The invention relates to the field of motor design, and in particular relates to a high-power-density axial magnetic field permanent magnet motor structure which comprises two rotors, a stator and a casing. The stator comprises a stator iron core module, an armature winding, a stator end cover, a stator sleeve, a stator cooling pipe and a water segregator, and the stator end cover and the stator sleeve are installed at the two side ends of the stator iron core module respectively. Each rotor comprises a rotor iron core and a rotor permanent magnet, a cup-shaped rotor supporting disc is embedded in the outer ends of the rotor iron core and the rotor permanent magnet, and a rotating shaft is arranged among the rotor iron core, the rotor permanent magnet and the rotor supporting disc. The casing comprises a wiring terminal and a water inlet and outlet which are arranged at the end of the casing body, and the water inlet and outlet is communicated with a casing cooling pipeline arranged in the casing. By adopting the combined cooling mode of the double-rotor segmented modular yoke-free stator iron core, the stator and the casing, the length of a stator and rotor magnetic flux path can be effectively shortened, the iron core loss is reduced, the motor mass is reduced, and the motor efficiency and the power density are improved.
Description
technical field [0001] The invention relates to the field of motor design, in particular to a high power density axial magnetic field permanent magnet motor structure. Background technique [0002] Compared with conventional radial field motors, axial field permanent magnet motors have the characteristics of short axial length, large torque and high power density, and are widely used in new energy vehicles, wind power generation, elevator traction, etc. The traditional single-rotor single-stator axial field permanent magnet motor usually has a large unilateral magnetic pull. In order to overcome the unilateral magnetic pull, the axial field permanent magnet motor is usually designed as a bilateral structure, that is, a double-stator intermediate-rotor structure or a double-rotor intermediate-stator structure. The stator can be divided into slotted, yokeless, ironless and other forms. Among them, the double-rotor single-stator stator yokeless structure has received extensiv...
