Description
Technical field
The utility model relates to a kind of novel motor, is a kind of on existing motor one deck stator structure basis, increases the multi-layer stator motor of one deck stator again in centre of rotor.
Background technology
Existing in the world at present motor, critical piece all is made up of stator and rotor.With common DC motor is example, sees Fig. 1, and the outside is respectively two opposed polarity stators of DC motor, is made up of permanent magnet.Inside is the rotor of DC motor, is made up of electromagnet.When motor was worked, the work magnetic direction was shown in Fig. 1 black arrow, and arrow is represented " N " utmost point, arrow tail representative " S " utmost point.Because intrinsic homopolar-repulsion, the heteropole in magnetic field inhaled characteristic mutually, make stator produce repulsive forces, two heteropolarity magnetic poles of level in the rotor are produced attractions to vertical two same polarity magnetic poles in the rotor, magnetic field force forces the direction rotation of rotor along the white arrow indication, after rotating to 180 degree, electromagnet in the rotor is supplied with reverse current, constantly repeat thus, motor just constantly rotates.By parity of reasoning, and the main feature of existing motor is to have only one deck stator and the rotor that solid working shaft constitutes.
Summary of the invention
The purpose of this utility model provides a kind of motor of multi-layer stator, the rotor of this motor is a hollow-core construction, central authorities in the rotor hollow-core construction are provided with the stator that permanent magnet constitutes again, under the situation that consumes same electric energy, bigger power output can be arranged, improve the electromechanical conversion efficiency of motor effectively, saved the energy.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of multi-layer stator motor comprises stator and rotor, it is characterized in that: the rotor of this motor is a hollow-core construction, also is provided with the stator that is made of permanent magnet in the central authorities of rotor hollow-core construction.
Rotor of output shaft axle is hollow sleeve, and stator is fixedlyed connected with motor casing, non-rotary axis, and rotor coil is fixed on the iron core, iron core and hollow sleeve connect as one, be supported on the axis by bearing or bearing shell, the outer stator by permanent magnet constitutes is fixed on the shell.
Compared with prior art, the beneficial effects of the utility model are: this motor is provided with the stator that permanent magnet constitutes again in the central authorities of rotor hollow-core construction, therefore, rotor is at synchronization, be subjected to the repulsive force and the attraction of inside and outside two-layer stator simultaneously, like this, rotor is resulting revolving force in motion process, under the situation of not considering mechanical loss, almost increased by one times.So the utility model is compared with existing common motor, under the situation that consumes same electric energy, bigger power output can be arranged, improved the electromechanical conversion efficiency of motor effectively, saved the energy.
