Abstract
The utility model relates to a brushless synchrnous AC generator, which is used for automobiles. A section of axial gap is positioned between a front magnetic pole (9) which is positioned on a rotor (1) of the utility model and a back magnetic pole (10); exciting current can be introduced by a conducting wire (17) through the gap (13), so the utility model which is independent of electric brushes can work, and the defects of generators with brushes can be overcome.
Description
The utility model relates to the brushless synchronous alternator of a kind of automobile.
In present prior art, various have the exciting current of brush synchronous alternator all to be introduced by brush and slip ring, and the situation of relevant this respect can be understood from the books of telling about motor configuration.This traditional to have the brush alternating current generator to have a noise big, and the life-span is short, shortcomings such as O﹠M inconvenience.
The purpose of this utility model provides a kind of brushless synchronous alternator that does not need brush and slip ring.
Before describing technical solution of the present utility model, at first suppose the generator that work, its stator remains static, and rotor then is in rotation status with respect to scheduling.Traditional having in the brush synchronous alternator, the surfaces of revolution that two pawls are extremely gone up magnetic pole overlaps, therefore when the rotor of brush motor rotated, its pawl utmost point will form the cylinder of a sealing, and the cylinder of this sealing makes any object that remains static can't pass it; But in order to introduce exciting current without brush and slip ring, only way is exactly that lead and the magnet exciting coil of introducing exciting current are all remained static; Obviously static lead is the closing cylinder that can't pass above-mentioned brush motor.In technical solution of the present utility model, the surfaces of revolution of two pawls extremely being gone up magnetic pole along motor axially separately, even two pawls are extremely gone up between the surfaces of revolution of magnetic pole one section space is vertically arranged; So, static lead just can pass this space and introduce exciting current, thereby makes brushless synchronous alternator of the present utility model not need brush and slip ring just can introduce exciting current.
Because brushless synchronous alternator of the present utility model does not rely on slide unit work such as brush and slip ring, thereby has overcome the shortcoming of brush motor.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural map of brushless synchronous alternator of the present utility model.
Fig. 2 is the A-A profile of Fig. 1.
By Fig. 1 and Fig. 2 as seen, brushless synchronous alternator of the present utility model is made up of rotor (1), stator (2), magnet exciting coil (3) and casing parts such as (4).
Rotor (1) is made up of the fore paw utmost point (6), the rear solid end utmost point (7) yoke (8) that are enclosed within the rotating shaft (5).Preceding magnetic pole (9) is arranged on the fore paw utmost point (6), back magnetic pole (10) is arranged on the rear solid end utmost point (7); The face of cylinder that preceding magnetic pole (9) forms when rotating with the axis is the preceding surfaces of revolution (11); Back magnetic pole (10) is when pivoting, and the face of cylinder of formation is the back surfaces of revolution (12).Between the preceding surfaces of revolution (11) and the back surfaces of revolution (12), one section space (13) is arranged.
Magnet exciting coil (3) is on field spool (14), magnet exciting coil (3) and field spool (14) are in the fore paw utmost point (6), in the semi-surrounding structure that the rear solid end utmost point (7) and yoke (8) are formed, between the field spool (14) and the fore paw utmost point (6), the rear solid end utmost point (7) and the yoke (8) gapped (15); Field spool (14) is fixed on the stator (2) by fixed support (16), so magnet exciting coil (3) and field spool (14) remain static.Also (13) pass the lead (17) that links to each other with magnet exciting coil (3) from the space, to introduce exciting current.
In the outer ring of rotor (1) stator (2) is arranged, formed stator (2) on the track ring (19) by being fixed in of silicon steel plate packing one-tenth due to tooth (18); Stator winding groove [21] is arranged between adjacent stator tooth (18); Stator winding (20) is arranged in the stator winding groove [21]; Between stator (2) and magnetic pole (9), (10) air gap [22] is arranged.
