Description
Technical field
The utility model relates to motor and electric bicycle, is a kind of coreless disc type motor that can be used for electric bicycle specifically.
Background technology
Common motor all needs thick and heavy silicon steel sheet as iron core, and iron core is used in stator and the rotor and is twined by coil, thereby volume is big, Heavy Weight.Need the little lightweight place of volume especially to be not suitable at electric bicycle etc.Be because people by traditional motor production method institute obstacle, in order to reduce the leakage field of electromagnet as far as possible, surround with thick and heavy silicon steel sheet around coil, the volume of motor and deadweight are all sharply increased.For need alleviating the product of deadweight, this class of electric bicycle increased the burden of motor and power supply on the contrary.
Summary of the invention
The purpose of this utility model is to disclose a kind of coreless disc type motor, makes the volume and weight of motor all greatly reduce.
Described coreless disc type motor, it is characterized in that: this motor comprise be enclosed within on the same motor shaft, flat disk and rotor endcap, rotor, coil windings, the electromagnetic disc of arranged in co-axial alignment successively, the wherein nested installation of bearing that embeds by the center of rotor endcap, rotor, electromagnetic disc with motor shaft, as direct fastening being nested in outside the motor shaft of the centre bore of the coil windings of stator, described rotor endcap and rotor are fixed as one, and leave the gap between rotor, coil windings, the electromagnetic disc; Described rotor cover fixedly is equipped with equally distributed polylith magnet steel to the one side of coil windings.
Divide three laminations that three groups of coils are housed in the described coil windings, one group every layer coil is introduced by a lead respectively.
Each group shape of described three groups of coils is consistent with winding structure, and each group coil is made up of a plurality of axis small coil parallel with motor shaft, and the center of small coil is equidistant with the axle center of motor shaft respectively, and three groups of angular distances such as coil dislocation are arranged.
The lead of described introducing passes by motor shaft inside.
The outside of described rotor endcap is provided with the output shaft with the rotor endcap one, on output shaft with the coaxial power output gear that is provided with of output shaft.
Described power output gear and output shaft are one.
The utility model has been broken traditional design of electrical motor thought, with the tray type structure formation motor of brand-new open no iron core, has alleviated the weight and volume of motor greatly, simplifies the structure, and facts have proved feasible.Need the product of lower weight and volume that important meaning is arranged for electric bicycle and so on.
Description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is the structural representation of coil windings.
Among the figure: 1-output shaft, 2-bearing, 3-rotor endcap, 4-magnet steel, 5-rotor, 6-coil windings, 7-electromagnetic disc, 8-motor shaft, 9-power output gear.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified: coreless disc type motor as shown in fig. 1, comprise be enclosed within on the same motor shaft 8, flat disk and rotor endcap 3, rotor 5, coil windings 6, the electromagnetic disc 7 of arranged in co-axial alignment successively, the bearing 2 and motor shaft 8 nested installations that embed by the center of rotor endcap 3, rotor 5, electromagnetic disc 7 wherein, as direct fastening being nested in outside the motor shaft 8 of the centre bore of the coil windings 6 of stator, described rotor endcap 3 is fixed as one with rotor 5, leaves the gap between rotor 5, coil windings 6, the electromagnetic disc 7; The diameter of described rotor 5, coil windings 6 and electromagnetic disc 7 is suitable.Described rotor 5 fixedly is equipped with equally distributed polylith magnet steel 4 in the face of the one side of coil windings 6.Replacing electromagnet to save magnetic field with permanent magnet coil and iron core partly takes place, has also greatly reduced the weight and volume of complete machine.
As Fig. 2, divide three laminations that three groups of coils are housed in the described coil windings 6, one group every layer coil is introduced by a lead respectively.The lead of described introducing passes by motor shaft 8 inside.Coil is as stator, with the motor shaft relative fixed.
Each group shape of described three groups of coils is consistent with winding structure, and each group coil is made up of a plurality of axis small coil parallel with motor shaft, and the center of small coil is equidistant with the axle center of motor shaft respectively, and three groups of angular distances such as coil dislocation are arranged.The axis of coil is over against magnet steel 4 planes, and the back side faces electromagnetic disc 7, and the magnetic line of force at the back side is absorbed by electromagnetic disc 7, and the electromagnetic disc of little magnetic resistance can stop the magnetic line of force to leak and cause near metal parts generation eddy current effect.Electromagnetic disc 7 local magnetizeds have greatly strengthened coil magnetic field simultaneously.When three groups of coils input alternating current, being taken turns magnetized electromagnetic disc 7 by the part can be driven to rotate.
As shown in Figure 1, the outside of described rotor endcap 3 is provided with the output shaft 1 with rotor endcap 3 one, on output shaft 1 with the coaxial power output gear 9 that is provided with of output shaft.
A kind of scheme is that described power output gear 9 is one with output shaft 1.Also can nested gear so that make.
