| description | The invention relates to the technical field of voltage sampling, and provides a bus voltage sampling method and device of a motor controller. The method comprises the following steps: acquiring sampling voltages in one-to-one correspondence with preset bus voltages from a bus voltage sampling circuit of a motor controller according to the preset bus voltages; inputting any target voltage in the sampling voltages into the bus voltage sampling model to obtain an actual bus voltage, comparing the actual bus voltage with a preset bus voltage corresponding to the target voltage, and determining that the deviation between any actual bus voltage and the corresponding preset bus voltage is less than or equal to a preset value, and marking each actual bus voltage as the bus voltage of the motor controller. According to the bus voltage sampling method of the motor controller provided by the embodiment of the invention, the obtained bus voltage can meet the accuracy requirement, and the overall performance of the motor |
