Features:
.Scalloped design, 3-coil design, excellent stability, explosive power and dynamic explosion, can be rotated 2000-3000 per minute, very violent
.Product transparent design, exposed operation, transparent acrylic cutting and polishing, principle display and look and feel are excellent, showing an unusual taste of a person
.The input voltage requirement of the product is small, and the voltage of 5V can be used. The mobile power supply can be activated by wearing the boosting line, and the product is already installed, no need to reassemble, and extremely
.Verifiable product principle: electromagnetic induction, mechanics, Hall sensor
.The product can be operated without a motor. Because the Hall sensor is used, the Hall sensor is a semiconductor sensor. Under the action of the Lorent magnetic force, the electron flow is cheaper to the side when passing through the Hall semiconductor, so that the sheet side A potential difference is generated above, which is called the Hall voltage.
.The Hall voltage changes with the change of the magnetic field. The stronger the magnetic field, the higher the voltage, the lower the magnetic field, the weaker the voltage, the smaller the Hall voltage, usually only a few millivolts, but after the amplifier in the integrated circuit, The voltage is placed enough to output a strong signal. In the motor, a rotating magnetic steel is used as a switch for controlling the magnetic flux. When the magnetic steel is similar to the Hall sensor, the Hall voltage is large and will remain open. If it is farther, it is off state, the Hall voltage will disappear, so that the change of the Hall integrated circuit voltage can indicate where the axis is. With this principle, the product can be controlled to rotate.
.The product is suitable for people over 8 years old.
.The product is suitable for teaching models, technology decoration, gift giving, DIY modification, etc.
