The power supply voltage is high, the excitation current is increased, and the Taichung motor will distribute heat. Excessive high voltage will insulate the insulation of the Taicheng motor, which may cause it to be broken down. When the power supply voltage is too low, the electromagnetic torque will be greatly reduced. If the load torque is not reduced, the rotor rotation number is too low. At this time, the slip rate is increased, causing the Taicheng motor to be overloaded and heated, which will affect the Taicheng motor for a long time. Life expectancy. When the three-phase voltage is asymmetrical, that is, when the voltage of one phase is high or low, it will cause the current of a certain phase to be too large, and the motor of Taichung will generate heat. At the same time, the torque will be “one bang”, and the winding will damage the winding. . In short, whether the voltage is too high or too low or the three-phase voltage is asymmetrical, the current will increase, and the Taichung motor will heat up and damage the Taichuang motor. Therefore, according to the national standard, the power supply voltage of the motor is changed within ±5% of the rated value, and the output power of the Tektronix motor is maintained at the rated value. The power supply voltage of the Tektronix motor shall not exceed ±10% of the rated value; the difference between the three-phase power supply voltage shall not exceed ±5% of the rated value.
