The working principle of linear electric machinery is linear electric machinery going up from the structure not only is from what rotate to electric machinery evolves and come, its job principle also with rotate electric machinery is similar, follow the principle of a few basic electromagnetism that electric machinery learns. Linear electric machinery is dc permanent magnetism here example, show the main job principle of linear electric machinery. VLP0020-0160 is electric machinery of group of a news, going up somehow with linear electric machinery is consistent. Distinction depends on, phonic group electric machinery has a coil only, magnetic pole does not exceed 2 pairs commonly, be asked to move in the limits in a pair of magnetic pole only, also do not need commutation. Break through limitation of this kind of journey when need, need to have more magnetic pole surely, come with more coil relay, this is linear electric machinery. So phonic group electric machinery also is called without inverting linear electric machinery. ) next flat that pursueing denotive is a model are linear the structure of electric machinery. The part of the gray in the graph is motherboard, maize diamonds is piece permanent magnet, yellow and gray part comprised the stator of linear electric machinery. Photograph adjacent the polarity of two permanent magnet is contrary, so the in if pursue,distributinging place of lines of force is shown. Maize dot shows the cross section of the lead in secondary coil. The way that can see wire is basic and perpendicular the direction at lines of force, when electricity is carried in lead, can produce a power. By left hand formula can is informed, according to direction of the electric current in lead different, can make coil produces towards the left or rightward force. The thrust that this force makes linear electric machinery does linear exercise directly namely is linear the working principle of electric machinery. Majority of linear electric machinery is synchronism of dc permanent magnetism linear electric machinery. The linear electric machinery of other sort, if communicate permanent magnetism synchronism,linear electric machinery, pace receives response of linear electric machinery, communication linear electric machinery. The fundamental that these electric machinery work is similar. Be located in magnetic field to hold conductance put oneself in another's position mediumly, this conductor gets the action of force, the direction of force can decide by left hand formula. The size of force by below formulary and affirmatory: Winding form: Across covers kind, 3 coil combination takes a polar distance, dimensional utilization rate is high, mover is shorter. The both sides with invalid coil can be arranged outside magnetic field, can increase medicinal powder hot effect. Blame cover tile kind, 3 coil take 2 polar distance, use at big thrust electric machinery commonly, of coil shape craft is simple, but in the center of coil must leave a blank, magnetic field utilization rate is inferior. Linear to bringing core electric machinery needs to use the technology with alveolar disappear normally, inclined chamfer a method, still have even if use fractional chamfer, the whole multiple of stagger magnetic pole and core concerns. The working principle of linear electric machinery is one kind changes electric energy into sharp movement mechanical energy directly, and the gearing that does not need any intermediate changeover orgnaizations. It can regard as to rotate electric machinery presses radial sliver, exhibit plane and become, if pursue,１ place is shown. A side that evolve by stator and comes is called primary, a side that evolve by rotor and comes is called sub. When applying actually, will primary and sub make different length, journey range needs in order to assure in place inside primary with sub the coupling between keeps changeless. Linear electric machinery can be short first monitor is sub, also can be long primary short sub. Considering production cost, moving charge, all use commonly at present short first monitor is sub. The working principle of linear electromotor and rotate electromotor is similar. It is with linear induction motor exemple: When primary winding tells alternating current source, produce travelling wave magnetic field in air gap, sub and be expert at below cut of wave magnetic field, give the response electromotive force and produce electricity, the action of magnetic field photograph in this electric current and air gap produces electromagnetism thrust. If primary and fixed, sub linear exercise is done below thrust action; Conversely, primary do linear exercise. Graph the transition process of 1 linear electric machinery is linear the type selecting of electric machinery is linear the importance of electric machinery type selecting is linear the structure of electric machinery system and rotate the texture of electric machinery system differs somewhat. Rotate electric machinery often passes the rotational component translate into such as guide screw, leather belt annulus to move point-blank. And linear electric machinery uses direct drive technology, the function of linear electric machinery had conclusive effect. User of linear electric machinery often has to laden motion a series of requirement. Need us to choose an appropriate electric machinery for the client so. If the choice is undeserved, likely the requirement of short of client, perhaps cause cost to rise needlessly to the client. Not all traditional main transfer machinery can be replaced by linear electric machinery, if working status cannot develop the high speed property of linear electric machinery, it is unreasonable that this kind replaces a likelihood. Traditional whirl the normal play that electric machinery can assure power through decelerate orgnaization, and the abidance of system of linear electric machinery thrust and the biggest thrust are limitary, and cannot produce greater power through the means such as decelerate however. Become so when rate is very low, force also cannot greaten, so normal power cannot be come out by play. Additional to cost issue, the early days cost of linear electric machinery although lever of prep above silk, but when the application to high accuracy, of the filar lever of advanced course purchase cost to also can be compared tall, and right now filar staff system also needs a consideration install uniform encoding implement, the cost gap between so linear electric machinery and filar lever can become very small; In and the platform of filar lever drive still is existing be being used safeguard and wear away problem, the labour cost that brings from this and safeguard cost to also not allow small inspect, finally, of the manufacturing technology as linear electric machinery rise and the quantity is produced expand what change ceaselessly, its purchase cost also reducing ceaselessly. The use of linear electric machinery returns the requirement choice electric machinery according to the client to did not rotate at present electric machinery is extensive, the user that understands linear electric machinery still is not very much. When the user is wanting to use linear electric machinery, choose the ability of linear electric machinery without proper motion. Need us to help user choice according to the requirement of the user so. Because the user does not have the ability of the choice, so the user can provide their requirement only. Use an occasion according to linear electric machinery, these requirements often are: The journey, acceleration, top speed. Actually, our client won't give us these data. Because those who come out need to calculate when these data, the user often won't be calculated, perhaps calculate computational data is not accurate. With respect to need at that time we think the client understands, linear electric machinery needs to drive what kind of load, this load should do what kind of exercise. CNC Milling CNC Machining
