A sensorless motor drive apparatus and a method for protecting and controlling the same. The sensorless motor drive apparatus includes a unit for determining the presence or absence of a position estimation error of a rotor contained in a motor using a current value applied to the motor and a position estimation angle of the rotor. Therefore, the sensorless motor drive apparatus determines the presence or absence of the position estimation error of the rotor without using a sensor, so that it reduces production costs, prevents the motor from generating a faulty operation, and prevents a compressor including the motor from being damaged.

The present invention includes compositions, devices and methods for filling structures of high aspect ratio elements for growth amplification and device fabrication. A method includes a method of filling a structure comprising the steps of providing one or more structures, each structure having a plurality of high aspect ratio elements, wherein the aspect ratio is at least 5; and coating the plurality of high aspect ratio elements with at least one solidifying material produced by a form of chemical vapor deposition thereby forming a structured-film. Compositions of the present invention are solid formed structures that are less fragile, do not require such delicate handling to avoid serious degradation, are more stable, last longer, do not deform, and exhibit little stress as well as improved properties that include mechanical, chemical, electrical, biologic, and optical.

Permanent magnet assisted synRM and method for imposing magnetic force thereon

Номер: US2006043812A1

A PMA (Permanent Magnet Assisted) synRM and a method for imposing a magnetic force thereon. Magnets are inserted into outer flux barriers of a plurality of flux barriers formed along the radius of a rotor, and bridges or slim portions are formed on inner flux barriers at positions corresponding to the positions of the magnets so that the magnetic force is imposed on the magnets through coils. Since the number of the flux barriers is sufficiently increased while the amount of the magnets consumed is decreased, the PMA synRM has increased efficiency and reduced production costs.
