The rear cover (11) shows a central hole and more than one of the outlet holes (13); the cover (2) The front opening (12) of the housing (1) is shown with a center hole (21). A rotating shaft (8) is mounted across the inner gap (14) of the housing (1). The rotating shaft (8) has one end (80) which is inserted through the center hole of the rear cover (11) and has a second end (89) which is inserted through the center hole (21) of the cover (2); The cooling fan (4) is attached to the second end (89) of the rotating shaft (8), thus the cooling fan (4) rotates together with the rotating shaft (8). This is characterized by the housing (2) showing more than one number of inlet holes (23) around the center hole (21) of it. The air collection structure (9), which is modified to be attached to the housing (2), has a central hub (90) showing a center hole (91) aligned with the center hole (21) of the housing (2) for the second end (89) of the rotating shaft (8) to pass through it, and an outer ring is made around the central hub (90) 15 and showing more than one number of through holes (93) positioned between the outer ring and the central hub (90) and aligned with the outer hole (23) of the housing (2). As the central part of the rotation, the active airflow created by the cooling fan (4) can flow through the gaps between the rings. The outer ring and central hub (90) of the air collection structure (9) and subsequently flow through the through hole (93) of the air collection structure (9) and the inlet hole (23) of the enclosure (2) to enter the 20-inch (14) space of the housing (1) and finally flow out of the housing (1) through the outlet hole (13) for the reduction of heat generated in the housing (1). 2. The motor of claim 1, whose surrounding walls of the housing (1) show more than one of the inlet holes (10), the enclosure (2) is provided at the outer edge with more than one of the air-catching protrusions (25), each of which is made upright, convex, with a roof (251) and two sloping walls (252, 253) on the two opposite sides of the roof (251). Two sloping walls (252, 253) are made together with the enclosure (2), thus showing the air intake channel (254) between the roof. (251), two inclined walls (252, 253), and enclosure (2), enclosure (2) is fitted to the housing (1). Thus, each of the air intake protrusions (25) is positioned above the inlet hole (10) of the housing (1), and each of the air intakes (254) faces the cooling fan (4), while the outer portion of the airflow created by the cooling fan (4) can flow through the air intakes (254) and the inlet hole (10) of the housing (1) into the inner cavity (14) of the housing (1) for the reduction of heat generated in the housing (1).
