Example Embodiment
[0011] Example 1: Using the same batch of molding slurry, under the same molding, sintering, and testing process conditions, the products made, such as figure 1 Combined with the sample No. 2 in Table 1, a motor magnetic steel, the outer arc of the main body of the magnetic steel is determined according to the motor housing to ensure that the magnetic steel and the motor housing are firmly attached. Both ends of the outer arc surface 1 respectively have an arc surface that transitions with the radian of the outer arc surface, and there is a certain gap between the extension surface of the outer arc surface and this arc surface, and this gap is an air gap, and this arc surface is an air gap transition arc 4, The center of the air gap transition arc 4 is deviated from the center of the outer arc surface 1 of the magnetic steel, and the total width of the air gap (w1-w) is 40% of the total width of the magnetic steel w1 (w1-w) / w1=40%); the outer arc surface of the main body 1 The...
