Description
The present invention relates to a kind of series brushless electric machine, belong to the electronic product field.
Application number 95115186.X discloses a kind of brush-less electrically exciting motor technology, this electric efficiency height, and applied widely, cost is low, but that some parts still can improve is perfect.
The objective of the invention is to overcome the prior art deficiency, and provide a kind of simple in structure, cost is low, reliable operation, and Maintenance free can be realized the series brushless electric machine of stepless time adjustment.
The present invention is achieved in that series brushless electric machine is on the brush-less electrically exciting motor basis, by changing a kind of New-type electric machine that the armature winding working method realizes.This motor is by motor body, and position detector, power controller are formed.Motor stator core 5 adopts the coiling tray type structure, the two sides fluting, and armature winding 3,6 is embedded in the groove respectively.The armature that has excitation function concurrently around but 3,6 adopt every mutually every groove way and double-layer winding configuration.Rotor 1,2 is multipole symmetrical pawl formula structure, is distributed in due to iron core 5 both sides, and the position detector of formation, power control is known configurations.
Accompanying drawing 1 is a series brushless electric machine bulk junction composition.
Accompanying drawing 2 is series brushless electric machine armature winding form figure.
Accompanying drawing 3 is the two-phase series connection armature converter circuit schematic diagram of the brushless brushless electric machine of series excitation.
7 is stator core among the figure, and 8 is the rotor axial region, and 9 is a line chart, and 10 is the A coil, and 11 is the groove position.
Below in conjunction with accompanying drawing to this bright being described in further detail: this series brushless electric machine is by motor body, and position detector, power control 10 are formed.Motor stator core 5 adopts the coiling tray type structure, the two sides fluting, and armature winding 3,6 is embedded in the groove respectively.In order to realize armature winding series excitation excitation, the armature winding 3,6 that has excitation function concurrently adopts every mutually every groove way and double-layer winding (as shown in Figure 2).Be an armature winding coiling of series brushless electric machine (4 pairs of pawl utmost point rotors) stator form, this phase winding has two windings to be respectively A and a winding in the every groove of this face of stator.After the A coil is switched on, the sense of current is an ecto-entad in a certain groove of stator, constitute clockwise exciting current simultaneously rotor is carried out excitation, when the rotor running, in the time of need commutating to this phase armature supply, A coil ripple turn-off and a coil by open-minded, the electric current in a coil makes with the sense of current of last same embedded coil realizes the change of current from inside to outside, and the exciting current that forms still is a clockwise direction.The series brushless electric machine armature around but can adopt heterogeneous structure, specifically depend on the needs.But but also parallel operation of polyphase windings tandem working, every phase change of current operation principle is same as above, and excitation electricity sulphur direction remains unchanged and realizes the armature change of current.Series brushless electric machine detects the rotor position by rotor-position sensor 4 exactly, and carries out the change of current at the power component that place, the position sensing of determining goes out signal control switch circuit by certain logical relation, realizes keeping the exciting current direction constant.And energising winding armature magnetic pad changes with rotor 1,2 rotation change, acts on mutually with rotor 1,2 magnetic potentials, and producing and promoting rotor 1,2 is multipole symmetrical pawl formula structure, is distributed in stator core 5 both sides, forms axial air-gap.The position detector, the power controller that constitute series brushless electric machine are known configurations.Motor change of current control circuit is a known circuits, and this motor adopts two-phase series connection armature converter circuit (as shown in Figure 3) commonly used.
The tandem brush motor is through using, and its performance is better than other motor, sees following table for details:

The present invention compared with prior art has the following advantages:
1. by the armature winding change of current 2 excitations, need not special Exciting Windings for Transverse Differential Protection, winding is concentrated, and the end is short, and the utilization rate of copper is high, and copper loss is few.
2. the magnetic field of rotor excitation back formation makes diversity claw magnetic pole be distributed in the stator both sides respectively, and leakage field is few.
3. stator core is the coiling tray type structure, and the silicon steel consumption is few, and volume is small and exquisite.
4. simple in structure, easily to make, cost is low, reliable operation, Maintenance free.
5. adopt the way and double-layer winding construction, the required switch element of the change of current is few, the circuit reliability height.
6. can realize stepless time adjustment.
