Abstract (en)

[origin: WO2022237923A1] A brushless DC electric motor for supplying multiphase supply voltage is composed of at least one rotor (2) fitted with permanent magnets (7). Number of rotors (2) ideally corresponds to the number of phases of the supply voltage. The rotors (2) are mounted on a shaft (1). The motor is composed of a split stator (3) with slots (5) to support the coils (8) of the stator windings. Each part of the stator (3) is electrically connected to the inverter to supply only one of the phases of the supply voltage, and at the same time the parts of the stator (3) are arranged relative to each other so that at least two parts of the stator (3) have a non-zero angular displacement of the slots (5) relative to each other.
