Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, stator punching of the present invention, stator core and motor are further elaborated.Should be appreciated that specific embodiment described herein, only for explaining the present invention, is not intended to limit the present invention.
As shown in Figure 1, motor one embodiment of the present invention is 6 utmost point motors, motor has housing 1 and is positioned at the end cap 2 of housing 1 both sides, housing 1 surrounds a cavity with end cap 2, stator 3 and rotor 4 are installed in cavity, stator 3 has stator core and around the coil in stator core, rotor 4 is arranged in stator 3, and can relative stator 3 rotate.Armature spindle 5 is arranged in rotor 4, and with rotor 4 interference fit, under the drive of rotor 4, rotate, thus outside outputting power.
With reference to Fig. 2 and Fig. 3, stator core is overrided to form by multi-disc stator punching 30,12 stator tooths 32 that stator punching 30 comprises circular yoke portion 31 and the radial circumference direction along stator punching 30 is extended from yoke portion 31, stator tooth 32 has tooth root and tooth top, between two adjacent stator tooths 32, form stator slot 33, and stator punching 30 has the interior circular hole 34 of hollow, and stator slot 33 has bottom land and notch, flat oblique shoulder groove or dovetail groove that stator slot 33 narrows for notch place.Preferably, notch is parallel notch, and width of rebate D is 1.5 millimeters～2.5 millimeters, is preferably 1.8 millimeters～2.2 millimeters.
