Can you use a transducer to control the general motors? Recently, the factory has to renovate two 150 kw electric motors, which were previously controlled by the star delta, and now change the frequency converter, the electric motor is near the stove, the ambient temperature is higher. Please give me your opinion, thank you
Ordinary motor can be controlled by frequency converter, don't make the motor work in low frequency zone, the electric motor works in low frequency area electric opportunity heat.
First introduce the frequency conversion motor: look from the appearance, the most obvious is characterized by frequency conversion motor have a single cooling fan, and a cooling fan has a special connection box. The cooling fan needs to be connected to the power supply alone, so that no matter how often the motor works, it will not affect the heat dissipation of the motor. Second, the frequency conversion machine manufactured by the regular manufacturer will be adjusted internally, and it will also strengthen insulation. If there is a problem with ordinary asynchronous motor, it should be analyzed according to the situation. For example, the motor is working in low-frequency areas, and the motor may be damaged by heat dissipation. If the motor is working in the medium-high frequency area, the ordinary motor can also use the frequency converter. Also, it is the insulation problem of ordinary electric motor, the proposal is to install output reactor. Of course, it's not necessary.
If you don't reload frequently, not reload, you don't have to work long hours at low frequencies, and you have a fan that's basically ok.
