Abstract
The utility model relates to a brushless double-magnetic gap energy-saving dc motor. The inner and outer magnetic steel (3) (2) which are installed at the fly wheeled rotor and the middle stator coil unit (7) are gathered together to form two magnet gaps (8) (9). The motor is brushless, sparkless and easy to start with big dynamic force. The saving of energy is obvious and the manufacture is easy. The motor is suitable for not only general situation, but the special situation which is damp or flammable and explosive. It is widely used in electric power assisted bicycle, electric automobile and other machines which needs the electric force to be transformed into dynamic force. The rotating dynamic force is generated from the rotor shaft hole (4) with shaft. If bigger dynamic force is needed, it can be done by joining the long shaft and rotor shaft hole (4) in series.
Description
The utility model relates to the two magnetic gap energy saving dc motors of a kind of brushless, is the improvement to present DC motor.
Existing DC motor adopts brush to power to rotor coil, and electric energy conversion kinetic energy efficient is not high, and is easy to generate shortcoming such as spark damage commutator.
The purpose of this utility model is that a kind of above-mentioned shortcoming that overcomes will be provided, have brushless, no-spark, efficient energy-saving, the two magnetic gap energy saving dc motors of brushless in light weight, easily manufactured, that the life-span is long, not only be suitable for common occasion, but also be applicable to humidity, the abominable special occasions of inflammable and explosive environment, can be widely used in electric assisted bicycle, electric automobile and other need transfer electric power in the machinery of power to.
The two magnetic gap energy saving dc motors of brushless have been installed inside and outside magnet steel on the flywheel-type rotor, need not to the rotor power supply, and only need to have cancelled brush to the stator coil power supply, have save the rotor power supply, and are energy-conservation quite obvious.Because stator coil two ends correspondence position has been installed the inside and outside magnet steel of rotor, produces two magnetic gaps, starting is easy, power is big, and rotary power is from rotor axle sleeve axle output.Obtain bigger outputting power as need, the rotor axle sleeve that available major axis will many brushlesses pair magnetic gap energy saving dc motors is together in series and gets final product.
Further specify the structure and the operation principle of the two magnetic gap energy saving dc motors of brushless below in conjunction with accompanying drawing.
1. magnet steel in flywheel-type rotor 2. rotor outer steels 3. rotors
4. rotor axle sleeve 5. bearings 6. stators
7. magnetic gap 9. outer magnetic gaps in the sets of stator coils 8.
Only marked the inside and outside magnet steel of a pair of rotor (3) (2) in the accompanying drawing O-O cutaway view and corresponding one group of stator coil claims (7a), (7b), (7c) clockwise, all the other every pair inside and outside magnet steel of rotor (3) (2) and sets of stator coils (7) do not mark, but its state, in proper order identical.
Stator (6) is a garden shape, and stator coil is evenly installed at the edge, and per three stator coils are formed sets of stator coils (7), and same group of stator coil claims (7a), (7b), (7c) clockwise.(7a) in each sets of stator coils (7) is all in parallel, (7b) is all in parallel, (7c) is all in parallel.
Rotor outer steel (2) is evenly installed at flywheel-type rotor (1) proximal edge place, and all rotor outer steel (2) magnetic are towards interior polarity unanimity; The corresponding sets of stator coils (7) of each rotor outer steel (2); In the rotor outer steel (2) in correspondence is installed rotor magnet steel (3), (2) (3) magnetic opposite face polarity is inhaled mutually; Rotor outer steel (2) is sets of stator coils (7) with the centre of the interior magnet steel (3) of rotor, magnetic gap (8) and outer magnetic gap (9) in forming.Its running principle is the direct voltage that rotor coil is applied variable positive-negative polarity respectively, make (7) form the electromagnet of variable magnetic field polarity, form the situation of inhaling mutually or repelling each other by magnetic gap (8) (9) with rotor internal-external magnetic steel (3) (2), produce power, promote to fly rotatable rotor (1) and rotate.
When the logical positive electricity of stator coil (7a), (7b) logical negative electricity, (7c) outage, magnet steel (3) is subjected to (7a) and repels, is subjected to (7b) attraction, (2) (3) move on to (7b) from the correspondence position of (7a) correspondence position in rotor outer steel (2) and the rotor; Then (7a) outage, (7b) logical positive electricity, (7c) logical negative electricity, (2) (3) are subjected to not only that (7b) repels, is subjected to that (7c) attracts, (2) (3) but also move on to the correspondence position of (7c) from the correspondence position of (7b); Then (7b) outage, (7c) logical positive electricity, (7a) logical negative electricity, (2) (3) move on to the correspondence position of next group (7a) again from the correspondence position of (7c); By that analogy, Infinite Cyclic.Flywheel-type rotor (1) rotates, and its power is exported with axle by rotor axle sleeve (4).
The rotating speed control of the two magnetic gap energy saving dc motors of brushless can realize by control power supply switching frequency.
