Description

A kind of magneto

The utility model is a kind of magneto, belongs to the improvement technology of magneto.

Existing magneto complete machine poor performance, leakage field is big, the permanent magnet utilance is low, power is little, only is confined to certain scope of application and is used for the low capacity synchronous machine, fails to satisfy actual needs.

The purpose of this utility model is to overcome above-mentioned shortcoming and provides a kind of complete machine performance good, and leakage field is little, permanent magnet utilance height, and power is big, the novel permanent magnetic motor of low capacity synchronous machine in can be widely used in.

Structural representation of the present utility model as shown in the figure, by including stator, rotor, its rotor includes rotor yoke iron (1), magnetic pole (2), pole shoe (3), rotor yoke iron (1) is the longitudinal bodies of even number regular polygon for cross sectional shape, magnetic pole (2) is rectangular cubical permanent magnet, and it laterally places on each limit of rotor yoke iron (1), and adjacent polarity is opposite, pole shoe (3) places on the magnetic pole (2), and magnetic pole (2), pole shoe (3) are affixed by connector and rotor yoke iron (1).

Above-mentioned magnetic pole (2) can be an integral body, also can be formed by the uniform bonding of the little rectangle cube of polylith, so that magnetize.

Overall performance of the present utility model is good, and the sectional area of magnetic pole is big, permanent magnet utilance height, the power of motor is big, and leakage field is few, the synchronous machine of low capacity in can be widely used in, and it is simple in structure, easy for installation, the mechanical strength height, inertia is little, the efficient height, the power factor height, good energy-conserving effect, easy to maintenance.

Describe concrete structure of the present utility model and working condition in detail below in conjunction with accompanying drawing:

Fig. 1 is the structural representation of the utility model rotor.

Fig. 2 is the left view of Fig. 1.
