System was designed in motor selection will leave a margin on the speed of the motor where the fan is fixed cheapest, but in actual use, sometimes you want to run at a lower or higher speed, frequency transformation is therefore very necessary a. Drive motor soft start can achieve by changing the frequency of the input voltage equipment to achieve the purpose of energy-saving speed, and give the device to provide overcurrent, overvoltage, overload protection.
