| description | The invention relates to an operation and maintenance method for high-efficiency operation of a motor. The method comprises: step one, a power factor is improved; to be specific, a motor with the matched power is selected when motor type selection is carried out, so that the load rate reaches over 85%; a high-quality power source is selected; a filter capacitor is added inside a frequency converter of the motor, proper electric reactors are connected in series to the input side and the output side of the frequency converter, and harmonic waves are absorbed and impedance of the power source orload is increased, wherein the high-voltage frequency converter has a good effect of improving the power factor; and a capacitor is connected in parallel with the motor and load compensation is carried out; step two, the temperature change of the motor is monitored, the operation state of the motor is predicted, and the motor can work reliably; and step three, a vibration speed effective value insteady-state operation of |
