Abstract: An air blower, including a volute, a centrifugal wind wheel, and a motor. The volute includes an end plate, a side plate extending from an edge of the end plate, and a cavity formed by the end plate and the side plate; the centrifugal wind wheel is disposed in the cavity; the end plate includes an air inlet, and two ends of the side plate are disposed side by side to form an air outlet; the end plate further includes a support beam opposite to the air inlet, and the motor is disposed on the support beam.

Abstract: A stator lamination includes a middle part, an annular yoke, and a plurality of stator teeth. The middle part includes a central hole. The plurality of stator teeth extend from the inner side of the annular yoke and are evenly distributed. A wire slot is formed between every two adjacent stator teeth, whereby the annular yoke includes a plurality of wire slots. Each of the plurality of stator teeth includes a tooth root and a pole shoe disposed at one end of the tooth root. The stator lamination has an outer diameter ranging from 61.75 mm to 68.25 mm, and the central hole has a diameter ranging from 31.6 mm to 35 mm. The plurality of wire slots are evenly distributed around an edge of a circle, and the bottom part of each wire slot is tangent to the circle.
