The brush can slide up and down freely to adjust contact position for flexible experimental debugging.\u003c\/li\u003e\n\u003cli\u003eFor DC motor demonstration, it matches 4V to 6V DC power supply perfectly, with 3.5V starting voltage and 0.63A operating current. The armature runs smoothly and its rotating speed rises along with increased input voltage.\u003c\/li\u003e\n\u003cli\u003eDual functional design realizes electric drive operation and manual power generation experiment in one device, stable operating parameters and obvious experimental effects, suitable for electromagnetic related principle research and demonstration work.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"BrightMinds","offers":[{"title":"Default Title","offer_id":47690073571412,"sku":"SPH-B0H2967CHB","price":229.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0655\/3590\/1780\/files\/41gc7iRahuL._AC_SL1500.jpg?v=1789644902","url":"https:\/\/learnbrightminds.com\/products\/b0h2967chb","provider":"BrightMinds","version":"1.0","type":"link"}
