Description
Technical field
The present invention is electronic, the dual-purpose brshless DC motor of generating relates to be a kind of do not have silicon steel sheet, no coil, non-carbonate electronic, dual-purpose direct current machine generates electricity.
Background technology
Present direct current machine all has silicon steel sheet, wire ring, carbon brush, in use, and carbon brush and commutator segment friction, be easy to generate spark, wearing and tearing easily, coil is embedded in the silicon steel sheet, machining process is required high, and coil in use is easy to generate short circuit and causes damaging.Because DC motor rotor or stator adopt silicon steel sheet to make usually, in use are easy to generate eddy-current heating, cause the direct current machine temperature rise to improve, have a strong impact on direct current machine operating efficiency and useful life.At present commercially available brshless DC motor needs complicated electronic device control circuit to be controlled could guarantee normal operation, and failure rate and spoilage are higher, the manufacturing cost height.
Summary of the invention
The objective of the invention is at above-mentioned weak point provide a kind of electronic, dual-purpose brshless DC motor generates electricity, the rotor of motor is provided with annular permanent magnet, motor stator is provided with some transducing sheets, iron loss reasonable in design, simple in structure, no, turn round during work steadily, long service life, processing technology is simple, low cost of manufacture, can do electronic, dual-purpose direct current machine generates electricity.
Electronic, the dual-purpose brshless DC motor of generating takes following scheme to realize: electronic, the dual-purpose brushless DC motor structure of generating is made of rotor, stator, motor housing, it is characterized in that rotor has armature spindle, and armature spindle is outside equipped with non-magnetism bush.Non-magnetism bush is outside equipped with annular permanent magnet, annular permanent magnet two magnetic poles are arranged on the annular permanent magnet both ends of the surface, be provided with the annular magnetic conduction sheet in the annular permanent magnet both ends of the surface, the annular magnetic conduction sheet that the annular permanent magnet magnetic line of force is provided with through the annular permanent magnet two ends forms magnetic circuit.Stator is arranged in the motor housing, and stator has some transducing sheets, and stator is fixed in the motor housing, places two annular magnetic conduction sheet inboards of rotor, and leaves magnetic gap, adopts lead to carry out serial or parallel connection between the transducing sheet and draws two electrodes.Mutual insulating between some transducing sheets of stator.On end cap, two end cap is separately fixed on the motor housing by bearing fixing at the armature spindle two ends.
Operation principle: electronic, the dual-purpose brshless DC motor of generating can be used as generator and motor respectively, when as the generator time spent, external power supply drives the rotor rotation by armature spindle, form rotating magnetic field, the transducing sheet is the perpendicular cuts magnetic line of force in magnetic field, produce magnetic field, produce electromotive force E simultaneously, draw electric energy by the lead on the transducing sheet; When as the motor time spent, external power when electric current flows through the transducing sheet, produces motive force from motor extraction electrode input DC power, promotes the rotor rotation.
Electronic, the generating dual-purpose brshless DC motor reasonable in design, compare with conventional electric generators, simple in structure, no silicon steel sheet, no coil, non-carbonate, thereby do not have iron loss, no consumable accessory, rotating speed is even during work, running steadily, temperature rise is low, increases the service life, and is in light weight, can save non-ferrous metal, processing technology is simple, and low cost of manufacture can substitute original DC motor, DC generator.
