Document Type and Number:
WIPO Patent Application WO/2022/264407
Kind Code:
A1
Abstract:
An electric motor of the present invention comprises a stator, a rotor, and a built-in board (11) that supplies current to the stator. The built-in board (11) has a high-voltage circuit (71) connected to a high-voltage power supply (77), and a low-voltage circuit (72) connected to a low-voltage power supply (78). An inverter that converts inputted DC voltage to AC voltage and supplies the result to the stator is included in the high-voltage circuit (71), and a control unit that controls the inverter is included in the low-voltage circuit (72). An inductor (73A) is arranged in the low-voltage power supply line that is the line connecting the low-voltage power supply (78) and the low-voltage circuit (72).
