Description
Technical field
The utility model relates to a kind of motor case and stator structure, particularly, relates to a kind of motor case that can locate and stator.
Background technology
Motor (English: Electric machinery, is commonly called as " motor ") refers to a kind of calutron of realizing electric energy conversion or transmit according to the law of electromagnetic induction.In circuit with the old standard D of alphabetical M() represent.Its Main Function is to produce driving torque, as the power source of electrical appliance or various machineries.Generator represents with alphabetical G in circuit.Its Main Function is to utilize mechanical energy to be converted into electric energy, at present the most frequently used, utilizes the pushing generator rotors such as heat energy, water energy to generate electricity.
Motor generally consists of stator, rotor, casing, other annex etc.Part fixing in motor is called stator, has installed in the above the static main pole of paired DC excitation; And rotating part is rotor, to install armature winding in the above, after energising, produce induced electromotive force, serve as rotating magnetic field, produce electromagnetic torque and carry out power conversion.The structure of motor is generally: most external is provided with casing, and the inner side of the formed inner space of casing is fixed wtih stator, and the inner side of stator is provided with the inner peripheral surface of stator and is maintaining certain distance, the rotor that can be rotated.
As shown in Figure 1, the devices such as one of the general employing of current motor or several alignment pin or bolt, respectively through motor casing and stator, fix casing and stator, to prevent that motor stator from relatively rotating or axial endplay.But this structure, manufacturing and the equal more complicated of fit on, can increase cost and engineering time.
Utility model content
The purpose of this utility model is to provide a kind of casing for motor and stator, and this stator can be fixed with respect to this casing, has feature simple in structure, that do not need extra fixture, be easy to processing and assemble simultaneously.
In order to achieve the above object, the utility model provides a kind of motor case that can locate and stator, described stator is arranged on the inside of described casing, wherein, the outer circumference surface of described stator is provided with convex tendon, on the medial surface of described casing, in the position of the described convex tendon of correspondence, be provided with groove, described convex tendon and described groove size are suitable.
