  • Patent number: 10305405
    Abstract: A subtractor subtracts an angular speed correction amount from a rotational speed command to obtain a corrected rotational speed command. An adder adds a second-axis current correction value to a ?c-axis current to obtain a corrected second-axis current. An angular ripple extraction unit obtains, from a rotational angle on a mechanical angle of a synchronous motor, a rotational angle difference being a ripple component of the rotational angle. An nth-order component extraction unit extracts nth-order components of a fundamental frequency of the rotational angle from the rotational angle difference. A torque conversion unit obtains nth-order components of an estimated value of vibration torque. A correction amount calculation unit obtains the second-axis current correction value using the nth-order components.

  • Patent number: 10291162
    Abstract: This invention pertains to a solution to the parasitic problem of motor armature reaction/generator action in electric motors which causes undesired effects such as neutral plane shift and flux weakening. Prior art interventions such as interpoles and compensating windings add to complexity and cost of electric motors without satisfactorily solving the problematic issues. This invention pertains to a novel method of employing the same primary magnetic field multiple times—first to change electrical input power to mechanical output power and then to reconvert this same stored electromagnetic field energy back into electric energy for storage and reuse. The primary electromagnetic field energy is used a second time after it has been used to create the desired change in kinetic energy of the secondary magnetic field being acted upon when it is allowed to collapse back into electric storage as it would do naturally once the input current is removed.
