在速度方面直线电机具有相当大的优势。直线电机的速度为300m/min；加速度为10g。滚珠丝杠的速度为120 m/min；加速度为1.5g。从速度和加速度的对比上直线电机具有相当大的优势，而且直线电机在成功解决发热问题后速度还会进一步提高，而“旋转伺服电机+滚珠丝杠”在速度上却受到了较多限制很难再有所提高。从动态响应来讲直线电机因运动惯量和间隙以及机构复杂性等问题而占有优势。

Linear motor has considerable advantages in speed. The speed of linear motor is 300m/min; The acceleration is 10g. The speed of ball screw is 120 m/min; The acceleration is 1.5g. From the comparison of speed and acceleration, linear motor has considerable advantages, and the speed of linear motor will be further improved after successfully solving the heating problem, while the speed of "rotary servo motor+ball screw" is subject to more restrictions and is difficult to improve. In terms of the dynamic response, linear motor has advantages because of the inertia, clearance and complexity of the mechanism.

在速度控制方面，直线电机响应更快，调速范围更宽，达1:10000，可以在启动瞬间达到高转速，而且在高速运行时能迅速停止。

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

2、精度

2. Precision

精度方面直线电机因传动机构简单减少了插补滞后的问题，定位精度、重现精度和精度通过位置检测反馈控制都会较“旋转伺服电机+滚珠丝杠”高，且容易实现。

In terms of accuracy, the linear motor reduces the problem of interpolation lag due to its simple transmission mechanism. The positioning accuracy, reproduction accuracy and accuracy are all higher than "rotary servo motor+ball screw" through position detection feedback control, and are easy to achieve.

直线电机定位精度可达0.1μm。“旋转伺服电机+滚珠丝杠”的精度高为2~5μm。

The positioning accuracy of linear motor can reach 0.1 μ m。 The accuracy of "rotary servo motor+ball screw" is 2-5 μ m。

3、能耗

3. Energy consumption

“旋转伺服电机+滚珠丝杠”属于增力型传动部件。在提供相同转矩时，直线电机消耗的能源约比“旋转伺服电机+滚珠丝杠”多一倍以上。而且直线电机的可靠性受控制系统稳定性的影响，且对周边环境有较大影响，因此一定要采取的隔磁和防护措施以隔断磁场对滚动导轨的影响和对铣屑磁尘的吸附。

"Rotary servo motor+ball screw" belongs to energy-saving and force increasing transmission parts. When providing the same torque, the energy consumption of the linear motor is more than twice that of the "rotary servo motor+ball screw". Moreover, 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, magnetic isolation and protection measures must be taken to isolate the impact of magnetic field on the rolling guide and the absorption of magnetic dust from milling chips.

4、噪音

4. Noise

直线电机噪音小，因为直线电机不存在离心力的约束，运动时无机械接触，也就无摩擦和噪声。传动零部件没有磨损，可大大减小机械损耗，避免拖缆、钢索、齿轮与皮带轮等所造成的噪声，从而提高整体效率；

The linear motor has low noise, because the linear motor does not have the constraint of centrifugal force, and there is no mechanical contact when moving, so there is no friction and noise. The transmission parts are not worn, which can greatly reduce the mechanical loss and avoid the noise caused by towing cables, steel cables, gears and pulleys, so as to improve the overall efficiency;

滚珠丝杠经过长时间的使用，滚珠表面出现了剥落，或者是切削受力面的滚珠丝杆轴出现问题，间接影响了滚珠的运行轨道，造成了螺母和轴之间相互的摩擦造成了振动，以致发出的噪音过大；

After the ball screw has been used for a long time, the surface of the ball has peeled off, or the ball screw shaft on the cutting force surface has a problem, which indirectly affects the running track of the ball, causing the friction between the nut and the shaft to cause vibration, resulting in excessive noise;

5、行程

5. Travel

直线电机理论上可以做到无限行程；

Linear motor can achieve unlimited travel theoretically;

滚珠丝杆的螺母运转到有效行程之后，依然是可以进行适当的旋转，但是正常情况下，是不能旋转过度的，不然就会伤害到滚珠丝杆，导致滚珠颗粒和螺母的大量脱落，因而，一般是不建议运转的时候过量前进的。

After the nut of the ball screw runs to the effective stroke, it can still rotate properly, but under normal circumstances, it cannot rotate excessively, otherwise it will damage the ball screw, causing a large number of ball particles and nuts to fall off. Therefore, it is generally not recommended to move forward excessively when running.
