| A drive train is used at least including an input shaft and an output shaft. A clutch member is rotatable by a clutch shaft about an axis of rotation. The clutch shaft is supported for lateral movement along the axis of rotation to move the clutch member to cooperate with the drive train at a first lateral position to cause the output shaft to turn and to move the clutch member to a second lateral position to disengage the output shaft from rotation of the input shaft. A permanent magnet is supported by one end of the clutch shaft and arranged for receiving an external magnetic biasing force along the axis of rotation to selectively move the clutch member between the first and second lateral positions. A traveling shaft can be used to support a selected gear for movement by the permanent magnet to implement transmission and reversing configurations. | ||||||

| 139 | Magnetic induction coupler | US10431448 | 2003-05-08 | US20040130228A1 | 2004-07-08 | Huang-Tung Chang |
| A magnetic induction coupler mainly comprises an outer wheel having a conducting strip rotor attached on its inner wall and a magnet stand located within the outer wheel, both arranged coaxially on a shaft. A number of permanent magnets are arranged around the outer wall of the magnet stand to form a multipolar magnetic field. A number of conducting strips are circularly distributed on the conducting strip rotor and electrically connected. The rotational motion of the outer wheel is mechanically decoupled from the magnet stand by two sets of bearings. To achieve relative motion between the outer wheel and the magnet stand, a motor is used to drive the outer wheel. As the outer wheel rotates, an induction torque produced by an electric current induced in the conducting strip rotor drives the shaft to move accordingly. Further, the magnitude of the induction torque is proportional to the motor speed. | ||||||
