1、电动汽车驱动方式与驱动电机研究摘要随着中国日益严重的大气污染和石油资源的愈加紧缺，发展电动汽车已经成为国家战略。国内众多大学、研究所和汽车企业纷纷投入巨大精力参与电动汽车研发，目前已取得多项突破。相较于传统内燃机汽车，轮毂电机驱动型电动汽车拥有无可比拟的优势：大大简化的机械传动机构、优秀的传动效率、多样的驱动方式等。本文顺应潮流，以轮毂电机驱动型电动汽车为研究对象，着力于电动汽车动力系统的匹配研究。首先本文概述了选题意义和国内外电动汽车技术的发展状况；接着描述了电动汽车组成结构和各类电动汽车驱动形式，并选取了外转子式轮毂电机驱动方式；然后对电动汽车各类专用电机进行了充分的研

2、究讨论，将电机按直流与交流分成两大类，逐项说明，并选取了永磁无刷直流电动机作为轮毂电机；在选取了驱动形式和电机种类后，以在售的知豆小型电动车为原型，设计计算轮毂电机参数；最后，运用时下最流行的电动汽车仿真软件ADVISOR2002进行电动车的模拟仿真，验证了设计的合理性。关键词：轮毂电机；永磁无刷直流电机；电动汽车；ADVISOR2002V电动汽车驱动方式与驱动电机研究ResearchonelectricvehicledrivingmodeanddrivingmotorAbstractWithChina'sgrowingairpollutionandtheserioussh
