How to calculate the moment of inertia of fan impeller?
The moment of inertia mainly refers to the power of the hub during the rotation of the blade. Therefore, the moment of inertia is only concerned with the design of the blade itself and the magnitude of the wind force.First, it is directly proportional to the size of the wind, and second is proportional to the windward area of the blade surface; third is proportional to the maximum power utilization factor Cp of the blade
The moment of inertia of a cylinder (the moment of inertia of a gear, a coupling, a lead screw, a shaft)J=MD^2/8
The size of the wind will not be mentioned, the Cp value of the blade, that is, the coefficient of power utilization, and the blade surface design (this coefficient has a theoretical limit, the current can do is 0.498).
