Detection method, system and equipment for three-phase driver, and readable storage medium

The invention discloses a detection method for a three-phase driver. The method comprises the following steps that: obtaining the phase current of each phase of a three-phase motor; judging whether the sum of the current of all phases meets a preset condition or not; and if the sum of the current of all phases does not meet the preset condition, judging that a fault transistor is in the presence in the three-phase driver, and controlling all transistors in the three-phase driver to be off. By use of the detection method, whether exceptional current caused by the fault transistor is in the presence in the three-phase driver or not can be detected, the detection method has the advantages of simple detection process, low detection cost and high reliability, and a difficulty for subsequently overhauling the three-phase driver is lowered. The invention also discloses a detection system and equipment for the three-phase driver, and a readable storage medium, and also has the above beneficialeffects. 本发明公开了种三相驱动器检测方
