Abstract
The invention provides a novel electric rotating device, an electric fan and an electric blower which use the rotating device, an electric blower which uses a novel motor without a rotating shaft , an electric propeller, a washing machine capable of directly rotating an internal cylinder, and an electric blower and pump in a round pipe duct. As the prior electric rotating device like the electric fan or blower generally has blades assembled on the output shaft of a motor and realizes blasting through the motor driving the blades to rotate, the motor has to be arranged at the center of the blades, thereby bringing about the problems that air flow is blocked by the motor and the blowing efficiency is low. In order to disuse the prior motor and reduce weight, the invention easily obtains a magnetomotive force and changes the magnetomotive force into a driving force through winding a coil on a ring body and assembling permanent magnets on the blades opposite to the inner circumferential part of the ring body.
Description
Technical field
The present invention relates to a kind of electric rotary body, this electric rotary body is wound with coil groups on cirque body, in addition, have permanent magnet at the end of the blade that is positioned at its relative position, thereby carry out rotatablely moving of blade efficiently, can easily obtain magnetomotive force.In more detail, the invention still further relates to such electric rotary body is installed in electric fan, electric blower and motor on the predetermined supporting mass.
Background technique
Existing electric fan because generally with blade installation on the output shaft of motor, thereby make the blade rotation realize air blast by motor, there be the mobile obstruction of motor, the shortcoming of air blast inefficiency of being subjected to of air so have at the central position of blade configuration motor.
Blow out by vane plate as a kind of heat that the motor that is positioned at the blade center is produced and to carry out improved fan, the spy opens and discloses following a kind of " fan " in flat 9-133092 number, and this fan comprises: a plurality of blades; The ring housing, it is above-mentioned a plurality of blade to be positioned at imaginary circles, spaced apart and be the state that general radial is extended along the circumferencial direction of above-mentioned imaginary circles from the center of imaginary circles, and under this state, be connected and be rotated, thereby make the rotation of above-mentioned blade integral ground with the peripheral part of above-mentioned each blade; Support mechanism, it supports according to the mode that the peripheral part that makes above-mentioned housing can move along the circumferencial direction of above-mentioned housing; Pedestal, it supports above-mentioned support mechanism; And driving mechanism, it is supported by said base on the outside radially of above-mentioned support mechanism, and above-mentioned housing is moved along its circumferencial direction.
Because said fans is arranged on motor in the pedestal, and by magnet being embedded housing with its rotor use as motor, so be a kind of the do not blow out air of heating and fan in light weight, easy to use owing to the heat of motor.
On the other hand, the same with fan, the blower fan that is installed on ceiling or sidewall has such structure, promptly disposes motor at central part, utilizes the driving force of motor to make to be installed in terminal plate etc. to be rotated.People are just developing on the one hand can seek miniaturization and and low consumption electrification, can change the standardized blower motor of realizing of rotational speed on the other hand from the low-speed range to the high-speed range arbitrarily yet now.
As such brushless motor, open in flat 11-136989 number the spy and to disclose " driving-controlling device of brushless motor and the electrical equipment that has used this device ", wherein, the driving-controlling device of this brushless motor comprises: permanent magnet rotor; A plurality of position detecting mechanisms, it detects the position of this permanent magnet rotor; The rotational speed arithmetical organ, it calculates the rotational speed of above-mentioned permanent magnet rotor; The multi phase stator winding; A plurality of switching elements, it is connected with above-mentioned each staor winding, is used for distinguishing according to the rules direction and order energising successively; Switch power, it gives the power supply of said stator winding by above-mentioned switching element by the said stator element; The switching element engaging means, it is corresponding with the state from the combination of the position probing output signal of above-mentioned position detecting mechanism, connects the switching element of pre-determined regulation, so that direction respectively according to the rules and order switch on for the said stator winding successively; The switching element release mechanism, it disconnects the switching element of this time connecting in the back at the appointed time; And carrying capacity decision mechanism, its rotational speed at above-mentioned permanent magnet rotor has become predetermined rotational speed N1 and has judged when following.And bracker fan, ceiling fan and industrial blower are provided as the electrical equipment that is mounted with this device.
