Abstract
The utility model discloses a permanent-magnetic direct-current motor for a juicer, a cooking machine and a soymilk maker, comprising a motor case, a magnetic-steel stator, a rotor, a rotor shaft, a front end cover and a rear end cover, wherein the rotor is arranged in a bearing of the front end cover and the rear end cover of the motor case by the rotor shaft; the rear end of the rotor is provided with a temperature reducing fan and a commutator; and a middle plate connected with the rear end cover is provided with a carbon brush. The front end cover and the rear end cover of the motor case form a cross-shaped structure. The temperature-reducing fan also can be arranged on the rotor shaft outside the front-end case of the rotor. In the permanent-magnetic direct-current motor, the mode that the temperature reducing fan is arranged at the rear end of the rotor in the motor case or is arranged on the rotor shaft outside the front-end case of the rotor is adopted for radiating in the motor, so that the ventilation in the motor is good, the working temperature of a permanent magnetic direct-current motor is effectively reduced, the problem of poorer radiating function of the small-sized permanent magnetic direct-current motor for the juicer is solved and the normal use of the juicer is guaranteed.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
A kind of permanent magnet DC motor that is used for juice extractor, cooking machine and soy bean milk making machine; As depicted in figs. 1 and 2; Comprise motor case 1, magnet steel stator 2; Rotor 3, armature spindle 4 and front and rear cover 5 and 6, described rotor 3 are installed in through armature spindle 4 in the bearing 7 of motor case 1 front and rear cover 5 and 6, and cooling fan 8 and commutator 9 are equipped with in the rear end of described rotor 3; With on the intermediate plate 10 that rear end cap 6 is connected carbon brush 11 is housed, the front end housing 5 and the rear end cap 6 of said motor case 1 are " ten " font structure.
The utility model is used for the permanent magnet DC motor of juice extractor, cooking machine and soy bean milk making machine; Adopted the mode that cooling fan 8 is installed in the rear end of motor case 1 internal rotor 3; Motor internal is carried out radiating and cooling,, make the motor front and back unobstructed because the front end housing 5 of motor case 1 is " ten " font structure with rear end cap 6; Inner ventilation is good; Under the drive of rotor 3, the fan 8 of high speed rotating can be discharged the heat that produces behind the motor rotation outside the casing 1 effectively, plays good cooling effect behind the motor rotation.
Perhaps; The cooling fan 8 of the utility model permanent magnet DC motor is contained on rear end casing 1 armature spindle 4 outward of rotor 3 with another kind of form; The same negative pressure that can be produced through the fan 8 of rotation; Extract out rapidly from the heat that four indentation, there of motor case 1 " ten " word rear end cap 6 produce after with motor rotation, effectively dispel the heat and lower the temperature, keep the good operating condition of motor.
Above-mentioned execution mode is an instance of the utility model; Not enforcement and the interest field that is used for limiting the utility model; All equivalences of making according to the described content of the utility model patent protection scope change and modify, and all should be included in the utility model claim.
