線性電動(dòng)機(jī)，也稱為線性電動(dòng)機(jī)，是制造公司在各個(gè)領(lǐng)域中常用的一種機(jī)械設(shè)備。 通過(guò)將其安裝在生產(chǎn)設(shè)備上，可以為企業(yè)的生產(chǎn)線提供高速自動(dòng)直線運(yùn)動(dòng)，可以有效地提高企業(yè)的生產(chǎn)能力。 作為產(chǎn)品，直線電機(jī)具有許多優(yōu)勢(shì)  以下是導(dǎo)軌絲杠和直線電機(jī)的主要特征之間的一些比較：

Linear motor, also known as linear motor, is a kind of mechanical equipment commonly used by manufacturing companies in various fields. By installing it on the production equipment, it can provide high-speed automatic linear motion for the production line of the enterprise, and can effectively improve the production capacity of the enterprise. As a product, linear motor has many advantages. The following are some comparisons between the main features of guide screw and linear motor:

1，速度

1. Speed

直線電動(dòng)機(jī)在速度方面具有相當(dāng)大的優(yōu)勢(shì)。 直線電機(jī)的速度為300m / min; 加速度是10克。 滾珠絲杠的速度為120 m / min，加速度為1.5 g。 線性電動(dòng)機(jī)與速度和加速度相比具有相當(dāng)大的優(yōu)勢(shì)，并且在成功解決熱量問(wèn)題之后線性電動(dòng)機(jī)的速度進(jìn)一步提高，并且“旋轉(zhuǎn)伺服電動(dòng)機(jī)滾珠絲杠”在速度上更加困難。 然后改善。 從動(dòng)態(tài)響應(yīng)來(lái)看，線性電動(dòng)機(jī)由于諸如運(yùn)動(dòng)慣性和游隙以及機(jī)構(gòu)復(fù)雜性之類(lèi)的問(wèn)題而具有優(yōu)勢(shì)。

Linear motor has a considerable advantage in speed. The speed of the linear motor is 300m / min and the acceleration is 10g. The speed of the ball screw is 120 m / min and the acceleration is 1.5 G. Compared with speed and acceleration, linear motor has a considerable advantage, and after successfully solving the heat problem, the speed of linear motor is further improved, and the speed of "rotary servo motor ball screw" is more difficult. And then improve. From the dynamic response point of view, the linear motor has the absolute superiority because of the problems such as the motion inertia and clearance and the complexity of the mechanism.

在速度控制方面，直線電機(jī)響應(yīng)速度更快，速度范圍更廣， 高可達(dá)1：10000，可以在瞬間開(kāi)始時(shí)達(dá)到 大速度，并且可以快速停止。

In terms of speed control, the linear motor has faster response speed, wider speed range, up to 1:10000, and can achieve high speed at the instant start, and can stop quickly.

2，精度

2. Accuracy

在精度方面，由于傳動(dòng)機(jī)構(gòu)的原因，線性電動(dòng)機(jī)的插補(bǔ)磁滯簡(jiǎn)單降低。 通過(guò)位置檢測(cè)反饋控制，定位精度，再現(xiàn)精度和精度高于“旋轉(zhuǎn)伺服電機(jī)滾珠絲杠”，并且易于實(shí)現(xiàn)。

In terms of accuracy, the interpolation hysteresis of linear motor is reduced simply because of the transmission mechanism. Through the position detection feedback control, the positioning accuracy, reproduction accuracy and absolute accuracy are higher than "rotary servo motor ball screw", and are easy to realize.

直線電機(jī)的定位精度可以達(dá)到0.1μm。 “旋轉(zhuǎn)伺服電機(jī)滾珠絲杠”的精度為2?5μm。

The positioning accuracy of linear motor can reach 0.1 μ M. The accuracy of the ball screw of the rotary servo motor is 2 ~ 5 μ M.

3，能耗

3. Energy consumption

“旋轉(zhuǎn)伺服電機(jī)滾珠絲杠”是一種的增壓器傳動(dòng)裝置。 當(dāng)提供相同的轉(zhuǎn)矩時(shí)，線性電動(dòng)機(jī)消耗的能量大約是“旋轉(zhuǎn)伺服電動(dòng)機(jī)滾珠絲杠”的兩倍。 此外，線性電動(dòng)機(jī)的可靠性受控制系統(tǒng)的穩(wěn)定性的影響，并且對(duì)周?chē)h(huán)境具有很大的影響。 因此，必須采取有效的磁隔離和保護(hù)措施，以阻止磁場(chǎng)對(duì)滾動(dòng)導(dǎo)軌的影響和切削粉塵的吸附。

Rotary servo motor ball screw is a kind of energy-saving supercharger transmission device. When the same torque is provided, the energy consumption of linear motor is about twice that of "rotary servo motor ball screw". In addition, the reliability of the linear motor is affected by the stability of the control system, and has a great impact on the surrounding environment. Therefore, effective magnetic isolation and protection measures must be taken to prevent the influence of magnetic field on rolling guide and adsorption of cutting dust.

4，噪音

4. Noise

線性電動(dòng)機(jī)的噪音低，這是因?yàn)榫€性電動(dòng)機(jī)不受離心力的約束，在運(yùn)動(dòng)過(guò)程中沒(méi)有機(jī)械接觸，也沒(méi)有摩擦和噪聲。 傳動(dòng)部件不磨損，可以大大減少機(jī)械損耗，避免拖纜，電纜，齒輪，皮帶輪產(chǎn)生的噪音，從而提高了整體效率;

The noise of linear motor is low, because the linear motor is not constrained by centrifugal force, there is no mechanical contact, friction and noise in the process of motion. The transmission parts are not worn, which can greatly reduce the mechanical loss and avoid the noise generated by the streamer, cable, gear and pulley, so as to improve the overall efficiency;

長(zhǎng)時(shí)間使用后，滾珠絲杠已在滾珠表面上脫落，或者滾珠絲杠軸存在切割受力面的問(wèn)題，這間接影響了滾珠的運(yùn)行軌跡，從而導(dǎo)致滾珠之間的摩擦。 螺母和軸會(huì)引起振動(dòng)。 這樣噪音太大了;

After a long time of use, the ball screw has fallen off on the surface of the ball, or the ball screw shaft has the problem of cutting the force surface, which indirectly affects the running track of the ball, resulting in friction between the balls. Nuts and shafts can cause vibration. It's too noisy;

5，行程

5. Itinerary

直線電機(jī)理論上可以實(shí)現(xiàn)無(wú)限行程;

In theory, linear motor can realize infinite travel;

導(dǎo)軌絲杠的螺母運(yùn)行到有效行程后，仍可以正確旋轉(zhuǎn)，但在正常情況下，不能過(guò)度旋轉(zhuǎn)，否則會(huì)損壞滾珠絲杠，導(dǎo)致大量的滾珠顆粒和螺母掉落 關(guān)。 通常不建議在運(yùn)行時(shí)繼續(xù)操作。

After the nut of guide screw runs to the effective stroke, it can still rotate correctly. However, under normal conditions, excessive rotation is not allowed. Otherwise, the ball screw will be damaged and a large number of ball particles and nuts will fall off. It is generally not recommended to continue at run time.
