The operation of the axial fan is driven by the motor. In fact, any equipment is the same. If you want to run, you must have a similar "engine". When choosing the motor of the axial flow fan, it is always hoped that the motor can drive the impeller to reach the rated speed quickly and work normally. The starting of the motor includes the whole process of power-on starting and acceleration. The starting methods are divided into full pressure starting and decompression starting.
Reasonable selection of the starting method of the motor must be based on factors such as the capacity of the power supply grid, the requirements of the mechanical load on the starting torque, and the characteristics of the motor itself, and a specific analysis to obtain the specified starting time. For example, the capacity of the power grid is very large, and the starting current of the motor will not cause a significant voltage drop on the power grid. In addition, the control circuit and equipment of the power grid allow a sufficient starting current to pass through in a short time, and full voltage starting can be used; if the fan When the torque required for starting is not large, and the capacity of the power grid is not very large compared to the motor, the main consideration is how to reduce the starting current and use decompression starting.
