摘要
由于变频调速电机的运行频率是可变的 ,而传统的感应电机的电磁计算程序都是在电机额定频率下进行计算的 ,并不完全适用低频和高频时的情况。本文根据交流电机变频调速的基本理论 ,提出了一种定子电压和输出功率“双反馈”设计方案。
The operating frequency of variable frequency adjustable speed motor is variable, and the traditional electromagnetic calculation of induction motor is done at rated frequency, so the traditional calculation program is not suitable for the calculation of motor under the conditions of low frequency and high frequency. Based on the basic theory of variable frequency adjustable speed for induction motor, this paper presents a new design scheme 'stator voltage and output double feedback'.
