Different types of speed regulation

1.Voltage speed regulation: By changing the input voltage to adjust the fan speed, mainly used in DC cooling fans. Although the cost is low, the accuracy and stability are slightly lower than that of current speed regulation.

2.PWM speed regulation: The use of pulse width modulation (PWM) signal to change the working period of the motor is currently the most widely used method, taking into account efficiency and accurate control.

3.Mechanical speed regulation: Adjust the speed by changing the fan blade Angle or installing different gears, which is more common in industrial heat dissipation equipment, but the adjustment process is more complicated.

4. Current speed control: Current speed control is a way to change the fan speed by adjusting the input current. It is usually used in DC cooling fans.

Practical application case analysis

Industrial heat dissipation device: For devices in high temperature environments, it is recommended to select the current adjustable speed fan, such as the axial cooling fan 110v, which can maintain stable performance under complex loads.

Household cooler fan: Choose the products provided by high quality cooler axial fan ac 220v manufacturer, which are both efficient and economical, suitable for scenarios requiring long-term stable operation.

Wholesale market demand: For customers who need to purchase in bulk, the axial flow fan wholesale price is more attractive, and it is also flexible to choose different speed regulation schemes to meet special needs
