Stark Level 8 High Power Disc Brushless Stator Silicon Steel Core Motor Engine ModelFeatures:.Design Intention: This product is composed of 8 circuit boards and 8 coils, each coil corresponds to a cir more→cuit board, does not interfere with each other, and can be energized at the same time or a single coil. The circuit adopts a self-excited structure. Each coil is formed by winding two wires at the same time. The thick wire is the driving coil and the thin wire is the signal coil. When the magnet passes through the coil, the signal coil will generate an electromotive force voltage, the voltage will turn on the mos tube, supply power to the drive coil and generate a magnetic field, thereby

Report

Stark Brushless 220V AC Asynchronous Motor Model Motor High-tech ToyFeatures:.Original Design Intention: An asynchronous motor is a motor that uses alternating current to rotate, without carbon brushe more→s, no magnets, and generates an alternating magnetic field by alternating current. The alternating magnetic field causes the rotor to induce current, and the induced current generates an induced magnetic field. The internal and external magnetic fields interact to drive the rotor, and spin constantly..This product uses a fully transparent structure and uses a ring-shaped silicon steel sheet as the core. It has a novel shape and a sense of technology..Technical Points: Customized ultra-thin
