Abstract
The utility model relates to the technical field of motors, in particular to a structural improvement for a permanent magnetic DC/AC motor. Wherein, two rows of symmetric air holes are arranged on a stator, a centrifugal worm-wheel vane is mounted on a rotor. The rotor drives the worm-wheel vane to rotate, so as to speed up air flowing and take away any heat generated on the rotor. The motor is to be used on an electric screwdriver, can efficiently drop the temperature at casing of the electric screwdriver, so that the casing will maintain a low temperature, and is comfortable to hold.
Description
Technical field:
The utility model relates to the motor technologies field, refers in particular to the structural improvement of a kind of permanent magnetism direct current, alternating current motor.
Background technology:
There is certain pure resistance value in the winding of permanent magnetism direct current, alternating current motor upper rotor part, motor is when work, current loss is just arranged on the winding, make rotor heating, see shown in the accompanying drawing 1, there is not steam vent on present permanent magnetism direct current, the stator 1 of alternating current motor, circulation of air path between stator 1 and the rotor 2 is very narrow, rate of air circulation is very little, the heat that just can not in time rotor 2 be produced during motor operations is taken away, cause heat accumulation on stator 1, make current loss bigger than normal, influence the useful life of motor.Particularly when permanent magnetism direct current, alternating current motor were used on the electric screw driver, because its heat can not in time scatter, heat passed on the electric screw driver shell, made the shell heating, and it is appropriate poor to hold.
The utility model content:
The purpose of this utility model is to provide a kind of simple in structure, permanent magnetism direct current of good heat dissipation effect, the structural improvement of alternating current motor at the deficiencies in the prior art, it can be used on the electric screw driver, it can in time be drained the heat on the electric screw driver, its skin temperature is obviously descended, and it is appropriate good to hold.
For achieving the above object, the utility model is achieved through the following technical solutions: it comprises rotor, stator, forms two steam vents on the described stator, and a fan blade is installed on the rotor.
The utility model is the pore that has two row's symmetries on stator, and a centrifugal turbine fan blade is installed on the rotor, when motor operations, rotor drives the turbine fan blade and rotates, the rotation of turbine fan blade makes air form one air-flow between two steam vents, quicken circulation of air, air-flow is in time taken away the heat that produces on the rotor, make rotor remain on a lower temperature, lifted from the useful life of motor, this motor is used for electric screw driver, and temperature that can more effective reduction electric screw driver shell makes it hold appropriateness and improves.
Description of drawings:
Accompanying drawing 1 is the permanent magnetism direct current of prior art, the exploded perspective view of alternating current motor
Accompanying drawing 2 is an exploded perspective view of the present utility model
Embodiment:
Embodiment sees accompanying drawing 2, it is the pore 3 that has two row's symmetries on stator 1, a centrifugal turbine fan blade 4 is installed on rotor 2 simultaneously, when motor operations, rotor 2 drives turbine fan blade 4 and rotates, and adds the circulation of air in the speed motor, the rotation of turbine fan blade makes air form one air-flow 3 of two steam vents, this air-flow is in time taken away the heat that winding on the rotor 2 produces, and discharges from pore 3, thereby makes rotor 2 remain on a lower temperature.This motor is used for electric screw driver, temperature that can more effective reduction electric screw driver shell, and it is better to make it hold appropriateness, makes electric screw driver after working long hours, and its shell still remains on a lower temperature, the too high phenomenon of temperature rise can not occur.
It only is preferred embodiment of the present utility model that above institute is chatted, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or decorate, is included in the utility model claim.
