Two adjacent edges of arbitrary one magnet unit for magnetizing in the clockwise direction are respectively set to be a magnet unit which is vertical to the paper surface and magnetizes inwards and a magnet unit which is vertical to the paper surface and magnetizes outwards, and two adjacent edges of arbitrary one magnet unit which is vertical to the paper surface and magnetizes outwards are respectively set to be a magnet unit for magnetizing in the clockwise direction and a magnet unit for magnetizing in the counter-clockwise direction. The invention also provides a motor applying the magnetic steel. For adopting the magnet unit for magnetizing in the rotation direction, the structure can enable the motor to obtain larger driving force and acceleration.
Description
[technical field]
The present invention relates to a kind of magnet steel.
[background technology]
Along with the development of permanent magnetism new material, microelectric technique, automatic control technology and power electronic technology, motor obtains significant progress.Motor utilizes electronic commutation to replace traditional mechanical commutation, it relies on dependable performance, do not have wearing and tearing forever, failure rate is low, and volume is little, the efficient advantages of higher,, develop rapidly to Aero-Space, medical treatment, information, household electrical appliances and industrial automation field gradually by initial military field.
The magnet steel of correlation technique is annular, and it comprises first group of magnet steel and second group of magnet steel, and every group of magnet steel is provided with three magnet unit.Wherein, the magnetizing direction of first group of magnet steel is vertical paper (promptly the magnetic pole away from paper is the S utmost point) inwards, and the magnetizing direction of second group of magnet steel is vertical paper outwards (promptly the magnetic pole away from paper is the N utmost point).First group of magnet steel and second group of interlaced setting of magnet steel.
Yet in the motor of correlation technique, the magnet steel structure is evenly distributed the magnetic line of force in the magnetic circuit, and the magnetic field that obtains so also is uniformly, and therefore the tripping force of the motor that obtains is limited.
Therefore, be necessary to provide a kind of motor of new magnet steel structure, make it obtain bigger actuating force and acceleration.
[summary of the invention]
The technical problem that the present invention need solve provides a kind of motor of new magnet steel structure.
According to above-mentioned technical problem, the present invention has designed a kind of magnet steel.Described magnet steel is provided with the vertical paper of the even number magnet unit that magnetizes of the magnet unit that magnetizes of direction and vertical paper outward direction inwards.Wherein, described magnet steel also is provided with even number clockwise direction magnet unit that magnetizes and the magnet unit that counterclockwise magnetizes.The magnet unit that the magnet unit that magnetizes with any described clockwise direction is adjacent is respectively the described vertical paper magnet unit that magnetizes of the magnet unit that magnetizes of direction and described vertical paper outward direction inwards; Be respectively the magnet unit that magnet unit that described clockwise direction magnetizes and described counter clockwise direction magnetize with any described vertical paper magnet unit that the magnet unit that magnetizes of direction is adjacent inwards.
Preferably, described magnet steel is the cylindric of hollow.
Preferably, the described magnet steel of described magnet unit five equilibrium.
Preferably, described magnet steel is provided with 12 magnet unit.
Preferably, the present invention has also designed a kind of motor, wherein, described motor application as magnet steel of the present invention.
Compare with correlation technique, the magnet unit that motor of the present invention has adopted direction of rotation to magnetize owing to magnet steel, this structure can make described motor obtain bigger actuating force and acceleration.
[description of drawings]
Fig. 1 is the cut-away view of motor of the present invention.
Fig. 2 is a magnet steel vertical view of the present invention.
[embodiment]
The invention will be further described below in conjunction with drawings and embodiments.
As depicted in figs. 1 and 2, described magnet steel 2 is provided with the vertical paper of the even number magnet unit 21 that magnetizes of the magnet unit 23 that magnetizes of direction and vertical paper outward direction inwards.Wherein, magnet steel 2 also is provided with even number clockwise direction magnet unit 22 that magnetizes and the magnet list 24 that counterclockwise magnetizes.
The magnet unit 22 adjacent magnet unit (not label) that magnetize with any described clockwise direction are respectively the described vertical paper magnet unit 21 that magnetizes of the magnet unit 23 that magnetizes of direction and described vertical paper outward direction inwards, promptly adjacent one side of the magnet unit 22 that magnetizes when clockwise direction is set to the vertical paper magnet unit 23 that magnetizes of direction (or vertical paper outward direction magnetize magnet unit 21) inwards, one side the then adjacent in addition magnet unit 21 that vertical paper outward direction magnetizes (or vertical paper the magnet unit 23 that magnetizes of direction) inwards that is set to; Be respectively the magnet unit 24 that magnet unit 22 that described clockwise direction magnetizes and described counter clockwise direction magnetize with any described vertical paper magnet unit that the magnet unit that magnetizes of direction 23 is adjacent inwards, promptly be set to the magnet unit 22 (or the magnet unit 24 that counterclockwise magnetizes) that clockwise direction magnetizes in adjacent one side of the magnet unit 23 that magnetizes of direction inwards when vertical paper, the magnet unit 24 that then adjacent another side is set to counterclockwise to magnetize (or clockwise direction magnetize magnet unit 22); Arbitrarily the adjacent both sides of the magnet unit 22 that magnetizes of clockwise direction are set to the vertical paper magnet unit 21 that magnetizes of the magnet unit 23 that magnetizes of direction and vertical paper outward direction inwards respectively,
The magnet steel 2 of the present invention's design is the cylindric of hollow, and magnet unit (not label) is provided with 12 and the described magnet steel of magnet unit five equilibrium.
The present invention has also designed a kind of motor 1 of using above-mentioned magnet steel 2.
Motor of the present invention has adopted magnet steel of the present invention, and described magnet steel is owing to be provided with the magnet unit that direction of rotation magnetizes.This structure can make the magnetic line of force in the magnetic field to the monolateral gathering in magnetic field, rather than both sides all distribute, thereby strengthens monolateral magnetic field intensity, simultaneously the magnetic field intensity of weakened field another side.Finally reach the actuating force and the acceleration that strengthen described motor.
Above-described only is embodiments of the present invention, should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the invention design, can also make improvement, but these all belongs to protection scope of the present invention.
