Claims (5)

------18/12/2017------(OCR) Page 1 of 2 pages. Claims 1. The motor, including the housing (1), the enclosure (2), the shaft (8), and the cooling fan (4), in which the housing (1) has a wall enclosed herein the inner cavity (14) with a front opening (12) and a rear wall (11) opposite the front opening (12). The rear wall (11) shows a center hole and a greater number of outlet holes (13); The cover (2), which closes the front opening (12) of the housing (1), shows the center hole (21). The shaft (8) is mounted across the inner gap (14) of the housing (1). The shaft (8) has one end (80) which is inserted through the center hole of the rear cover (11), and has the other 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) exhibiting a greater number of inlet holes (23) around the center hole (21) of the thing. The air collection structure (9), which is modified to be attached to the housing (2), has a central hub (90) exhibiting 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 the thing, and an outer ring is made around the central hub (90) exhibiting a greater 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 airflow generated by the cooling fan (4) can flow through the gaps between the rings. The outer ring and the 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 housing (2) to enter the inner cavity (14) 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, where the surrounding walls of the housing (1) show a greater number of inlet holes (10), the housing (2) is provided at the outer edge with a greater number of Each of the wind-catching protrusions (25) is constructed on the raised layer of the roof (251) and the two sloping walls (252, 253) on opposite sides of the roof (251). The two sloping walls (252, 253) are constructed together with the casing (2), thus showing the air intake (254) between the roof (251), the two sloping walls (252, 253), and the casing (2). The casing (2) is fitted to the housing (1), thus each of the wind-catching 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), as the outer portion of the airflow created by the cooling fan (4) can flow through the air intake (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). Page 2 of Number 2. Page 3. The motor of claim 2, where a recess (26) is shown between two adjacent things of the air intake protrusion (25), thus some of the outer portion of the airflow created by the cooling fan (4) which does not enter the housing (1) may flow along the outer surface of the enclosure wall of the housing (1) to cool the housing (1). 4. The motor of claim 1, where the enclosure (2) shows a greater number of mounting holes (22), the air intake structure (9) is provided with a greater number of mounting holes (94) that can be inserted into the mounting holes (22) of the enclosure (2), thus the air intake structure (9) is fixed to the enclosure (2). 5. The motor of claim 1, where a sleeve (3) made of magnetically permeable metal is fixed close around the enclosure wall of the housing (1) to improve the efficiency of the motor. ------------ Edited 8/12/2016 1. In a motor, which includes the housing (1), the cover (2), the shaft (8), and the cooling fan (4), where the housing (1) is enclosed by a wall shown here to the inner cavity (14) with a front opening (12) and a rear cover (11) opposite the front opening (12), the rear cover (11) shows a center hole and more than one number of outlet holes (13); the cover (2), which encloses the front opening (12) of the housing (1), shows a center hole (21); the shaft (8) is mounted across the inner cavity (14) of the housing (1), with one end (80) inserted through the center hole of the rear cover (11) and with the other end (89) 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), so the cooling fan (4) rotates together with the rotating shaft (8). This is characterized by the housing (2) exhibiting more than one number of inlet holes (23) around the center hole (21) of the thing. The air collection structure (9), which is modified to be attached to the housing (2), has a central hub (90) exhibiting 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 the thing, and an outer ring is made around the central hub (90) exhibiting 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 the central hub (90) of the air collection structure (9) then flow through the through hole (93) of the air collection structure (9) and the inlet hole (23) of the housing (2) into the inner cavity (14) of the housing (1) and finally out of the housing (1) through the outlet hole (13) for cooling of the heat generated in the housing (1). 2. The motor of claim 1, where the enclosing wall of the housing (1) shows more than one number of inlet holes (10), the enclosure (2) is provided at the outer edge with more than one number of Each wind-catching protrusion (25) is constructed as a raised layer with the roof (251) and the two sloping walls (252, 253) on opposite sides of the roof (251). The two sloping walls (252, 253) are constructed together with the casing (2), thus showing the air intake (254) between the roof (251), the two sloping walls (252, 253), and the casing (2). The casing (2) is fitted to the housing (1), thus each wind-catching protrusion (25) is positioned above the inlet hole (10) of the housing (1), and each air intake (254) faces the cooling fan (4), while the outer portion of the airflow created by the cooling fan (4) can flow through the air intake (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). 3. The motor of claim 2, where the recess (26) is shown between two adjacent ones of the wind-catching protrusion (25), thus some of the outer portion of the airflow created by the cooling fan (4) which does not enter the housing (1) may flow along the outer surface of the enclosed wall of the housing (1) to cool the housing (1). 4. The motor of claim 1, where the housing (2) exhibits more than one number of mounting holes (22), the air storage structure (9) is provided with more than one number of mounting holes (94) that can be inserted into the mounting holes (22) of the housing (2). Thus, the air storage structure (9) is fixed to the housing (2). 5. The motor of claim 1, in which an arm (3) made of magnetically permeable metal is attached close around the enclosed wall of housing (1) to improve the efficiency of the motor.
