Title:
FRICTION-ELECTROMAGNETIC COMPOSITE POWER GENERATION DEVICE AND PERFORMANCE TEST PLATFORM AND METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/077586
Kind Code:
A1
Abstract:
A friction-electromagnetic composite power generation device and a performance test platform and method therefor. The device comprises a rotor portion (100), stator portions (200), and a central shaft (300), the rotor portion (100) and the stator portions (200) are sleeved on the central shaft (300), and two sides of the rotor portion (100) in the axial direction are each provided with a stator portion (200) in a sleeving manner; the rotor portion (100) is provided with a rotor plate (110), a magnet array (120), and blade arrays (130), the magnet array (120) is fixed on the rotor plate (110), two axial ends of the rotor plate (110) are each fixedly connected to a blade array (130), and each blade array (130) is provided with a first dielectric thin film; each stator portion (200) is provided with a stator plate (210), a coil array (220), an electrode array (230), and a friction layer (240), the coil array (220) is fixed on the stator plate (210), the electrode array (230) is fixedly connected to the inner axial surface of the stator plate (210), and the friction layer (240) consisting of a second dielectric thin film covers the electrode array (230); each friction layer (240) is in contact with the first dielectric thin film on the corresponding blade array (130), and there is an electrode sequence difference between the first dielectric thin film and the second dielectric thin film. The device improves energy conversion efficiency of power generation.
