Title:
AXIAL ELECTRIC MOTOR ROTOR, AXIAL ELECTRIC MOTOR, POWER ASSEMBLY AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/037312
Kind Code:
A1
Abstract:
The present application provides an axial electric motor rotor, an axial electric motor, a power assembly, and a vehicle. The axial electric motor rotor comprises a rotor support and a magnet structure, the rotor support comprises a first support portion and a second support portion that are arranged coaxially, the first support portion is sleeved on the side of the second support portion away from the axis of the second support portion, a plurality of magnet units in the magnet structure are sequentially arranged in a circumferential direction, each magnet unit is located between the first support portion and the second support portion, the magnet units are respectively fixed to the first support portion and the second support portion at two ends in the radial direction of the second support portion, and at least a portion of a first soft magnet and at least a portion of a first permanent magnet in the magnet units are stacked in the axial direction. In the present application, a magnet structure is formed by means of arranging a plurality of magnet units around each other, so that the processing process of each magnet unit is simpler, and fixation is realized by means of a rotor support, so that the reliability is improved; and the first soft magnet is configured to gather magnetic lines of force, thereby improving gap flux density, increasing output torque, and enhancing axial electric motor performance.
