The invention belongs to the technical field of motor, and specifically relates to an end cap structure for a high protection level motor. The end cap structure comprises a motor shell, wherein a left end cap is in tight coupling with the left side of the motor shell; a right end cap is in tight coupling with the right side of the motor shell; a bearing bush is in tight coupling with the revolution center of the left end cap and the right end cap respectively; a dabber is supported on each bearing bush through rotation of a bearing; and two ends of each dabber are sealed among the corresponding bearing bushes through a seal ring respectively. The end cap structure for a high protection level motor is simple in structure and reasonable and ingenious in design, and can effectively widen the application scope of the product by modifying the end cap structure of an existing motor so that the product can be applied outdoors without worry about getting wet in the rain, and the product can be applied in severe conditions, such as oil-water splashing and is provided with a high protection level.
