摘要:
A self magnetizing motor and a compressor having the same is configured to require a lower starting voltage and to deliver superior performance. In the self magnetizing motor, a magnetic material on an exterior of the rotor is magnetized when power is supplied to a magnetizing unit of the stator. A plurality of conductive bars are inserted on the outer circumference of the rotor core. A spacing distance between outer portions of the conductive bars and inner circumference of the magnetizable material is longer than an air gap between the stator and the rotor. As a result, a magnetic strength of the magnetic material may be increased.

A motor that reduces a cogging torque and rotates at a high speed is presented. The motor comprises: a shaft, a plurality of core blocks coupled to the shaft, a plurality of permanent magnets inserted into each of the core blocks, and an aligning unit, coaxial with the shaft, and disposed between the shaft and the core blocks. The core block includes a plurality of core sheets each having at least a pair of flux barriers formed to be symmetrical to each other about a line of symmetry. A first rib lies along the line of symmetry and a separate anti-deformation rib is positioned within each of the pair of flux barriers. Accordingly, a skew process for a rotor is facilitated. An anti-deformation rib within the flux barrier provides structural integrity for the core block. Accordingly, when the rotor is rotated with a high speed, a bridge is prevented from being deformed.

A microwave oven and control method thereof in which the microwave oven has a magnetron initially driven for a preset period of time to generating an output of at least 20% of a rated output of the magnetron when a cooking mode requiring a low output of less than 20% of the rated output of the magnetron is selected. Further, the magnetron performs the cooking mode by generating the low output of less than 20% of the rated output of the magnetron after the initial driving is completed. In this case, the cooking mode requiring the low output can be a thawing mode, a warming mode, etc. Further, the microwave oven of the present invention is an inverter-type microwave oven.
摘要:
A method of controlling a microwave oven, in which the microwave oven includes a cooking chamber for containing food therein, a cooling fan which circulates air, a magnetron which generates microwaves and a humidity sensor which senses humidity of the cooking chamber. Cooking instruction(s) may be preset or set manually by a user. A first cooking operation is performed according to the set cooking instruction(s). A cook time required to perform a second cooking operation is set based on a time required to perform the first cooking operation. The second cooking operation is performed for the cook time while controlling the output power of the magnetron to perform a rapid cooking operation.

A device for driving a display apparatus includes a scan driver, a timing circuit and a data driver. The scan driver generates a plurality of scan signals activating the scan lines. The timing circuit generates a control signal. The data driver samples a first gray scale voltage signal in response to the control signal, and generates a second gray scale voltage signal to provide a display panel of the display apparatus with the second gray scale voltage signal. The second gray scale voltage signal has a sampled voltage level of the first gray scale voltage signal, and the sampled voltage level is synchronized with the control signal. The deterioration of the display quality due to ripples may be reduced.

A battery cover device for a portable terminal is provided. The battery cover device includes a battery recess formed on a surface of the terminal, a cover plate adapted to attach to and detach from a surface of the terminal to cover the battery recess, and a push rod adapted to protract to and retract from a surface of the terminal. The push rod receives elastic force to protrude from a surface of the terminal and release the cover plate from the terminal. The battery cover device is advantageous in that the cover plate can be easily released by using the push rod or elastic piece, and a battery pack can be easily mounted on a slim terminal.
