Description
Technical field
The utility model relates to a kind of mixed excitation claw-pole brushless electric machine.
Background technology
Electricity excitation claw-pole motor is owing to can regulating easily DC excitation, thus aspect flux control, there is the advantage that magneto does not reach, but there is brush-slip ring structure in it, and reliability is poor, excitation loss is larger.Magneto also has advantages of a series of uniquenesses owing to having cancelled brush, slip-ring device, as high in efficiency, simple in structure, volume is little etc., but the air-gap field of magneto is determined by magnet steel and magnetic circuit magnetic conductance, is in operation and almost keeps constant, regulates difficulty.
Summary of the invention
The problem existing for solving prior art, the utility model provides a kind of pawl extremely wide formula composite excitation brushless claw pole motor, and its technical scheme of taking is:
Comprise casing, be located at the end cap at casing two ends, and be located at the excitation support in casing, stator and pawl utmost point rotor, on stator, be socketed with magnetic shield, magnetic shield is fixed on the inwall of casing, pawl utmost point rotor is two, they snap together mutually, and fix by the rotating shaft through its center, each pawl utmost point rotor has a plurality of pawl utmost points, pole-face width and the thickness of each pawl utmost point are all identical, in each pawl utmost point rotor, the utmost point of adjacent two pawl interpolars palm indent is near rotating shaft, space between the extremely epitrochanterian pawl utmost point being adjacent of the extremely epitrochanterian pawl utmost point of arbitrary pawl and another pawl is embedded with rectangular permanent magnet, excitation support is two, be separately fixed on end cap inwall, on each excitation support, be fixed with respectively the excitation winding that is cascaded.
The excitation mode that the utility model adopts permanent magnetism and electric excitation to combine, produces magnetic field jointly by permanent magnet and excitation winding, both can overcome the nonadjustable shortcoming of permanent magnet generator magnetic flux, also can reduce the capacity of excitation winding.In the situation that not increasing exciting current, increase exerting oneself of air gap flux density and motor, improved the efficiency of motor, improved the low speed output characteristic of motor.In addition, adopt brushless structure, improved system reliability of operation.
Accompanying drawing explanation
Fig. 1 is structure half sectional view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, this motor comprises casing 1, is located at the end cap 2 at casing 1 two ends and is located at excitation support 3, stator 4 and the pawl utmost point rotor 5 in casing 1, and end cap 2 divides as a part for motor magnetic circuit with casing 1.Stator 4 is socketed with magnetic shield 6, magnetic shield 6 is fixed on the inwall of casing 1, pawl utmost point rotor 5 is two, they snap together mutually, and fix by the rotating shaft 7 through its center, each pawl utmost point rotor 5 has a plurality of pawl utmost points 8, and pole-face width and the thickness of each pawl utmost point 8 are all identical, in each pawl utmost point rotor 5, the utmost point of 8 of adjacent two pawl utmost points palm indent is near rotating shaft 7, between the consecutive roots palm, axially having certain distance with every magnetic.Space between the pawl utmost point 8 being adjacent on the pawl utmost point 8 on arbitrary pawl utmost point rotor 5 and another pawl utmost point rotor 5 is embedded with rectangular permanent magnet, permanent magnet adopts cutting orientation magnetizing, its magnetic field forms relation in parallel with electricity excitation magnetic field, excitation support 3 is two, be separately fixed on end cap 2 inwalls, on each excitation support 3, be fixed with respectively the excitation winding 9 that is cascaded.
This motor has two magnetic potential sources, is respectively permanent magnet and excitation winding, and wherein permanent magnet provides stationary magnetic field, plays main field; The magnetic field that excitation winding produces, by changing the size and Orientation of electric current, plays the effect of magnetic assist or weak magnetic to permanent magnetic field.During this motor operation, by changing the size and Orientation of excitation winding electric current, can change the intensity of air-gap field.
