Abstract

The utility model relates to a single-phase controllable claw pole magneto synchro motor and belongs to the field of power setting technology, mainly comprising a rotor part equipping on the shaft of a casing component, two coils which are separately equipped in the inside of the casing component, an upper claw pole board component which is sleeved on the coils, a middle claw pole board and a lower claw pole board which are separately sleeved in the coils to form a motor stator part, a capacitance which is connected on the phase splitting wires of the coils, and a hot shrinkage tube which is equipped on the pins of the capacitance. The structure of the utility model is compact and rational, and because the coils are connected with a capacitance in series, two currents in the coils only have one phasic angle difference, providing a rotor directional rotary magnetic field. The motor magneto rotor generates the directional rotation under the action of the directional rotary magnetic field, making the motor increase the capacitance of the series capacitance (by 44 percents). The output moment of the alternator can be greatly lengthened one time, compared with the common motor. In addition, the moment variation of the motor is 5% in the high-temperature circumstance, which can make the motor work under high temperature normally.

Description

Single-phase controlled pawl pole permanent-magnet synchronous machine

Technical field:

The utility model relates to a kind of single-phase controlled pawl pole permanent-magnet synchronous machine, belongs to field of power equipment technology.

Background technology:

Before the utility model was made, in prior art, this kind permagnetic synchronous motor normally adopted a coiling.Because the motor coil skeleton is little, the line footpath is little, the number of turn is many, coil point of contact radius in winding process constantly increases, the suffered tension force of tangent line constantly changes, uneven tension force all can exert an influence to line footpath and winding arrangement, cause line segment resistance inequality and winding induction reactance inequality, especially at high temperature, the high temperature resistant property of complete machine and load-carrying ability are affected, can not carry out operate as normal.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of compact conformation is provided, rationally; Can make rotor under the effect of directed rotating magnetic field, produce directed rotation, can improve the starting torque of motor, and the single-phase controlled pawl pole permanent-magnet synchronous machine of long-term operate as normal at high temperature.

Main solution of the present utility model is achieved in that

The utility model adopts rotor part 6 to be installed on 4 of the case components, duplicate gear 10 is installed on 1 of the dewclaw pole plate assembly, gear shaft 11 is contained on dewclaw pole plate assembly 1 axle sleeve, cover plate assembly 9 is contained on the gear shaft 11, it is characterized in that in case component 4, installing respectively two coils 5, dewclaw pole plate assembly 1 is enclosed within on the coil 5, middle pole plate 2, bottom crown 3 are enclosed within respectively forms the motor stator parts in the coil 5, electric capacity 7 is connected on the branch phase line of two coils 5, and heat-shrink tube 8 is installed on the pin of electric capacity 7.

Compared with the prior art the utility model has the following advantages:

The utility model compact conformation, rationally; Owing on coil, be connected in series electric capacity, make that electric current just differs a phase angle in two coils, thereby formed a rotor orientation rotating magnetic field, the rotor of motor magneto produces directed the rotation under the effect of directed rotating magnetic field; Can make motor strengthen the capacitance (increasing by 44%) of serial connection electric capacity, can improve the motor output torque greatly and increase than common electric machine and be twice, and under hot environment, moment variations 5% can make its at high temperature long-term operate as normal.

Description of drawings:

Fig. 1 is the utility model structural representation;

Embodiment:

Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:

The utility model adopts 2 coils 5 is housed respectively in case component 4, dewclaw pole plate assembly 1 is enclosed within on the coil 5, and middle pole plate 2, bottom crown 3 are enclosed within respectively forms the motor stator parts in the coil 5.The pawl number of poles of the dewclaw pole plate in the dewclaw pole plate assembly 1, middle pole plate 2, bottom crown 3 adopts the 6-12 utmost point respectively.Rotor part 6 is installed on 4 of the case components, and duplicate gear 10 is installed on 1 of the dewclaw pole plate assembly.Gear shaft 11 is installed on dewclaw pole plate assembly 1 axle sleeve.Cover plate assembly 9 is enclosed within on gear shaft 11 and dewclaw pole plate assembly 1 axle sleeve.Cover plate assembly 9 is enclosed within on the axle of gear shaft 11 and dewclaw pole plate assembly 1.Electric capacity 7 series coils 5, and be connected on the branch phase line of two coil 5 assemblies, heat-shrink tube 8 is enclosed within on electric capacity 7 pins.Because electric current differs a phase angle in two coils, thereby has formed a rotor orientation rotating magnetic field, so, the rotor of motor magneto produces directed rotation under the effect of directed rotating magnetic field.
