2217800The 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....
2022-11-1819800Ordinary 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...
2022-11-1833200All 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...
2022-11-1822000In 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 ...
2022-11-1835200Although 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...
2022-11-1832800Stepping 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...
