Abstract
The invention relates to an electric motor comprising a stator, a rotor and a retaining frame for connecting the stator and the rotor. A vibration absorber which is a super-elastomer or a linear elastomer is arranged at the connecting position of the retaining frame and the stator. The invention provides the electric motor with small noise and little internal vibration.
Description
Technical field
The present invention relates to a kind of motor, relate in particular to a kind of motor that between stator and retainer, is provided with vibration absorber.
Background technology
The stator of prior electric machine is connected with rotor through retainer; There is following shortcoming in this kind version: because stator and retainer are rigidly connected; The vibrations of rotor are directly passed to stator, make stator vibrations big and noise is also big, and influence each other between stator and the rotor.The damping of prior electric machine all realizes through damping device is installed between motor casing and motor bed-plate; This kind version has just effectively been improved motor vibrations influence to external world; Its noise is still very big, and fundamentally solves the difficult problem that motor interior vibrations are big, noise is big, again and; Influence each other between the rotor of motor and the stator, be unfavorable for the normal operation of motor.
Summary of the invention
The objective of the invention is to overcome the defective that prior art exists, provide a kind of noise little, and the little motor of inner vibrations.
The technical solution adopted for the present invention to solve the technical problems is: a kind of motor, comprise stator, rotor, and the retainer that is used to connect said stator and rotor, the junction of said retainer and stator side is provided with vibration absorber.
Further, the side of the iron core of said stator is provided with at least two location holes, and said retainer is provided with respectively and said each position of positioning hole, shape, big or small corresponding cylinder, said each cylinder be inserted in respectively with its corresponding positioning hole in.
Further, described vibration absorber is a hyperelastic body, and this hyperelastic body is a thermoplastic elastic rubber.All be socketed with thermoplastic elastic rubber on said each cylinder, this thermoplastic elastic rubber is between stator and retainer, and the one of which side is against on the stator side, and its opposite side is against on the joint face of retainer and cylinder.
According to another embodiment of the invention, comprise further that described vibration absorber is a linear elastomer; Described linear elastomer is a Hookean spring; All be socketed with Hookean spring on said each cylinder, this Hookean spring is between stator and retainer, and the one of which side is against on the end face of location hole, and its opposite side is against on the joint face of retainer and cylinder.
Beneficial effect of the present invention: the invention solves the defective that exists in the background technology; Between the stator retainer of motor and drive system casing, vibration absorber is set; The vibrations of drive system generation are just weakened by vibration absorber widely like this; It is very few to influence each other between stator and the drive system, also greatly reduces noise.
