Meet.The adjusting method of the motor operation frequency of the present embodiment is defined the adjustment amplitude of motor input voltage, to motor
Input voltage carry out fine adjustments, the running frequency of motor can either be made to avoid its intrinsic frequency, covibration is avoided to generate,
The normal work needs of motor can be met again.
It should be noted that the mode that input voltage is adjusted in above-mentioned specific embodiment is only to enumerate, and not to this hair
Bright restriction.By repeatedly reducing the running frequency of input voltage regulation motor in above-described embodiment, the intrinsic frequency of motor is avoided
Rate.In some other embodiment, it can also afterwards reduce by repeatedly increasing input voltage, first increasing, first reduce and increase afterwards
Various ways adjust input voltage.Because if motor initially resonates, as long as input voltage changes, therewith motor turn
Speed, running frequency all change, and running frequency changes, it will be able to avoid motor intrinsic frequency, avoid resonating.
The adjusting method of the motor operation frequency of the present embodiment, input voltage and then secondary detection electricity in adjustment motor
The vibration velocity of machine, and when the vibration velocity of motor is still greater than pre-set velocity, the input voltage of motor, Ke Yijin are adjusted again
One step ensures that the running frequency of motor avoids its intrinsic frequency, and can by the way that input voltage is raised and lowered predeterminated voltage,
Change the rotating speed of motor, and then the running frequency of regulation motor, entire detection and adjusting process are automatically performed, and are greatly reduced
The complete machine oscillation of motor effectively extends the service life of motor.
