电动汽车驱动电机额定功率的确定和验证方法

摘要

电动汽车用驱动电机的运行特点为典型的断续周期工作制，其额定参数的确定和验证方法对保证驱动电机的可靠性和避免过设计非常重要。根据驱动电机的运行特点，介绍确定额定功率的方法，提出驱动电机输出能力试验验证方法。%The operating feature of the drive motor for electric vehicle is a typical intermittent periodic duty. The determination and verification method of rated parameters are very important to ensure the reliability of the drive motor and avoid excessive design. Based on the operating characteristics of the drive motor, the method of determining the rated power was introduced and the testing verification methods of the output capability were proposed.
