Is it possible to use a motor inverter for a normal motor?
A: This kind of approach is definitely not advisable. If careful people will find that the cooling fan of the variable frequency motor is a small axial fan that is independent, the heat dissipation of the power frequency motor is to install an impeller on the main shaft. If the frequency conversion motor is used in frequency conversion, this is a very serious problem. When the motor runs at low frequency, the motor speed is very low, and at this time, the heat generated by the motor itself is the largest. If it is a power frequency motor, the ventilation air volume is instead. It becomes smaller, which causes the fan to heat up insufficiently to cause the motor to overheat.
On the other hand, the insulation level of the motor itself is very different. The inverter is both a favorite and a headache. First, it can make the motor start with no inrush current, and it can realize the output of the stepless adjustment motor to save energy. purpose. However, the inverter also brings a problem that is harmonic. If the harmonic frequency is consistent with the natural frequency of the motor itself, electromagnetic resonance will occur, which will make the sound of the motor operation abnormally large, and seriously damage the motor. .
