For AC motors, when the voltage is constant, the frequency of the voltage becomes higher or lower, so what is the impact on the motor?.
Induction motor, power frequency rise will make the speed increases, the rise of the motor inductance frequency increase, the current will be reduced, reducing the temperature rise of the motor current will decline.When the power supply frequency decreased, motor speed will decline, the current decline due to the increased motor inductance, the temperature should be increased.
The rise of the motor inductance frequency increases, suitable for high voltage, if the voltage at constant current is reduced; decrease of the power supply frequency of the motor inductance decreases for low voltage, current increases if the voltage is constant, and there may be magnetic saturation and heat and even burn.
Frequency will affect the motor speed, high frequency, motor speed, low frequency, motor speed is slow.
