This is the method that we use a single-phase induction motor, that is, the capacitor splits the phase and uses the capacitor voltage to lag the current by 90°, and we solve the power supply of Columbus's egg.\u003cbr\u003e\u003cbr\u003eThe Columbus Egg is an egg-shaped copper block. In the rotating magnetic field, the egg rotates on its long axis and eventually stands thanks to gyro effect.\u003cbr\u003e\u003cb\u003e\u003cbr\u003eTechnical Key Points:\u003c\/b\u003e\u003cbr\u003e- Custom silicon steel core\u003cbr\u003e- 3D printed winding skeleton\u003cbr\u003e- Transparent acrylic structure\u003cbr\u003e- Fine winding group\u003cbr\u003e- 35mm solid big copper ball\u003cbr\u003e\u003cb\u003e\u003cbr\u003eRead Before Purchasing:\u003c\/b\u003e\u003cbr\u003e- The power supply voltage and power of the product cannot be changed privately.\u003cbr\u003e- It is strictly forbidden to connect wires without authorization.\u003cbr\u003e- The product is made of acrylic, please do not expose it to the sun.\u003cbr\u003e- Acrylic is fragile in winter or when the temperature is low, please use it carefully.\u003cbr\u003e- It is strictly forbidden to touch the rotating motor by hand.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eUse Method:\u003c\/b\u003e\u003cbr\u003eAfter receiving the product, connect power cord to the product and turn the switch. It is not recommended to use more than 5 minutes each time, because the coil will heat up. It is recommended to stop for a period of time to cool down before running again.\u003cbr\u003e\u003cb\u003e\u003cbr\u003ePackage Included:\u003c\/b\u003e\u003cbr\u003e- 1 x Motor Model Kit\u003cbr\u003e\u003cb\u003e\u003cbr\u003e\u003cspan style=\"color: #ff0000;\"\u003eNote:\u003cbr\u003e- Aluminum egg is not included, for demonstration purpose only.\u003cbr\u003e- A aluminum ball is included.\u003c\/span\u003e\u003c\/b\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Thanksbuyer","offers":[{"title":"Default Title","offer_id":40826114965553,"sku":"70190","price":111.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0578\/4790\/6353\/files\/7077322457137_watermarked_0.jpg_0.png?v=1767930399","url":"https:\/\/www.thanksbuyer.com\/ja\/products\/tesla-columbus-egg-tool-induction-motor-model-kit-aluminum-ball-explaining-rotating-magnetic-field","provider":"Thanksbuyer Online,SDR Radio, Testers and Measurement devices, Astronomy products,  Audio Amplifer and Decoders","version":"1.0","type":"link"}
