Подскажите, при включение шпиндель гудит но не крутится, а если слегка толкнуть вал рукой то схватывается и начинает нормально крутиться, в чем может быть проблема?
Возможно пропала одна фаза, если он раньше нормально крутился.
раньше нормально крутился.
там же на выходе инвертора на каждой паре выводов должно быть одинаковое напряжение?
Действительно, один из трех проводов где-то внутри оборвался. жесть, кабелю всего пол года
