The difference between variable frequency motor and ordinary motor

DIFFERENCE

Ordinary motor internal cooling fan and fan movement with the same line, and frequency conversion motor these two are separate. Therefore, when the frequency conversion of the ordinary fan is too low, it may be burned off due to overheating; Frequency conversion motor due to the high frequency magnetic field, so the insulation level is higher than the ordinary motor, strengthen the groove insulation: the insulation material strengthens and increases the thickness of the groove insulation to improve the level of withstand high frequency voltage.

The operating point of the ordinary motor is basically at the inflection point of magnetic saturation. If it is used as frequency conversion, it is easy to saturate and produce a high excitation current. While the frequency conversion motor increases the electromagnetic load when designing, making the magnetic circuit not easy to saturate. In addition, variable frequency motors are generally divided into constant torque special motors, special motors with velocity measurement devices and medium frequency motors with feedback vector control.
