The cause of the brushless dc motor temperature is too high: 1, the power supply voltage is high, more than motor more than 10% of the rated voltage, the motor iron loss caused by increased, make motor fever. 2, power supply voltage is too low, below the motor more than 5% of the rated voltage, the motor at rated load operation will fever. Solution is to adjust the grade of the transformer tap-changer, adjust the supply voltage to the normal range. 3, unbalanced three-phase power supply voltage, and voltage imbalance degree is more than 5%, cause unbalanced three phase current and make the motor heating. 4., lack of phase operation. 5, the load is too big, should reduce capacity suitable motor load or replaced 6, start, too often. A fault 7, the mechanical load
