PURPOSE:To obtain a brushless DC motor by forming a cylindrical coil of a stator in a structure that windings are wound back and forth between both axial ends in a circle of circumferential direction of the coil and associating it with a rotor magnet. CONSTITUTION:Parallel wires 4 formed of insulated square wires in a plate shape are wound on a core 5 to form a coil inner layer 2b, the wires 4 are wound reversely on the outside to form a coil outer layer 2a, they are engaged and connected at the end, thereby forming a cylindrical coil 2. A motor is formed in combination with a rotor which is composed of rotor magnets 3 magnetized at N- and S-poles by securing to the inside of the stator yoke 1, the coil 2 is divided into equal segments, which are connected to be sequentially excited at the coil, thereby rotating the coil. Therefore, the motor is brushless in a slender shape, thereby reducing the inertia moment. |
