Abstract: An electric motor includes processing circuitry. The processing circuitry estimates the position of a rotor in a mode selected from an induced voltage mode and a harmonic superimposition mode. The induced voltage mode is a mode of estimating the position of the rotor based on an induced voltage that is generated in three-phase coils. The harmonic superimposition mode is a mode of estimating the position of the rotor by superimposing a harmonic on a command value. The processing circuitry estimates the position of the rotor using the induced voltage mode when the output voltage is greater than or equal to a predetermined threshold value and estimates the position of the rotor using the harmonic superimposition mode when the output voltage is less than the threshold value.
