Abstract
An inverter control method is a method for controlling an inverter that outputs an application voltage, which is a voltage to be applied to a motor that drives a load by using rotation of a shaft. The method includes: causing the inverter to output the application voltage having an amplitude smaller than a first maximum and causing the motor to rotate at a first speed and drive the load which is predetermined; and causing the inverter to output the application voltage having an amplitude of a second maximum and causing the motor to rotate at a second speed and drive the predetermined load. The first maximum is a possible maximum value of an amplitude of the application voltage when the motor drives the predetermined load at the first speed. The first speed is a maximum of a speed of rotation of the motor when the motor drives the predetermined load. The second maximum is a possible maximum value of the amplitude of the application voltage when the motor drives the predetermined load at the second speed. The second speed is lower than the first speed.
