| 20110286133 | Fault Clearing Method for Permanent Magnet Machines - A permanent magnet machine (PMM) has a kinetic portion electrically coupled to a power conversion portion. Motive power is provided to the kinetic portion by a torque applied to a motive shaft coupled to a prime mover, such as an aircraft engine or an automobile engine. Generated power is transmitted through a plurality of electrically isolated output feeder cables. When a fault is detected, a switch is opened stopping the flow of current through the feeder cable associated with the faulty circuit. The fault condition is then rendered safe while the prime mover may continue normal operation. | 11-24-2011 |
| 20110149445 | Fault Clearing for Permanent Magnet Machines - A permanent magnet machine (PMM) has a kinetic portion electrically coupled to a power conversion portion. Motive power is provided to the kinetic portion by a torque applied to a motive shaft coupled to a prime mover, such as an aircraft engine or an automobile engine. A sensor is effective to detect a fault condition in the kinetic portion. When a fault is detected, the sensor applies a voltage to a winding within the kinetic portion generating an opposing directional counter torque to the motive shaft. A combination of the torque and counter torque exceeds a fracture yield strength of the motive shaft. The fault condition is then rendered safe while the prime mover may continue normal operation. | 06-23-2011 |
