[Know-how and its disadvantages] μ As shown in Figure 10, the 'outer rotor type brushless motor is a cylindrical outer rotor (71) provided with a permanent magnet (70) and covered with an exciting coil ( 72) and the outer edge of the cylindrical inner stator (74) of the inner stator roller iron (73), and a rotating shaft (75) is fixed at the center of one end of the outer rotor (71), and this rotating shaft (75) penetrates into the inner stator The central hole (76) of (74) allows the outer rotor (71) to rotate relative to the inner stator (74). When energized, the outer rotor (71) rotates around the inner stator (74) to output the required torque (Torgue) to the outside. Since the outer rotor (71) must rotate around the outer edge of the inner stator (74), only one end of the two ends of the outer rotor (71) is usually supported by the cylinder end surface (71a), and the other end The opening (71b) must be formed and be floating. When the excitation coil (72) of the inner stator (74) is energized, the interaction between the electromagnetic field generated by the inner coil (72) and the permanent magnetic field of the permanent magnet (70) of the outer rotor (71) will cause interaction of attraction and repulsion. The vibration of the outer rotor (71) is caused by the interaction between the two types of attraction and repulsion, and the vibration is induced by the phenomenon of vibration. The higher the centrifugal force when the speed is more south, or the stronger the magnetic field, the more serious the vibration and vibration problems mentioned above will be. Because of this problem, since the beginning of the outer rotor motor, it has been impossible to produce high horsepower and high 3 (please read the note on the back before filling this page)
