Review on Heat Dissipation Technology for In-wheel Motor of Electric Passenger Vehicle
摘要
Abstract
In-wheel motors represent the future driving technology for electric vehicles,offering a more efficient alternative to central motors by simplifying the mechanical transmission system.However,the issue of thermal accumulation during prolonged continuous operation can affect the performance and lifespan of in-wheel motors.Excessive temperature rise and poor heat dissipation are significant challenges that hinder in-wheel motors from becoming mainstream in the electric passenger vehicle market.By reviewing the work of domestic and international scholars on temperature measurement methods,loss models,and cooling structures for in-wheel motors,the temperature rise distribution during operation and the differences in heat dissipation capabilities among various cooling structures are comprehensively analyzed,the research methodologies and different cooling structures for in-wheel motors are summarized.关键词
