雙金屬熱過載繼電器
在雙金屬繼電器中，使用雙金屬片并將其放置在電路中，使電流流過它。
由于其特性，帶材會(huì)持續(xù)加熱。當(dāng)電流超過限制時(shí)，它會(huì)以如此大的方式加熱，從而斷開與輸出電源的接觸。
這是過載繼電器的傳統(tǒng)工作方式。過載繼電器就是在這個(gè)工作原理的基礎(chǔ)上建立的。
電子過載繼電器
在電子繼電器中，溫度傳感器和電流互感器位于電機(jī)電路中以檢測溫度和電流的升高。
B&R 7AI261.7傳感器用于感測溫度。由于使用了微處理器和傳感器，這種繼電器的傳感技術(shù)比傳統(tǒng)的雙金屬繼電器精確得多。
How much noise is tolerable in the application? If your application will be used in a factory largely away from people, noise may not be an issue. But if it will be used alongside humans for more than a brief amount of time, you may favor a quieter motor.
3. How much precision is required? When a robot is being used to move shelves in a warehouse, not much precision is required, whereas there is no room for error when one is filling prebions. Different motors provide precision in different ways, some with distinct disadvantages; it’s important to know which of these may be allowable for your product.
4. How much torque is necessary? Torque can be achieved at various speeds and with varying degrees of constancy. If you need high torque only at a particular speed, you may be able to sacrifice unnecessary torque capability for other motor features.
Now let’s review the three types of electric motors most often used to run applications on a typical jointed arm robot—DC, stepper, and servo—against these considerations.
