Influence of Voltage Fluctuation on Motor
According to national standards, the motor power supply voltage changes within ± 5% of the rated value, and the motor output power remains at the rated value. The power supply voltage of the motor shall not exceed ± 10% of the rated value. The power supply voltage is high, the excitation current increases, and the motor will generate excessive heat, which will endanger the insulation of the motor and cause it to be in danger of breakdown. When the power supply voltage is too low, the electromagnetic torque will be greatly reduced. If the load torque is not reduced and the rotor speed is too low, the increase in the slip rate will cause the motor to overload and generate heat, which will affect the life of the motor for a long time.
In short, whether the voltage is too high or too low, the current will increase, the motor will heat up and damage the motor. For the permanent magnet direct drive motor system, its dedicated frequency converter has perfect protection functions such as undervoltage, overvoltage, and overcurrent, so as to avoid the impact of grid voltage problems on the life of the motor.
