Description
Technical field
The utility model relates to a kind of switched reluctance motor, particularly a kind of switched reluctance motor that can reduce noise.
Background technology
Switched reluctance motor comprises casing, stator core, rotor core, winding, axle, and wherein stator core is fitted in the casing, and rotor core is fitted in the axle of motor and goes up and be enclosed within the stator core, rotates with axle.The material of stator core is a silicon steel sheet, the material of casing be generally cast iron, casting just, steel plate, cast aluminium or aluminium section bar etc.Rotor teeth groove number commonly used is 4/2,6/4,8/6,12/8,16/12 etc., and embedding polyphase windings in the stator slot equates as two-phase, three-phase, four phases, five.During machine operation, each winding is taken turns flow-thru electrode successively, and when a phase winding was switched on, the rotor between cog also produced the power that attracts each other radially except that producing tangential force, and its result makes stator core produce ovalizing deflection.During this winding no power, the radial attraction force of rotor between cog disappears, and it is circular that stator core recovers.The distortion of stator core and recovery make it to knock mutually with casing, thereby make switched reluctance motor produce strong noise.
The utility model content
Technical problem to be solved in the utility model provides a kind of can the reduction between casing and the stator core because of knocking the switched reluctance motor of the noise that produces mutually.
The utility model is a kind of switched reluctance motor that reduces noise, comprise casing, be fitted in stator core in the casing, be fitted in axle and go up and be enclosed within the rotor core in the stator core and be embedded in winding on the stator core, stator core and casing are fixed together.
The switched reluctance motor of reduction noise of the present utility model is opened some apertures on the casing, aperture is inboard fixedlys connected by welding or alite paste with the contacted position of stator core, and aperture distributes along the axial and circumferential of casing, and aperture can be different shape.
The switched reluctance motor of reduction noise of the present utility model, the inwall of casing and the outer surface of stator core are bonding by full surface of adhesive or part surface.
The switched reluctance motor of reduction noise of the present utility model, weld respectively or be adhesively fixed the front end of casing and stator core and the rear end of stator core.
The utility model is a kind of switched reluctance motor that reduces noise, adopts casing and stator core are linked together by welding or adhesive, and the mechanical strength of its anti-ovalizing deflection is increased.Switched reluctance motor in the course of the work, because casing and stator core weld by aperture or are bonded together, or by the inwall of casing and the outer surface of stator core are bonded together entirely, reduced the distortion of stator core, avoid knocking of stator core and casing, thereby reduced the noise that switched reluctance motor produces.At switched reluctance motor in the course of the work, because the rear and front end of casing and stator core links together by welding or adhesive respectively, can reduce the distortion of stator core, reduce the intensity of knocking of stator core and casing, equally also can reduce the noise that switched reluctance motor produces.This device also is applicable to other forms of motor, and stepping motor etc. for example can reduce the operating noise of motor equally.
