Its speed is not affected by the size of the load, unlike ordinary motor, when the load increases will appear when the speed of\u003cbr\u003e  the situation, the use of stepper motor speed and location are strict requirements.\u003cbr\u003e- Easy to control. Stepper motor is \"step\" as a unit of rotation, the digital features more obvious.\u003cbr\u003e- The whole structure is simple. The traditional mechanical speed and position control structure is more complex, difficult to adjust, the use of stepper\u003cbr\u003e   motor, making the whole structure becomes simple and compact. The speed motor converts the speed into a voltage and passes it to the input as a\u003cbr\u003e   feedback signal. The speed motor is a kind of auxiliary motor. The speed motor is installed at the end of the ordinary DC motor. The voltage\u003cbr\u003e   generated by the speed measuring motor is fed back to the DC power supply to achieve the purpose of controlling the DC motor speed.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"font-size:16px;\"\u003e\u003cstrong\u003ePackage Included:\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"font-size:14px;\"\u003e1 x 42 Stepper Motor (With 300mm Screw)\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cdiv style=\"text-align: center;\"\u003e\n\u003cimg alt=\"\" src=\"http:\/\/img.banggood.com\/images\/oaupload\/banggood\/images\/E1\/80\/56ca6e73-a32b-4d4c-8521-2f87ec3b40fc.jpg\" style=\"width:600px;\"\u003e\u003cbr\u003e\u003cbr\u003e\u003cdiv style=\"text-align: center;\"\u003e\n\u003cimg alt=\"\" src=\"http:\/\/img.banggood.com\/images\/oaupload\/banggood\/images\/0C\/51\/05a80c33-eaf4-4699-8bea-bc02a8e649d9.JPG\" style=\"width:600px;\"\u003e\u003cbr\u003e\u003cbr\u003e\u003cdiv style=\"text-align: center;\"\u003e\n\u003cimg alt=\"\" src=\"http:\/\/img.banggood.com\/images\/oaupload\/banggood\/images\/16\/95\/c40aedd3-e612-4c8f-87c1-a37377aed2ca.JPG\" style=\"width:600px;\"\u003e\u003cbr\u003e\u003cbr\u003e\u003cdiv style=\"text-align: center;\"\u003e\n\u003cimg alt=\"\" src=\"http:\/\/img.banggood.com\/images\/oaupload\/banggood\/images\/06\/51\/80f6d565-8fea-47e9-8e66-9d708dfbacf0.JPG\" style=\"width:600px;\"\u003e\u003cbr\u003e\u003cbr\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"\" src=\"http:\/\/img.banggood.com\/images\/oaupload\/banggood\/images\/18\/AB\/a83dbc40-c9d2-446e-9d38-5d8f3c74d38a.jpg\" style=\"width:600px;\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Electronic Pro","offers":[{"title":"Default Title","offer_id":14138330710060,"sku":"1135609","price":1665.4,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2787\/9162\/products\/83ca183f-78bd-4eb2-ab37-c100863a1d2f.jpg?v=1587124878","url":"https:\/\/electronic-pro-south-africa.myshopify.com\/products\/300mm-lead-screw-42-stepper-motor-z-axis-12vdc-1-3a-for-3d-printer-cnc","provider":"Electronic Pro ","version":"1.0","type":"link"}
