  • ROTOR, MOTOR, AND VEHICLE
    Publication number: 20240146126
    Abstract: Example rotors, motors, and vehicles are described. One example rotor includes a central core and a plurality of peripheral cores. Each peripheral core is spaced apart from the central core to form a first separation gap, a second separation gap, and a third separation gap that communicate with each other. The first separation gap and the second separation gap are respectively configured to accommodate a first permanent magnet and a second permanent magnet. The first permanent magnet and the second permanent magnet are respectively spaced apart from the sleeve to form a first magnetic isolation gap and a second magnetic isolation gap. Each peripheral core is provided with an open slot for accommodating a third permanent magnet and a fourth permanent magnet.
