Answer：During the manufacturing and assembly process of the motor, the insulation damage of the winding often causes the coil short circuit or open circuit fault. The winding is the core part of the motor. Aging, moisture, heat, erosion, foreign matter intr...
Answer：The life of a three-phase asynchronous motor depends mainly on the electrical, magnetic, thermal, vibration, environmental conditions and maintenance to which the motor is subjected during use. Usually, a motor can work for 15,000 to 80,000 hours und...
Answer：The nameplate of the motor product specifies several important parameters such as the rated power, rated voltage, rated current and rated frequency of the motor. Among the several rated parameters, the rated power is the basic parameter with the rate...
Answer：When a motor fails to operate properly, to repair it, it must be checked in a certain procedure, that is, several tests must be done systematically to find the root cause of the fault. After these tests, it is determined whether the motor only needs ...
Answer：Rated power and rated torque are performance parameters that should not be exceeded during the application of the motor. Overload operation is also very likely to cause the motor's mechanical properties to collapse. Of course, non-conforming pro...
Answer：Compared with wound rotor motors, cast aluminum rotor motors have better safety performance, and the theoretical electrical failure rate is half of that of wound rotor motors. However, some motors with special working conditions and specific uses are...
Answer：Vacuum cleaners are an indispensable part of our daily life. With the development of smart home appliances, the improvement of vacuum cleaners has also been put on the agenda. Recently, we have received many inquiries about the application of brushle...
Answer：Simply put, a brushless motor controller is a control device that can be used to provide a closed-loop commutation control signal for a three-phase brushless motor . It mainly includes three parts: a power conversion circuit, a microcontroller (singl...
Answer：Electromagnetic sound is a kind of noise that often occurs in motor products. High-frequency electromagnetic sound is sharp and relatively harsh, similar to a whistle; low-frequency electromagnetic sound is relatively dull, similar to the sound of a ...
Answer：A sorting machine is a high-end financial equipment, a financial machine specially used for counting and sorting coins or banknotes. It is generally divided into two types: coin sorting machines and banknote sorting machines. The banknote sorting mac...
