An interior permanent magnet motor includes a stator comprising a hollow and a plurality of coils provided around the hollow; and a rotor rotatably disposed in the hollow of the stator and comprising a plurality of permanent magnets therein. Each of the plurality of permanent magnets of the rotor comprises a central permanent magnet; a pair of side permanent magnets provided at opposite ends of the central permanent magnet to be inclined toward an outer circumferential surface of the rotor; and a pair of bathers provided between the central permanent magnet and the pair of side permanent magnets, a thickness of each of the pair of bathers is equal to or greater than a thickness of the central permanent magnet. The thickness of the central permanent magnet is greater than a thickness of each of the pair of side permanent magnets.

Interior permanent magnet motor including magnets arranged to be partitioned from barriers

The BLDC motor includes a stator, and a rotor disposed inside of the stator and including a plurality of permanent magnet parts, each of the permanent magnet parts including first and second permanent magnets which are disposed to have an interval therebetween. The rotor includes a slot part including a first portion into which the first permanent magnet is inserted, a second portion into which the second permanent magnet is inserted, and a third portion connecting the first and second portions to each other. The first and second portions have one end portions which are spaced apart from each other by a first distance and other end portions which are spaced apart from each other by a second distance which is shorter than the first distance, and the third portion connects the other end portions of the first and second portions to each other.

BLDC motor

An electric motor is provided. The electric motor includes a hollow-shaped stator configured to have a teeth part protruding on an inner surface thereof, and a rotor configured to be inserted into the hollow-shaped rotor, and including an outer surface facing the teeth part, and a plurality of poles therein. The rotor includes a bridge part disposed between poles and has a front rotor groove and a back rotor groove that are each dented at a front and a back of the bridge part with respect to a rotating direction of the rotor.

A surface-treated electrode active material, a method of surface treating an electrode active material, an electrode, and a lithium secondary battery. The surface-treated electrode active material includes a surface metal oxide layer having higher degree of reduction of a metal than that of a bulk metal oxide layer. The method includes: forming a mixture by adding an untreated electrode active material comprising a metal oxide, and at least one of a basic material and a reducing material to a solvent; and stirring the mixture.

Surface-treated electrode active material, method of surface treating electrode active material, electrode, and lithium secondary battery

A biometric identification apparatus and method using bio signals and an artificial neural network, are provided. The biometric identification apparatus includes: a periodic signal extraction unit which extracts one or more periodic signals from an input bio signal; a template calculation unit which calculates a template value using the extracted periodic signals; a template storage unit which stores a plurality of template values corresponding to a plurality of living bodies; and a reading unit which reads the template value that is most approximate to the template value calculated by the template calculation unit from the template storage unit. Accordingly, it is possible to identify a living body by taking into consideration all of the characteristics of bio signals detected from the living body.

Biometric identification apparatus and method using bio signals and artificial neural network

A biometric apparatus and a method thereof using bio signals are provided. The apparatus includes an ADC, a periodic signal extractor, a template storing portion, a comparator. The ADC performs sampling of an input bio signal to convert the sampled bio signal into a digital signal. The periodic signal extractor extracts the periodic signals from the digital signal. The template storing portion registers a plurality of users and stores periodic signals for the respective registered users in a form of templates. The comparator computes similarity between the periodic signals outputted from the periodic signal extractor and the respective templates to select a template whose similarity is greatest and recognizes a user that corresponds to the selected template as a user who corresponds to the input bio signal.
