Title:
RING-SLOT CURRENT COLLECTOR HOMOPOLAR ELECTROMAGNETIC TRANSMISSION AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/236440
Kind Code:
A1
Abstract:
A ring-slot current collector homopolar electromagnetic transmission (HET) is a continuously variable transmission. Each rotor has at least one magnetically conductive conductor. A stator has at least one DC excitation coil, and has a coolant passage. At least two main magnetic circuits pass through the magnetically conductive conductor. There is a main circuit passing through the magnetically conductive conductor and a liquid metal gap between the rotor and the stator. The radius of the gap is smaller than the maximum radius of the rotor, and is in an inverted "U" shape. Moreover, two connected circulation gaps implement self-circulation flow. The electromagnetic properties thereof are adjusted by means of changing excitation current. The present invention solves the problems of the insufficient functions, low performance and high costs of existing mechanical continuously variable transmissions, fluid torque converters and AC variable frequency speed regulation transmission systems, and avoids problems caused by existing HETs using liquid metal full flow circulation to the outside for heat dissipation. HET applications comprise fully and efficiently utilizing vehicle power, wind power generation, grid peak regulation, engine fuel energy, wind energy, grid power, flywheel energy storage, and vehicle kinetic energy.
