- 2024-12-03The difference between shunt excitation and separate of DC m
A DC motor is a motor that converts DC electrical energy into mechanical energy. According to the different excitation methods, DC motors can be divided into two categories: separately excited DC motors and shunt-excited DC motors. ...
- 2024-12-02Discuss the causes of AC motor running at low speed
Power supply problem can be one of the main reasons for AC motor running at low speed. If the power supply voltage is lower than the rated voltage of the motor, the motor will not work properly. If the power supply voltage is unstable or the ...
- 2024-11-29Motor temperature requirements and related precautions
A single-phase motor coil is a coil wound by wire. It is one of the main components of the motor and is mainly composed of a coil body, an insulation layer and a connecting wire. Coil body: A coil wound by wire, which directly participates ...

Russian explosion-proof certification (implementation regulation TR CU 012/2011, the mark is EAC-EX) is one of the mandatory documents, which gives the right to work with certain types of industrial equipment and equipment, and its name is u ...
- 2024-11-26Causes and treatment methods of motor smoke
Many people will feel very worried after the motor starts smoking, worrying whether the motor has burned out. In fact, the motor smoking does not mean that it has burned out. After the motor starts smoking, we need to first determine whether ...
- 2024-11-25How is the axial force of a three-phase AC motor formed?
Whether it is a high-voltage or low-voltage motor, customers often report shaft drift problems or bearing temperature rise problems due to axial force. The best working state of a motor is to ensure an ideal relationship between the motor an ...
- 2024-11-22Starting method of three-phase asynchronous motor
The direct starting method is the simplest and most commonly used starting method. Its principle is to directly connect the three-phase power supply to the three windings of the motor to start the motor. ...
- 2024-11-21Analysis of the causes of three-phase AC motor burnout
Analysis of the causes of three-phase AC motor burnout, the causes of three-phase AC motor burnout can be divided into load, power supply, motor insulation, and phase loss. ...
- 2024-11-20Analysis of the mean trouble-free working time of motors
In the field of industrial production and power drive, motors are core equipment components, and their reliability is crucial. One of the key indicators for measuring motor reliability is the mean time between failures (MTBF). Understanding ...
