Abstract
The invention discloses a birotor non-commutation permanent magnet DC power-saving motor. The main poles of the stator and rotor of the motor are permanent magnets. During no power, the pole core of the rotor enables a permanent magnetic field of an external magnetic pole face of the pole core of the rotor to be conducted to a pole shoe, and generates an action force on a permanent magnetic field of the stator, thereby generating kinetic energy output. When the poles are connected electrically, the permanent magnet pole of the rotor is deviated from the pole on an inner rotor, freely rotating in an external rotor, under the action of a repellent magnetic field generated at the bottom of the pole, and attracts a magnetic conduction core generating permanent magnet leakage to be deviated to the pole, thereby shielding the leakage flux of the pole and increasing the electromagnetic torque. The electromagnetic field of the pole shoe is enabled to act on the permanent magnet pole of the stator, thereby generating torque output. The motor just needs to carry out the connection or disconnection of power to achieve continuous rotation, saves the electric energy consumed by a commutation electromagnetic torque, increases the effective torque generated by the permanent magnet mutual effect, can make the most of and give full play to the inherent magnetic energy of the magnet, reduces the power charges of the electromagnetic torque, is simple in structure, and is low in manufacture cost.
Description
Technical field
The present invention relates to a kind of economize on electricity motor.
Background technology
According to application number 201210107691.6, publication number CN103368465A, it relates to stator and rotor magnetic pole is all
The economize on electricity motor of permanent magnet, invention entitled: the Patent Publication document of " a kind of DC economize on electricity motor not commutated " is weighed
Profit requires 1 record: " be inside and outside towards, rotor permanent magnet (12) end face that outer pole-face polarity is identical by least two pieces of magnetic pole strengths
Parallel, be symmetrically fixed in irony rotating shaft (11) recessed grain, it is characterized in that: the bottom plane (10) of electromagnetic pole iron core (7) is inhaled
Attached, be fixed on rotor permanent magnet (12) outer pole-face with its magnetic conduction, the other end pole shoe (8) then towards stator pole face, its pole
The inclination angle of boots is towards unanimously, by power supply with electromagnetic pole winding (7) by the electric slip ring installed in motor and electricity on-off system electricity
Connection, in pole shoe (8) front end when root (15) of half point shoe magnetic conduction tile (1), electricity on-off system is by power supply and electromagnetism
Pole winding (9) turns on, and makes pole shoe (8) produce and attracts, with stator, the electromagnetic field that pole permanent magnet magnetic pole-face (5) polarity is identical, when
When pole shoe (8) is in stator repeller permanent magnet magnetic pole-face (2) central magnetic field position, electricity on-off system is by power supply and electromagnetic pole
Winding (9) power-off." technical scheme, it will be argued that its technological deficiency is: on the rotor of this motor, electromagnetic pole iron core with forever
Magnet poles face magnetic conduction, transfers out fixing permanent magnetic field when without electricity, acts on magnetic pole of the stator by pole shoe and makes rotor generation turn
Square；Its winding energising time, pole shoe end just produce reverse electromagnetism the action of a magnetic field in magnetic pole of the stator, make rotor produce another turn
Square, thus form that permanent-magnet torque adds electromagnetic torque combine output, reach the purpose of economize on electricity.But, when the energising of its winding makes pole
While boots end produces opposing magnetic field, its iron core and permanent magnet magnetic pole-face magnetic conduction source just produce one and permanent magnetic field polarity phase
With electromagnetism magnetic field and bigger leakage magnetic flux can be formed, then cause the iron loss of electromagnetic pole to strengthen, winding current double, pole shoe pair
The magnetic force of magnetic pole of the stator weakens the torque with rotor and reduces, and makes the power consumption of this motor increase on the contrary.
Summary of the invention
The DC that never commutates for solution economize on electricity motor electromagnetic pole leakage magnetic flux is big, iron loss causes greatly its torque to reduce, electricity
Machine power consumption increase problem, more substantially effectively utilize permanent magnetic, make magneto further economize on electricity, the present invention
A kind of birotor is provided not commutate DC economize on electricity motor；This motor can eliminate that above-mentioned motor flux leakage is logical big, iron loss causes greatly
Electromagnetic torque reduce, power consumption increase problem, formed permanent-magnet torque add electromagnetic torque more effective kinetic energy output, can more enter
More electric energy is saved on one step ground
The present invention solves its technical problem and is adopted the technical scheme that: symmetrical fixing multipair intrados polarity on motor stator
On the contrary, tactic stator permanent magnet, at the stator permanent magnet inner arc magnetic pole to rotor permanent magnet outer magnetic pole face magnetic field suction
Fixing half point shoe magnetic conduction tile on face, the centre-to-centre spacing of the tip of tile to rotor is more than the centre-to-centre spacing of its root to rotor.?
On outer rotor, symmetrical fixing pole shoe is towards consistent electromagnetic pole, with outer rotor inner edge at same circumference bottom its arc electromagnetic pole
On, electromagnetic pole pole shoe rotates along stator permanent magnet inner arc magnetic pole strength；Polarity identical turning in symmetrical fixing outer magnetic pole face on internal rotor
Sub-permanent magnet, pole-face and conducting magnet core magnetic conduction in rotor permanent magnet body, fixing, conducting magnet core pole shoe outer rim and the external magnetic of rotor permanent magnet
Pole-face is on same circumference；Internal rotor is the most freely rotatable in outer rotor, bottom electromagnetic pole pole-face external with rotor permanent magnet and
Conducting magnet core pole shoe air gap excitation.By DC source with electromagnetic pole winding by electric slip ring, brush and relay Electricity Federation, at electromagnetism
When pole pole shoe is in half point shoe magnetic conduction tile root, DC source is turned on by relay with electromagnetic pole winding so that it is pole shoe produces
Power-off after the raw electromagnetic field identical with half point shoe magnetic conduction tile leakage field polarity.In outer rotor, the electromagnetism when relay power-off
Attracted magnetic force less than its attraction magnetic force, rotor faced by rotor permanent magnet outer magnetic pole by conducting magnet core bottom pole
Permanent magnet outer magnetic pole deflecting facet is to bottom electromagnetic pole；Produce bottom electromagnetic pole when power supply is led by relay with electromagnetic pole winding
Rotor permanent magnet outer magnetic pole face is repelled by raw magnetic field, bottom rotor permanent magnet deviation electromagnetic pole.The axis of internal rotor is pacified
Dress unilateral bearing, so that outer rotor surmounts internal rotor and rotates.
This beneficial effect of the invention is: just can make direct current permanent magnet motor continuous running without commutation, it is to avoid bigger leakage field
The motor electric charge that logical and iron loss causes increases and the problem of power factor decline.Can utilize more fully and play permanent magnet
Intrinsic magnetic energy effect, increase permanent magnetic field and interact the torque produced, reduce the electricity consuming electric charge of electromagnetic pole, then make this electricity
Function further saves electric energy, and simple in construction, low cost of manufacture.
