PURPOSE:To obtain two output by one motor without needing a mechanical slipping mechanism by loosely fitting the second rotor to a shaft of the first rotor with a magnet and separately turning the second rotor through the revolution of the first rotor. CONSTITUTION:One motor is formed in such a manner that the shaft 7 is mounted to the first rotor 9 with the permanent magnet 10, and a coil for generating a revolving magnetic field is held to the shaft 7 through a bearing 4. A stepped section 7a is shaped previously to the shaft 7, and the second rotor 11 is loosely fitted to the shaft 7 so as to contact with the stepped section 7a, and doubled as a magnetic circuit of the first rotor 9. When the coil is conducted and the first rotor 9 is turned in such constitution, the second rotor 11 is rotated separately by eddy-current torque, hysteresis torque or friction torque from the stepped section 7a, and torque generated can be adjusted by controlling contact pressure with the stepped section. |
