20090085425 | Flat Spring and Voice Coil Motor using the same - A flat spring of a voice coil motor includes a fixing frame having a first connector, and an elastic arm. The elastic arm includes a main body, and a first curve portion. The first curve portion is arranged on one terminal end of the main body and connects with the first connector of the fixing frame, or is arranged on one terminal end of the main body, which extends to the fixing frame. | 04-02-2009 |
20100164321 | Electromagnetically-countered actuator systems and methods - The present invention generally relates to electric motor systems which minimize irradiation of harmful electromagnetic waves by various means. More particularly, the present invention relates to an electric motor system with one or more counter units which minimize the irradiation of such harmful waves by suppressing the harmful waves to their sources and/or by emitting counter electromagnetic waves capable of canceling a desired portion of the harmful waves. Such counter units may then be incorporated into various locations for opposing magnetic poles of basic rotor units and/or basic stator units of the system. The present invention also relates to various methods of minimizing irradiation of such harmful waves by various electric motor systems, various methods of suppressing the harmful waves toward their sources, and various methods of canceling such harmful waves by the counter waves. The present invention further relates to various processes for providing such electric motor systems, various processes for making such counter units for the suppressing and/or canceling, and various processes for incorporating such counter units into various locations of the systems. | 07-01-2010 |

20120228990 | Permanent Magnet Type Electrical Rotating Machine and Permanent Magnet Type Electrical Rotating Machine System for Vehicle - Provided is a permanent magnet type electrical rotating machine which realizes a rotor retaining structure for securely preventing the rotor before being coupled to a prime mover from moving in any of not only the axial and radial but also rotational (circumferential) directions, even in a case where it is a large capacity (with a large magnetic attractive force) permanent magnet type electrical rotating machine having an overhung rotor support structure. | 09-13-2012 |
20130076201 | DRUM MOTOR - A drum motor has a drum motor shell having a hollow space therein, a rotor and a stator, and bearing journals in the drum motor shell, the rotor and the stator being mechanically coupled to the drum motor shell and the bearing journals in such a way that relative rotation between the rotor and the stator causes relative rotation between the drum motor shell, and the bearing journals. The drum motor shell has at least one torque transfer section in which the outer surface of the drum motor shell is polygonal in cross-section. The sprocket has a polygonal, preferably hexagonal inner recess. | 03-28-2013 |
20150076960 | FERROFLUID MOTOR - A ferrofluid electric motor and methods are presented. A magnetic field is generated by an electromagnet, a flow of a ferrofluid is induced in response to the magnetic field, and a turbine is rotated by the flow of the ferrofluid. | 03-19-2015 |
20150123512 | GENERATOR RETAINING RING AND OTHER COMPONENT THERMAL DEGRADATION EVALUATION BY EDDY CURRENT NON-DESTRUCTIVE EXAMINATION - Eddy current non-destructive examination and evaluation of physical properties of a component, such as a generator retaining ring, after experiencing potentially degrading thermal exposure during any stage of manufacture, assembly and service use, is performed to determine whether it is acceptable for service use, requires further modification (e.g., additional heat treatment processing) or whether is permanently unsuitable for service. Eddy current test measurements are correlated with component temperature exposure (e.g., absolute temperature and/or cumulative time-temperature heat absorption) and cumulative alteration of the component physical properties, such as, among others, material yield strength (YS), toughness, and tensile ductility. Using the eddy current test measurements and reference data correlating electrical conductivity with ring material thermal exposure, the component's physical properties are evaluated to determine its serviceability. The testing can be performed in situ in the field, such as for evaluation of generator rings within field serviced generators. | 05-07-2015 |
