The invention discloses a motor fault judgment method, system and device and a storage medium. The motor fault judgment method comprises the steps that a voltage sampling signal is acquired, a first logic value is generated through the voltage sampling signal and a first overvoltage threshold value, and a second logic value is generated through the voltage sampling signal and a second overvoltage threshold value; acquiring a fault detection logic value; the first logic value, the second logic value and the fault detection logic value serve as input, and a third logic value and a fourth logic value are generated through a logic operation model; and generating a first fault judgment result, a second fault judgment result or a third fault judgment result based on the third logic value and the fourth logic value.

    本发明公开了一种电机故障判断方法、系统、设备及存储介质。电机故障判断方法包括:获取电压采样信号,通过电压采样信号和第一过压阈值生成第一逻辑值,通过电压采样信号和第二过压阈值生成第二逻辑值;获取故障检测逻辑值;将第一逻辑值、第二逻辑值、故障检测逻辑值作为输入,通过逻辑运算模型生成第三逻辑值、第四逻辑值;基于第三逻辑值、第四逻辑值生成第一故障判断结果、第二故障判断结果或者第三故障判断结果。
