WIPO Patent Application WO/2024/082798
Kind Code:
A1
Abstract:
Disclosed in the present application are an electric motor and the use thereof. The electric motor comprises a rotor (100) and a stator (200) enclosing the rotor (100). The rotor (100) comprises an iron core (110) and permanent magnets (120) arranged on the iron core (110); the width of an air gap of the electric motor is δ, and the number of magnetic poles in the rotor (100) is 2 P; the permanent magnet (120) contains x % (mass percent) of cerium, and the value of x ranges from 3 to 10; the thickness of the permanent magnets (120) is h, and the sum of the widths of the permanent magnets (120) in each magnetic pole is w, wherein x ≤ 23 * h - 25, 1 + δ ≤ h ≤ 1.4 + δ, and 2.5 * x + 15 ≤ 2P * h * w/5 ≤ 4 * x + 37; and all the units of h, w and δ are mm.
