Abstract
A magnetic steel axial direction of the existing permanent magnet motor is a whole strip, the utility model provides an excitation part of a permanent magnet motor which is provided with a magnetic steel staggered structure, so as to divide the length of the axial direction of the magnetic steel into a plurality of sections which are arranged along the circumferential direction of a magnetic conductor in a staggered way, further to play a role which is similar to an armature iron core chute, reduce the vibration and noise of the motor and add the resistance moment and the special cogging torque of the permanent magnet motor, the utility model is applicable to a plurality of permanent magnet motors, comprising the motors and the generators, DC and AC, brush and brushless; and the utility model has certain practical value.
Description
Technical field
The utility model relates to a kind of motor, is a kind of exciting part of magneto specifically.
Background technology
In the prior art, utilize the armature core skewed slot, can reduce because the slot effect that causes of open slot, thereby reduce the vibration and the noise of motor, reduce the additional drag square, improve electric efficiency.But in magneto, many armature cores are difficult to realize skewed slot, though certain structures energy skewed slot has brought trouble for automatic winding and mechanization rule.Also once tried the tiltedly way of the utmost point, but, therefore be difficult to practicality because of magnet steel and cooperating of magnetic conductor are a solid surface or inclined-plane.
The utility model content
The purpose of this utility model is to provide a kind of exciting part of magneto, and the magnet steel misconstruction of this exciting part can reach the effect close with the armature core skewed slot.
To achieve these goals, the utility model has adopted following technical scheme:
Exciting part with magneto of magnet steel misconstruction is made up of magnet steel and magnetic conductor, it is characterized in that: the axial length of magnet steel is divided into plurality of sections, and every section circumferencial direction along magnetic conductor moves past an angle.
After employing has the exciting part of magnet steel misconstruction, can reduce the vibration and the noise of motor, reduce additional drag square and torque fluctuation, improve potential waveform, can reduce the distinctive location torque of magneto, have certain practical value.
Description of drawings
Fig. 1 is one of the magnet steel structure of existing magneto use (4 utmost point radial);
Fig. 2 is exciting part structural representation of the present utility model (4 utmost point radial);
Fig. 3 is two (4 utmost point tangential) of the magnet steel structure of existing magneto use;
Fig. 4 is exciting part structural representation of the present utility model (4 utmost point tangential).
Embodiment
The utility model is described in further detail with accompanying drawing below.
Fig. 1 is one of existing magnet steel structure, is that magnet steel 1-1 axially is being a whole piece in the illustration with 4 utmost point radials, cooperates with circular arc with magnetic conductor 1-2 surface, forms the exciting part of magneto.
Now with the axial length segmentation of magnet steel, segments is many more, and effect is good more, but technology is complicated more, when taking a lot of work more, so generally be divided into 2 sections cutter sections.Fig. 2 is one of application example of the present utility model, and magnet steel 2-1 axially is divided into 3 sections, along angle of magnetic conductor 2-2 circumferencial direction dislocation, forms a whole then between every section.
Fig. 3 is to be the existing magnet steel structure of example with 4 utmost point tangential, and magnet steel 3-1 is in the groove of magnetic conductor 3-2, and it axially is a whole piece, dots wherein 1 among the figure.Fig. 4 then is a structure of the present utility model, magnet steel 4-1 and magnetic conductor 4-2 are divided into 3 sections vertically, dislocation forms a whole then, is divided into error angle θ total after 3 sections as shown in Figure 4, and the occurrence at θ angle is determined at the needs of various magnetoes by the designer.
The utility model is applicable to various magnetoes, comprises direct current and exchange that motor and generator have brush and brushless.After employing has the exciting part of magnet steel misconstruction, can reduce the vibration and the noise of motor, reduce additional drag square and torque fluctuation, improve potential waveform, can reduce the distinctive location torque of magneto, have certain practical value.
