Stator structure

Abstract

A stator structure includes a main body having multiple frames each having an arc panel, a main tooth, at least one secondary tooth, at least one main coil and at least one secondary coil. The main tooth and the secondary tooth are disposed at one face of the arc panel. The main coil is installed at the main tooth, and the secondary coil is installed at the secondary coil. A rotor is penetrated through the stator structure. The frames are in a multi-layer circular arrangement at the rotor, and a dislocation angle exists between the frame at any layer and the frame at the neighboring layer.

Description

technical field [0001] The invention relates to a stator structure, in particular to a stator structure applied to a linear motor. Background technique [0002] Electric vehicles have the advantages of cleanliness and low noise, and electric vehicles use batteries as the power source of electric vehicles, but the energy density of existing batteries is insufficient and the price is high, resulting in insufficient endurance of electric vehicles, and the battery charging time is long And charging equipment is not popular. [0003] The above two factors reduce the utilization rate of electric vehicles, so some electric vehicles will be equipped with mileage extenders to overcome the problems caused by the above two factors. [0004] The mileage extender is a linear motor, which can simultaneously have the functions of a linear motor and a linear generator, and must meet the requirements of high density power (POWER DENSITY) and high specific power (SPECIFIC POWER), but the exi...

[0002] Electric vehicles have the advantages of cleanliness and low noise, and electric vehicles use batteries as the power source of electric vehicles, but the energy density of existing batteries is insufficient and the price is high, resulting in insufficient endurance of electric vehicles, and the battery charging time is long Not popular with charging equipment

[0003] The above two factors reduce the utilization rate of electric vehicles, so some electric vehicles will be equipped with mileage extenders to overcome the problems caused by the above two factors

[0004] The mileage extender is a linear motor, which can simultaneously have the functions of a linear motor and a linear generator, and must meet the requirements of high power density (POWER DENSITY) and high specific power (SPECIFIC POWER), but the existing linear motor Taking stacked silicon steel sheets as the design consideration, however, this design is limited by the processing technology, so it can only use a two-dimensional stator structure, and the effective shaft length cannot be shortened due to the turning of the coil, and the amount of copper wire is large, which causes copper loss and is difficult to lift. The overall efficiency, so how to improve the aforementioned stator structure becomes an issue that can be discussed
