The witching control apparatus includes: a rectifying unit rectifying commercial power; and an active converter including a pair of common switches commonly connected to two phase windings of the two-phase SRM, a pair of first phase switches bridge-connected to the pair of common switches at any one of the two phase windings, a pair of second phase switches bridged-connected to the pair of common switches at the other of the two phase windings and connected in series with each other, and a plurality of current feedback diodes each connected to the switches and operated in operation modes 1 to 3 to drive the two-phase SMR.

Switching control apparatus and method of two-phase switched reluctance motor

Disclosed herein are an apparatus and a method for diagnosing a fault of a multi-sensor of a motor. The apparatus includes: a plurality of tachometers attached to the motor to measure rotation speeds; and a plurality of processors each connected directly to the plurality of tachometers to receive the measured rotation speeds, thereby securing a plurality of directly obtained rotation speeds, sharing the obtained rotation speeds with each other, thereby obtaining a plurality of indirectly obtained rotation speeds, and performing a fault diagnosis on the plurality of tachometers using the plurality of directly obtained rotation speeds and the plurality of indirectly obtained rotation speeds.

Apparatus and method for diagnosing fault of multi-sensor of motor

Disclosed herein is a switched reluctance motor including: a shaft rotatably supporting the switched reluctance motor in an axial direction; a cylindrical part provided at a central portion of the shaft and movable vertically; an elastic member formed to enclose the shaft, formed from an upper portion of the shaft to an upper portion of the cylindrical part to thereby support a rise of the cylindrical part, and having elasticity; commutator segments attached to an outer peripheral surface of the cylindrical part and having a cylindrical shape; brushes contacting or not contacting the commutator segments according to vertical movement of the cylindrical part; and a propeller provided on a lower portion of the cylindrical part and pushing air at the time of rotation to thereby move the cylindrical part upwardly.

Switched reluctance motor having a vertical moving commutator

Disclosed herein is a switched reluctance motor having a double rotor structure. An outer stator salient pole corresponding to an outer rotor salient pole is formed to have an 'E' shape by sequentially disposing a main salient pole, a first auxiliary salient pole, and a second auxiliary salient pole and an inner stator salient pole corresponding to an inner rotor salient pole is formed to have a pi (&#x3c0;) shape by sequentially disposing a first salient pole and a second salient pole, such that a magnetic flux path is reduced, thereby making it possible to prevent the loss of magnetic force.

Switched reluctance motor

An apparatus is provided for driving wheels for an in-wheel system, including: a driving shaft which is the center of rotatable driving; a fixation supporter rotatably supporting the driving shaft and coupled to the driving shaft; an in-wheel motor generating rotational power, which is coupled to the inside of a wheel in which a tire is mounted on one driving shaft in a shaft direction of the fixation supporter; and a balancing member formed on the other driving shaft in the shaft direction of the fixation supporter and formed at a position corresponding to the wheel coupled with the in-wheel motor. According to the present invention, an eccentricity phenomenon which is caused due to inclination of a wheel and a motor in one direction of a fixation supporter can he prevented in an apparatus of driving wheels for an in-wheel system.
