A method for identifying dysfunction of an inverter-polyphase motor assembly, comprising a plurality of sequential diagnostic processes, each sequential diagnostic process comprising the following steps: an initial configuration step of the inverter (2); an initial configuration step of the phase switches (7); a phase (u, v, w) biasing step; -a voltage measurement step in which the voltage of each phase (u, v, w) is measured; a comparison step, in which the voltage measurement of each phase (u, v, w) is compared with an expected result value; a dysfunction identification step of identifying a dysfunction when the voltage measurement value of one phase differs from the expected result value.

    逆变器‑多相电机组件的功能障碍识别方法,包括多个顺序诊断过程,每个顺序诊断过程包括以下步骤:‑逆变器(2)的初始配置步骤;‑相开关(7)的初始配置步骤;‑相(u、v、w)偏置步骤;‑电压测量步骤,其中测量每个相(u、v、w)的电压;‑比较步骤,其中将每个相(u、v、w)的电压测量值与预期结果值进行比较;‑功能障碍识别步骤,当一个相的电压测量值不同于预期结果值时识别出功能障碍。
