摘　　要：本文提出了过最大力矩加速的计算方法及应用，并将力矩几何平均法和转差率几何平均法推广应用到ｍ台同特性或不同特性、同时切除或交替切除电阻的计算上，提出了简单的近似计算公式，从理论上解放了任意台电动机驱动电阻的计算问题。The paper describes the calculation of over acceleration at maximum torque and its application. The torque geometric average and slippage geometric average methods are applied to calculation of resistance when resistors of a number of m electric motors of same or different characters are cut off simultaneously or alternatively. A simple and proximate formula is proposed which has solved theoretically the problem of calculating of drive resistance of any number of motors.
