摘　　要：电动机的通风噪声与电动机转速密切相关。为了有效降低通风噪声,对不同风扇的噪声进行测定。考虑在无法进行通风流量测试状态下,按照电机的温升试验来确定该风扇是否符合电机散热要求的方案。通过样机验证,为改进电机结构和降低电机通风噪声提供新的设计思路。The motor wind noise is closely related to the motor speed. To reduce the wind noise effectively, the noises with different types of fan were tested. Considering in the condition of wind flow cannot being measured, it is decided whether the fan meets the demand of motor cooling based on the test of temperature rise for motor. With sample test verification, it provided a new design thinking to realize motor structure improvement and wind noise reduction.
