Description
Technical field
The present invention relates to a kind of motor technology, is related specifically to a kind of robot with miniature Non-iron core motor.
Background technology
Rare earth permanent magnetic non-iron-core motor is a kind of new special motor for representing electromechanics trade future thrust, using nothing
Iron core, it is brushless, without magnetic damping, rare earth permanent magnet generation technology, change conventional motors and use silicon steel sheet and winding stator structure, tie
The electronic intelligence converter technique of independent research is closed, electric system efficiency is brought up to more than 95%.Rare earth permanent magnetic non-iron-core motor
It is a great innovation, technically realizes " three is big " breakthrough, first, compared with conventional radial magnetic field structure designs, employ axle
Designed to magnetic field structure, increase substantially power density and torque volume ratio.Second, using novel winding technique, high voltage precision pressure
Type casting moulding and high polymer material, effectively reduce winding copper loss.Third, eliminated without using silicon steel sheet as stator and rotor core material
Magnetic damping and iron loss, reduce driving power, reduce iron loss pyrotoxin.
Rare earth permanent magnetic non-iron-core motor is a kind of completely new product, and market is among cultivation, and therefore, it is promoting and answered
Many difficulties and problems with aspect also be present：It is that social awareness is not high first.Most of users do not know about to the technology, to production
Operation principle, application effect, the reliability of product are also held the suspicious attitude.Next to that standard criterion lags.China is in magneto side
The standard in face is very deficient, is even more blank in terms of rare earth permanent magnetic non-iron-core motor, has had a strong impact on the product choosing of the type motor
Type, Performance Evaluation, quality testing etc., constrain the popularization and application of product.It is that industrialization level need to be improved again.At present,
Low power rare earth permanent magnetic non-iron-core motor has been produced in batches, is obtained in terms of small-size wind power-generating, diesel generation, electric tool
Promote the use of.But in, on heavy-duty motor also in demonstration phase.Policy Encouraging is a lack of in addition.Energy-saving efficient motor
The market obstacles such as initial cost height, information asymmetry be present, it is necessary to which country, which puts into effect related excitation policy, prizes market, cultivation production
Industry.
In summary, although rare earth permanent magnetic non-iron-core motor is a kind of new spy for representing electromechanics trade future thrust
Kind of motor, and there is very considerable economic benefit and social benefit, but due to presence because employing new technology, new technology, green wood
Market startup, the high Cost Problems of Industry Cultivation are influenceed caused by material, thus policy dependence is strong, the process of the popularization is not enough managed
Think.Obviously, if the motor released can be walked " prizing market with price, breed industry with market " using low cost as point of penetration
Road, then either for problem solve or for quickening show the economic benefit and social benefit of iron-core less motor for
All it is vital.
At present, a kind of collection magneto has solved above mentioned problem.
Collection magneto includes magnetic tent and coil, and the magnetic tent is made up of two parts permanent magnets, a part of permanent magnets N levels
All towards in magnetic tent, another part permanent magnets S levels are all towards in magnetic tent；The iron-less core coil is placed in footpath by rotating shaft
Into the magnetic tent in magnetic field, rotating shaft is in the interval of two parts permanent magnets.Wherein, when magnetic tent as stator, coil as rotor
When, magnetic tent can use box-shaped；When magnetic tent as rotor, coil as stator when, magnetic tent can use tubular.
Collect the invention main points of magneto：Using the magnetic tent internal coil in radially magnetic field, so as to realize motor-field solid
Change, making motor coil, often degree, every circle are all immersed in " even strong " magnetic field in 360 ° of rotations, then utilize radially magnetic field
Magnetic tent internal coil, imposes on dispatch from foreign news agency or external force causes magnetic tent, coil to rely on rotating shaft to produce relative motion and output of doing work or generate electricity.
It can make that product structure is simpler, and production cost is less expensive using air core coil；Can be solved at one stroke using ironcore choke
High-efficiency electric motor is difficult to the bottleneck problem minimized, Large Efficient electric motor structure complicates.
The permanent magnet that collection magneto is related to is generally neodymium iron boron, ferrite, glue magnetic material, and coil adopts known enamel-covered wire.
It is well known that graphene is the nano material that known world is most thin, most hard, its intensity more taller than steel 200
Times；The resistivity of graphene about 10-8Ω m, it is also smaller than copper or silver, it is the minimum material of world resistivity.Because of its resistivity
Extremely low, the speed of electron transfer is exceedingly fast, therefore is expected to can be used to develop lighter and handier motor.
Robot (Robot) is the automatic installations for performing work.The concept of robot has gradually been become in the world
It is near consistent.In general, people can receive this saying, i.e. robot is each to realize by self power and control ability
A kind of machine of kind function.
Robot is typically made up of executing agency, drive device, detection means and control system and complicated machinery etc..Driving
Device is the mechanism for driving executing agency to move, and the command signal sent according to control system, makes machine by means of dynamical element
People is acted.What it was inputted is electric signal, and output is line, angular displacement.The drive device that robot uses is mainly electricity
Force driving device, such as stepper motor, servomotor, also have in addition using the drive device such as hydraulic pressure, pneumatic.
Obviously, not only or will be in iron-core-free collection magnetic if graphene technological development and applied to iron-core-free collection magneto
Motor and its association area trigger revolutionary breakthrough, and may further result in graphene iron-core-free Miniature collecting magneto in robot
Extensive use in terms of drive device, and drive more than hundred million yuan of new industry chain of value.
