According to the stator & rotor that can be positioned and is used for the direct current brushless motor, when a stator and a rotor are laminated, front surfaces and back surfaces of the stator and the rotor can be better distinguished and are determined whether to be upside down in terms of direction, so that the stator and the rotor can be better laminated and a magnetic line is better conducted to improve efficiency of the motor.
Description
Technical field
The utility model relates to the improvement of dc brushless motor rotor, particularly a kind of orientable rotor for dc brushless motor.
Background technology
Dc brushless motor is comprised of motor body and driver, is a kind of typical electromechanical integrated product.Brushless electric machine refers to the motor of brushless and commutator (or collector ring), claims again commutatorless machine.
Rotor is that rotating part in motor (rotor) is iron core, has installed in the above the paired N utmost point, the magnet steel of the S utmost point; And fixing part is called stator.To install coil windings on stator, produce magnetic force after energising, quote the two like magnetic poles repel each other of magnetic pole, the principle that there is a natural attraction between the sexes.Rear generation electromagnetic torque carries out power conversion.
But present rotor sheet is easy to the positive and negative and direction of rotor is got wrong because the shape of its positive and negative is similar when mounted, causes operating efficiency low.
The utility model content
The utility model provides a kind of easy identification rotor double-edged orientable rotor for dc brushless motor.
For solving the problems of the technologies described above, the utility model is used for the orientable rotor of dc brushless motor, comprising: arbor is provided with first and indicates groove on described arbor; Rotor core, described rotor core are set in outside described arbor, described rotor core and the coaxial setting of described arbor; Magnet steel, described magnet steel is evenly distributed on the edge of described rotor core, and described magnet steel is divided into 5 to the utmost point, and the quantity of described magnet steel is 10; Stator core, described stator core is set in outside described rotor core, be provided with air gap between described stator core and described rotor core, described stator core and described rotor core and the coaxial setting of described arbor are provided with second and indicate groove in described stator core; Stator slot, described stator slot is evenly distributed on the inside edge of described stator core, and the quantity of described stator slot is 15.Described magnet steel is dull and stereotyped magnet steel.
The orientable rotor that the utility model is used for dc brushless motor is respectively equipped with the sign groove in arbor and stator core, every a slice subscript is shown that the groove aligning gets final product in the stack of rotor sheet.Whether the utility model is used for the orientable rotor of dc brushless motor and can better distinguishes the positive and negative of rotor and have the phenomenon that direction is put upside down to occur at the rotor additive process, it better is superimposed, better comes the conducting magnetic line of force to improve the efficient of motor.In addition, the orientable rotor that the utility model is used for dc brushless motor changes present (15 grooves, 5 pairs of utmost points) into original (12 grooves, 4 pairs of utmost points), simultaneously original tile-shaped magnet steel is changed into present dull and stereotyped magnet steel.Assembling and fixedly during magnet steel operation simple to operation, also reduced the assembly difficulty of rotor, also reduced cost, the failure rate of rotor simultaneously; And its torque pulsation is little, starts steadily, and the stationarity of electric current is good.The orientable rotor that the utility model is used for dc brushless motor has solved the problem that difficulty is large when the assembling magnet steel, matching requirements are high, also cost, failure rate and the torque pulsation of rotor can be reduced.
