The invention relates to a motor speed distortion detection method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining a target pulse signal outputted by a target motor, and determining a first target signal sequence outputted by the target motor based on the target pulse signal; grouping the pulse signal values in the first target signal sequence based on a time sequence to obtain a plurality of groups; carrying out system conversion processing on the pulse signal values in the plurality of groups to obtain a second target signal sequence; traversing each conversion value in the second target signal sequence, and under the condition that the currently traversed conversion value is inconsistent with a preset signal value, updating the accumulated speed sudden change frequency of the target motor; and determining the speed distortion of the target motor under the condition that the accumulated speed sudden change frequency is greater than a preset sudden change
