Answer：The objective existence of teeth and slots in the stator and rotor cores of the motor, the non-orthodox waves in the spatial distribution of the winding magnetic potential, and the uneven saturation degree of the magnetic circuit system all lead to t...
Answer：Slip is a unique performance of asynchronous motors, that is, the motor speed is always lower than the speed of the motor's rotating magnet. Motor starting, no-load and load operation represent different operating states of the motor respectivel...
Answer：During the motor test, some performance parameters of the motor are measured and evaluated through the current and loss under different voltage conditions when the rotor is blocked. This is a manual operation process. During the operation of the moto...
Answer：The power factor is an important performance indicator of the motor. The power factor of an asynchronous motor is a measure of the proportion of the active power actually consumed in the apparent power input of the asynchronous motor. Its value is th...
Answer：Regarding the topic of improving the efficiency of the motor itself, how much energy can be saved for every ? This is a question that everyone is very concerned about. But how to compare and analyze the efficiency improvement and energy saving effect...
Answer：In the process of matching the motor and the inverter, the capacity selection of the inverter is crucial. If the inverter capacity is too small, the motor will not be able to start. On the contrary, if the inverter capacity is too large, it will not ...
Answer：The rotating shaft is a very critical structural component of motor products and is the direct subject of mechanical energy transmission. At the same time, for most motor products, the rotating shaft will also serve as an important component of the m...
Answer：For small and medium-sized motors, there are two most common shaft extensions, namely cylindrical and conical. A careful observation reveals that motors used in lifting and metallurgy generally use conical shaft extensions, while most other load moto...
Answer：Phase loss is an electrical fault unique to three-phase motors. It may occur during the test phase of the motor or during the use phase of the motor. It may be a problem with the manufacturing quality of the motor or a problem with the use of the mot...
Answer：Compared with other mechanical equipment, motor products involve multiple engineering parameters such as mechanical, electrical and wind circuits, and are relatively complex mechanical products. From the perspective of the mechanical performance of t...
