Title:
ELECTRIC MOTOR BASED ON DOUBLE-LAYER ROTOR STRUCTURE, AND DOUBLE-LAYER ENERGY STORAGE FLYWHEEL
Document Type and Number:
WIPO Patent Application WO/2020/118819
Kind Code:
A1
Abstract:
Disclosed are an electric motor based on a double-layer rotor structure, and a double-layer energy storage flywheel. The electric motor comprises a mounting shell (10), a stator, an inner rotor (30), and an outer rotor (40). The electric motor can be applied to the double-layer energy storage flywheel, and can also be used as a pure electromotor, a pure power generator or an integrated electromotor and power generation machine, namely, one of the inner rotor and the outer rotor serves as an electromotor, and the other serves as a power generator. The electric motor can be either an electric motor without an iron core or an electric motor with an iron core, and is preferably an electric motor without an iron core. According to the present application, the inner rotor (30) is not physically connected to the outer rotor (40), and the inner rotor (30) and the outer rotor (40) are coupled through the action of a magnetic field, such that the inner rotor (30) and the outer rotor (40) are in linkage with each other.
