10. The high-efficiency motor and maintenance method convenient for maintenance according to claim 1, characterized in that: The following steps are involved: S1. First, insert the third T-shaped protrusion (19) into the third T-shaped groove (18) so that the third enclosure (5) is snap-fitted and installed on the side of the fourth enclosure (6). Then, insert the fourth T-shaped protrusion (21) into the fourth T-shaped groove (20) so that the first enclosure (3) is snap-fitted and installed on the upper surface of the fourth enclosure (6). Then, insert the second T-shaped protrusion (17) into the second T-shaped groove (16) and simultaneously insert the first T-shaped protrusion (15) into the first T-shaped groove (14) so ​​that the third enclosure (5) is snap-fitted and installed on the side of the fourth enclosure (6). The second enclosure (4) is snap-fitted and installed between the first enclosure (3) and the third enclosure (5), and then the first reinforcement ear block (27) and the second reinforcement ear block (28) can be fixedly connected by bolts, the third reinforcement ear block (29) and the fourth reinforcement ear block (30) can be fixedly connected by bolts, the fifth reinforcement ear block (31) and the sixth reinforcement ear block (32) can be fixedly connected by bolts, and the outer bottom of the fourth enclosure (6) and the outer bottom of the third enclosure (5) can be fixedly connected by bolts. S2. At this time, the front cover (7) is fixed to the detachable casing (2) by bolts. Before fixing, it is necessary to ensure that the first '-shaped protrusion (22) is embedded in the first '-shaped groove (23). Then, the motor body (1) is snap-fitted and installed in the detachable casing (2). Then, the cover plate (9) can be fixed to the detachable casing (2) by bolts. Before fixing, it is necessary to ensure that the second '-shaped protrusion (39) is embedded in the second '-shaped groove (40). Then, the intake fan (12) and the exhaust fan (13) are fixed to the upper surface and the lower surface of the support rod (33) by bolts respectively. At this time, the support rod (33) is fixed to the inner wall of the fixing frame (10) by bolts. Then, the rear cover (11) is fixed to the edge of the fixing frame (10) by bolts. Then, the filter screen cover (26) is fixed to the edge of the vent hole of the rear cover (11) by bolts. S3. If the device fails or needs to be repaired during long-term use, the bolts on the front cover (7) can be unscrewed, and then the front cover (7) can be removed from the detachable casing (2) to check whether the front cover (7) is excessively worn and needs to be replaced. At the same time, the motor body (1) can be removed from the detachable casing (2) and the motor body (1) can be repaired or maintained. At this time, it is also possible to check whether the inner wall of the detachable casing (2) is damaged. If so, the specific part of the casing can be replaced accordingly. If the cover plate (9) is worn, the bolts on the cover plate (9) can be removed and the cover plate (9) can be replaced. S4.
