Abstract: A motor, a charging apparatus and a powertrain. The motor of the charging apparatus includes a rotor, a stator, a primary coil, and a secondary coil. The stator includes a stator core. The primary coil is wound around a yoke part of the stator core, and the primary coil is coupled to an external power supply. The secondary coil is wound around the yoke part of the stator core, and the secondary coil and the primary coil are wound around different groove structures inside the stator core. The primary coil and the secondary coil implement coupling voltage transformation through the stator core, to step up or step down an output voltage of the external power supply.
