Abstract
The invention relates to a motor used in the mixed power vehicle, which comprises a rotor and a stator formed by permanent magnet and iron core. Wherein, the radial section of said rotor is in E-shape; the stator is inside the rotor annular groove whose part at one side of rotor annular groove has a motor case connecting the stator. The permanent magnet is circumferentially arranged at the inner surface of rotor, and with the increase of inner surface radius and in same motor size, since the torque of circumferential magnetic field sensing force is increased, the torque density of motor is improved significantly; the flywheel of motor is integrated with the rotor of electric motor; the rotary inertia of rotor is increased significantly; therefore, it can reduce the number of flywheels on the traditional power integration to integrate the motor and flywheels, with small volume, reduced weight of power integration, axial length, lower short-circuit current and lower instant brake torque.
Description
Technical field
The present invention relates to a kind of motor, particularly a kind of motor that is used for hybrid vehicle.
Background technology
Traditional motor is made of rotor coil, stator armature coil.Permanent magnetic brushless is made of rotor that has permanent magnet and stator exciting coil.The form of the version of magneto and traditional motor all is the version appearance with a kind of internal rotor, and stator structurally is positioned at the outer ring of rotor, and epitrochanterian permanent magnet is fixed in the excircle of rotor; Characteristics such as this kind version is reliable, and the performance performance is good, has the power density height, and is simple in structure, stable and reliable for performance.But there is certain contradiction in its structure: 1, owing to the bigger space of structure needs of stator coil, significantly reduced the radius of armature and rotor magnet on-position under the situation of same overall dimension, reduced the moment of motor peripheral force; Thereby the moment of torsion density of the motor that has reduced; 2,, need to increase moment of torsion, thereby have to increase the diameter of rotor, thereby increased the diameter of motor in order to improve moment of torsion density; 3, the installation of magnet is owing to be subjected to action of centrifugal force, and fixing difficulty needs to twine; 4, the efficient of rotor cooling is not high.
As shown in Figure 3, this motor is used for the coaxial-type hybrid vehicle, because motor is coaxial with engine crankshaft, the rotor of motor and the flywheel of engine are fixed together, highlight above-mentioned defective more, therefore will increase the moment of inertia of engine output, and because due to the electric machine structure, with the length of power assembly is increased, make the front deck difficult arrangement.
Summary of the invention
Technical problem to be solved by this invention provides a kind of motor that is used for hybrid vehicle, to reach the purpose that improves Motor torque density, reduces the length of hybrid vehicle power assembly.
For solving the problems of the technologies described above, technical scheme of the present invention is a kind of motor that is used for hybrid vehicle, comprise rotor, the stator formed by permanent magnet and iron core, described rotor, its radial section is E shape, stator places in the rotor annular groove, a side that is positioned at the rotor annular notch is provided with and the joining electric machine casing of stator, the flywheel that replaces conventional engines, suitable with traditional engine flywheel moment of inertia, thus flywheel on the traditional power assembly reduced, and volume reduces, improve integrated level, reduced the weight and the axial length of power assembly.
A kind of motor that is used for hybrid vehicle, described electric machine casing stretches out a circle ring column along its end face radially to rotor one side, and the electric machine casing axial location is provided with perforation.Engine crankshaft links by perforation and rotor.
A kind of motor that is used for hybrid vehicle, the end face and the stator coil of the spoke shape shell of described electric machine casing link.Can quote engine-cooling system cools off stator.
A kind of motor that is used for hybrid vehicle, described rotor is positioned at the axial outside of its cannelure and is provided with attrition surface.
A kind of motor that is used for hybrid vehicle, described rotor is positioned at its annular notches outside radially and is provided with gear ring.
A kind of motor that is used for hybrid vehicle, described rotor is positioned at its outside radially, cannelure bottom and is provided with the clutch fixing hole.
Owing to adopted said structure, the permanent magnet circumferential arrangement along with the increase of inner surface radius, under the prerequisite of same motor overall dimension, because the moment of Circumferential field induction force increases greatly, has improved the moment of torsion density of motor in rotor inner surface preferably; Stator is intensive layout in inside, can carry out intensive winding: make simple; Handling safety, low short circuit current, low instantaneous braking torque, low magnetic are revealed.The flywheel of engine and the rotor of motor have been made one, the moment of inertia of rotor increases greatly, suitable with the moment of inertia of traditional flywheel, thereby reduced the flywheel on the traditional power assembly, make motor become as a whole with flywheel, volume reduces, and has improved integrated level greatly, has reduced the weight and the axial length of power assembly.
