Is the power consumption the same when the fan is used in different gears?
High speed gears consume more energy, but high efficiency because of large output power. Low energy consumption is slightly lower, but the efficiency is low and the heat production is serious.
The maximum design speed is used as the design value, and the minimum speed deviates from the design value.Fan blade is also a sensitive load, the power of shaft and speed are three times, and the higher the speed, the greater the energy consumption
Asynchronous motor efficiency is a very delicate thing, when the speed is similar to the design speed, the efficiency is very high, when the deviation is large, the efficiency is very low. Therefore, the speed range of the general fan is also very small
