| description | The invention discloses a current sampling delay time measurement method, system and device, and belongs to the technical field of motor control. The method is applied to a current sampling delay time measurement system, and comprises the following steps: controlling a tested motor to enter an uncontrollable rectification state; controlling a motor controller of the test accompanying motor to adjust the rotating speed of the test accompanying motor so as to adjust the working current frequency of the tested motor to the target frequency; the motor controller of the tested motor is controlled to record the sampling current of the tested motor, and meanwhile, a level adjusting command is sent to the motor controller of the tested motor, so that the level of an output port, connected with the oscilloscope, of the motor controller of the tested motor is changed; triggering an oscilloscope to synchronously obtain the reference electric signal of the measured motor measured by the reference electric signal measurin |
