Document Type and Number:
WIPO Patent Application WO/2021/179435
Kind Code:
A1
Abstract:
Disclosed is a brushless electric motor. The brushless electric motor comprises a stator assembly and a rotor assembly, which are coaxially sleeved. The rotor assembly comprises a rotary shaft and a rotor yoke, which is coaxially sleeved with the rotary shaft, at least two magnetic steel accommodating grooves for accommodating magnetic steel are provided in an inner wall of the rotor yoke along the circumference thereof, magnetic steel is inserted into the magnetic steel accommodating grooves, and a magnetism-isolating gap is provided between the at least two magnetic steel accommodating grooves. By means of the external design of a rotor, the size and weight of the electric motor are effectively reduced, and under a condition of the same power, the working efficiency of the electric motor is effectively improved, such that the endurance of a lithium battery can be further improved, an energy saving requirement is met, and the user experience is better.
