Abstract
The invention belongs to the field of motors and particularly discloses a motor magnetic ring, a motor and a washing machine. The motor magnetic ring is composed of a hollow inner hole, a metal bracket fittingly matched with a rotating shaft, and a non-metallic magnetic ring formed on the metal bracket through the injection molding process. The metal bracket comprises a substrate, a sleeve convexly arranged at the middle part of the substrate, and an annular convex edge convexly arranged at the outer edge of the substrate. The hollow inner hole penetrates through the sleeve and the substrate. The non-metallic magnetic ring is formed on the annular convex edge and the substrate through the injection molding process. According to the technical scheme of the invention, the non-metallic magnetic ring and the rotating shaft do not directly match each other. Meanwhile, the non-metallic magnetic ring is formed on the annular convex edge and the substrate through the injection molding process. In this way, when the motor magnetic ring is to be installed onto the rotating shaft, no outwardly expanding stress is applied onto the non-metallic magnetic ring. Therefore, the non-metallic magnetic ring is free from cracking. During the rotating process of the rotating shaft, the centrifugal force applied onto the non-metallic magnetic ring is transferred onto the annular convex edge. As a result, the condition that the motor does not run due to the cracking/shedding state of the non-metallic magnetic ring is avoided.
Description
Technical field
The invention belongs to machine field, particularly relate to motor magnet ring, there is the motor of this motor magnet ring and there is the washing machine of this motor.
Background technology
Motor magnet ring is mainly used in for control circuit board detection with the position determining rotor magnetic pole, in its brshless DC motor being mainly used in internal rotor or permagnetic synchronous motor.Particularly, brshless DC motor or permagnetic synchronous motor at work, mainly by control circuit board to stator winding electrifying, and its alive size, direction relevant to the position of rotor magnetic pole.When rotor magnetic pole is in a certain specific position, in stator winding, correspondence need pass into a certain electric current with specific direction and specific size matched with it, like this, brshless DC motor or permagnetic synchronous motor can export drag torque sustainedly and stably and carry out driving loaded work piece, just need control circuit board can detect the position of rotor magnetic pole exactly thus.But, part brshless DC motor or permagnetic synchronous motor limit by structure space, control circuit board can not direct detection to the position of rotor magnetic pole, therefore, need to set up a magnet ring, determined the position of rotor magnetic pole for control circuit board by the position of detection magnet ring magnetic pole.Wherein, magnet ring and rotor are installed in same rotating shaft, and there is a certain positional relationship in magnet ring magnetic pole and rotor magnetic pole, like this, by this specific position relationship, as long as the position of magnet ring magnetic pole can be detected, the position of rotor magnetic pole can be determined, thus correctly can apply the electric current corresponding with rotor magnetic pole position to stator winding.
In conventional art, magnet ring is made into integration by nonmetallic materials, and it is directly set in rotating shaft by interference fit (tight fit) mode.This magnet ring has the following disadvantages in a particular application: the tight fit mode of magnet ring and rotating shaft, magnet ring can be made to be installed on to have after in rotating shaft the power that outwards expands in its endoporus thus easily cause magnet ring to ftracture.Like this, when machine operation, the effect by centrifugal force makes the cracking degree of magnet ring to strengthen gradually until break completely and come off from rotating shaft, and then makes control circuit board cannot detect the position of rotor magnetic pole, finally makes motor normally to work.
As shown in Figure 6 and Figure 7, in order to overcome the weak point of above-mentioned conventional art middle magnetic ring design, prior art proposes following technical scheme: in the endoporus of nonmetal magnet ring 12 ＇, set up non-magnetic metal lining 11 ＇, then this nonmetal magnet ring 12 ＇ is set on rotating shaft 31 ＇ by metal lining 11 ＇ in friction tight mode, the outside expansive force produced due to its tight fit acts directly on metal lining 11 ＇, instead of directly act on nonmetal magnet ring 12 ＇'s, therefore, it effectively improves the problem of Cracking of nonmetal magnet ring 12 ＇ to a certain extent.But this technical scheme still has the following disadvantages in a particular application:
(1) this magnet ring designs and fails thoroughly to solve the problem of Cracking of nonmetal magnet ring 12 ＇, reason is: nonmetal magnet ring 12 ＇ is pressed on after on rotating shaft 31 ＇ by metal lining 11 ＇ cover, metal lining 11 ＇ can produce the distortion of microcosmic equally, this distortion can cause the binding site place of nonmetal magnet ring 12 ＇ and metal lining 11 ＇ to produce microcraking, like this, after motor long-term work, effect microcraking by centrifugal force can become large gradually, and then result in magnet ring break, the depart from situation of rotating shaft 31 and occur, the idle situation of motor finally can be caused to occur.
(2) this magnet ring forms axial magnetic field, and the magnetic line of force of its axis closes through air, this closed magnetic line of force is specifically by the first side magnetic line of force 101 ＇, the second side magnetic line of force 102 ＇, the 3rd side magnetic line of force 103 ＇ and the 4th side magnetic line of force 104 ＇ encloses formation, the the first side magnetic line of force 101 ＇ is wherein only had to be arranged in nonmetal magnet ring 12 ＇, and the second side magnetic line of force 102 ＇, the 3rd side magnetic line of force 103 ＇ and the 4th side magnetic line of force 104 ＇ is arranged in air, because its most of magnetic line of force is arranged in air, therefore, its magnetic permeability is lower, magnet ring magnetic field is more weak, like this, the rotor-position that control circuit board can be made to detect and the physical location deviation of rotor relatively large, and then the performance degradation of motor can be made.
Summary of the invention
