  • System and method for asynchronous permanent magnet motor operation
    Patent number: 9698714
    Abstract: A method for implementing asynchronous operation of a permanent magnet motor (PMM) by detecting asynchronous operation of the PMM and creating cyclic variations in the PMM output using the asynchronous operation of the PMM. In another embodiment, an apparatus that comprises a microcontroller that obtains computer executable instructions stored on a non-transitory medium that when executed by the microcontroller causes the apparatus to determine that a rotor shaft within a PMM is rotationally restricted and to vary a plurality of frequencies and a plurality of amplitude currents supplied to the monitor to produce a reverse impact on a downhole tool coupled to the PMM.
    Type: Grant
