Seeking help with mechanical pumps
Thread Content
I need help – what is the purpose of the small motor attached to the back of this motor? I need a detailed solution.
It is recommended to look for the instructions according to the label, or check the equipment operation manual; they should be available for reference.
This is the first time I’ve seen this; looking forward to an answer
It seems to be a fan used for cooling variable-frequency motors; I’ve seen one like this for the first time.
This is an inverter-driven motor, and behind it is the cooling fan.
Variable-frequency motors have different speeds depending on the frequency, which makes it impossible for them to meet the cooling requirements of fans; therefore, a separate fan motor is used.
It appears to be a fan that operates independently; in other words, even after the main motor stops, the fan continues to spin and provide cooling.
The separate fan located behind the variable-frequency motor is used for cooling the main motor
