Abstract
The paper is devoted to the study of optimal braking modes by asynchronous electric drive using the maximum principle. The optimization criterion is the minimum square of the voltage supplying the electric motor. The controlling influences were the frequency and amplitude of the supply voltage. A mathematical model of a generalized electric machine was used in the calculations. It is determined that for cases when it is necessary to reduce the braking time of an asynchronous electric drive in accordance with the operating conditions of electrical equipment, it is necessary to take into account that reducing the braking time will lead to an increase in electrical losses in the windings of an asynchronous motor and an increase in the amplitude values of current and electromagnetic torque. Increasing the braking time will reduce electrical losses. The dependence of electrical losses in the windings of an asynchronous motor on the optimal braking time is not linear, therefore, it is advisable to choose the braking time on a flat section of this dependence.
