Description
Technical field
The present invention relates to field of mechanical technique, and in particular to a kind of permanent magnet.
Background technology
Namely without under externally-applied magnetic field, the object of itself magnetic can be kept for a long time as its name suggests for permanent magnet.According to
Material is unusual can be kept 10 years as long as, and permanent magnet is available to have ferromagnetic material, and such as iron, nickel is made.Such as
The motor of generator includes many permanent magnets, and these permanent magnets interact to produce electric power with least one coil.Text
Offer EP 1076921A1 and describe a kind of magnet piece with cross-sectional geometry.The geometry corresponds to sinusoidal
Half period arc.It is extremely difficult and expensive to manufacture this geometry.Even if this approximate also not by cogging torque and ripple
Line torque is reduced to gratifying level.
The content of the invention
Instant invention overcomes above-mentioned shortcoming, and provide a kind of permanent magnet.
To achieve these goals, the present invention is to realize by the following technical solutions：The permanent magnet include daughter,
Parent, connecting portion, magneton portion, daughter backplane, female bottom plate and magnetic mother portion, the daughter and the matching of parent specification, the left end of daughter are set
Daughter backplane is put, daughter backplane is connected as one by connecting portion and magneton portion, right-hand member sets female bottom plate, the left end of female bottom plate in parent
Center color sets magnetic mother portion；The connecting portion, magneton portion and daughter backplane are integrally formed；Female bottom plate and magnetic mother portion one into
Type；The daughter backplane is identical with the specification of female bottom plate；The specification matching in the magneton portion and magnetic mother portion.
It is preferred that, the connecting portion is cylinder.
It is preferred that, the longitudinal cross-sectional area of the connecting portion is the 0.7~0.9 of the longitudinal cross-sectional area of daughter backplane
Times.
It is furthermore preferred that the longitudinal cross-sectional area of the connecting portion is 0.8 times of the longitudinal cross-sectional area of daughter backplane.
It is preferred that, the longitudinal cross-sectional area in the magneton portion is the 0.9~0.98 of the longitudinal cross-sectional area in magnetic mother portion
Times.
It is furthermore preferred that the longitudinal cross-sectional area in the magneton portion is 0.95 times of the longitudinal cross-sectional area in magnetic mother portion.
The beneficial effects of the invention are as follows：It is simple in construction, during for motor, magnet volume is reduced in motor, is reduced
Harmonic wave, adds magnetic density, adds electric efficiency, increases the service life.
