Abstract
The utility model discloses a DC motor, comprising a casing (1), a plurality of stator coils (2) and rotor coils (3), which is characterized in that: the casing (1) is arranged at the inner center, the stator coils (2) are arranged annularly outside the casing, and the rotor coils (3) are annularly arranged outside the rotator coil (2), the stator coils (2) and the rotor coils (3) are wound around respective columns (4) and the quantity of the rotor coils (3) is one third of the that of rotator coils (2). The DC motor has the advantages that since an external rotor motor is adopted, the force arm is large and less electricity is consumed; the wire coil is wound on the wire column and the number of the coils can be increased or decreased at will; when the quantity of the wire coils is increased, the motor diameter can be enlarged and thus the current is changed.
Description
Affiliated technical field
The utility model relates to a kind of motor, is meant a kind of direct current machine that is applicable to flying saucer power especially.
Background technology
At present, prior motor is to produce rotating magnetic field by coil, thereby makes the motor rotation.Because coil is in wire casing, the number of turn is fixed, and can not arbitrarily increase, and causes power consumption big, and it is large diameter not to be easy to do, and more is not suitable for the power of flying saucer.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency of prior art, and a kind of direct current machine that is applicable to flying saucer power is provided, and its power consumption is few, and motor diameter is big.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: the utility model includes: housing, stator coil, rotor coil, it is characterized in that: housing is positioned at the center, its outer ring is provided with stator coil, the outer ring of stator coil is provided with rotor coil, stator coil, rotor coil all are wrapped on separately the terminal, and the quantity of rotor coil is 1/3rd of stator coil.
The utility model is taked technique scheme, has following beneficial effect: the utility model is owing to be external rotor electric machine, and the arm of force is big, power saving.Coil is wrapped on the terminal, can increase or reduce the number of turn arbitrarily, thereby changes electric current.The quantity that increases coil can the expanded motor diameter, and motor diameter can be by several meters to tens meters.The utility model power consumption is few, and several kilowatts current of electric can design in the milliampere level.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated.
Fig. 1 is the utility model structure diagram.
Mark among the figure: 1-housing, 2-stator coil, 3-rotor coil, 4-terminal
Embodiment
As seen from Figure 1, the utility model includes: housing 1, stator coil 2, rotor coil 3, housing 1 is positioned at the center, its outer ring is provided with stator coil 2, the outer ring of stator coil 2 is provided with rotor coil 3, stator coil 2, rotor coil 3 all are wrapped on separately the terminal 4, and the quantity of rotor coil 3 is 1/3rd of stator coil 2.Its operation principle is: stator coil and rotor coil energising back produce magnetic field, are outward the N utmost point, and interior is the S utmost point, makes two pairs of coils attract each other.Rotor coil is switched on all the time.After a pair of stator coil energising, produce magnetic field, make rotor coil be attracted; After its outage, adjacent another produces magnetic field after stator coil is switched on, and makes rotor coil be attracted over; So go round and begin again, make motor rotate.
Claims (1)
