Abstract

Способ измерения намагничивающего тока асинхронного двигателя путем подключения его на номинальное по частоте и амплитуде напряжение, измерения и регулирования частоты вращения ротора до совпадения ее с частотой вращения поля статора, кратной частоте питания, и измерения при этом намагничивающего тока в фазе статора, отличающийся тем, что, с целью упрощения способа, перед измерением намагничивающего тока кратковременно синфазно переключают двигатель на повышенное по частоте и амплитуде напряжение, а после разгона ротора до частоты вращения, равной 1,05-1,5 частоты вращения поля статора, вновь переключают синфазно двигатель на номинальное напряжение и частоту питания.A method for measuring the magnetizing current of an induction motor by connecting it to the nominal frequency and amplitude voltage, measuring and controlling the rotor speed to match it with the frequency of rotation of the stator field, a multiple of the supply frequency, and measuring the magnetizing current in the stator phase, characterized in that , in order to simplify the method, before measuring the magnetizing current, the motor is briefly in phase switched to an increased voltage and frequency, and after the acceleration of the rotor to the frequency A setting equal to 1.05-1.5 frequency of rotation of the stator field, again switch the motor in phase to the rated voltage and frequency of power.
