Description
Technical field
The present invention relates to a kind of electric machine structure.
Background technology
Motor that uses on the electric automobile and industrial motor have a great difference, and industrial motor continuous operation is on nominal torque point, so motor only needs to have very high efficient on nominal torque point.The expansion speed of conventional motors than the ratio of rated speed (maximum speed with) generally all less than 2, but the expansion speed of automobile-used motor ratio requires to reach 4 or higher, the used for electric vehicle motor adopts the method for designing of conventional motors more at present, use frequency converter to realize the high-speed cruising of motor by various weak magnetic means, this method greatly reduces the efficient of motor when the little moment of torsion of high speed moves, so and is not suitable for being applied on the electric automobile.
Summary of the invention
Purpose of the present invention is exactly in order to overcome the above problems, and a kind of electric machine structure that is easy to control, be suitable for used for electric vehicle is provided.
For achieving the above object, the present invention proposes a kind of electric machine structure of automatic adjusting magnetic flux, comprise stator 2, rotor 3, water jacket 5, rotating shaft 8, housing 7, shaft seat, described water jacket is fixed in the described housing, described stator is fixed in the described water jacket, described left and right sides end cap is fixed in described water jacket two ends respectively, and described rotating shaft is installed on the housing by shaft seat; Also set up centrifugal mechanism 1, slide mechanism 9, described slide mechanism axially is movably set in the described rotating shaft; Described rotor is fixedly arranged on the described slide mechanism; Described centrifugal mechanism one end is connected with described housing, and the other end is connected with described slide mechanism one end or rotor.
Above-mentioned electric machine structure also comprises telescoping mechanism 4, is arranged between the described housing and the slide mechanism other end, or is arranged between described housing and the rotor.Described telescoping mechanism (4) is an elastic component.The preferred spring of described elastic component.
Above-mentioned electric machine structure, described centrifugal mechanism comprises first centrifuge arm 11, centrifugal 13, second centrifuge arm 12, described first centrifuge arm, one end is connected in described housing, the other end connects described centrifugal, described second centrifuge arm, one end is connected in described slide mechanism or rotor, and the other end is connected in described centrifugal.
