Abstract:
A motor includes a shaft including upper and lower shaft members spaced axially away from each other. A shaft connecting member made of electrically insulating material is arranged axially between the upper and lower shaft members. The shaft connecting member is provided with fitting portions to which the upper and lower shaft members are to be fitted. While the upper and lower shaft members are secured to the shaft connecting member, the rotor magnet is integrally formed with the upper and lower shaft members and the shaft connecting member. With this configuration, an axial electric current is prevented from flowing through the shaft by the shaft connecting member.
