Embodiment Construction
[0033] The invention will be described in further detail below in conjunction with the accompanying drawings.
[0034] figure 1 It is a schematic cross-sectional structure diagram of a motor generator for a hybrid electric vehicle of the present invention. The motor generator for the hybrid electric vehicle includes a casing 1, a permanent magnet 2, a non-magnetically permeable rotor core 3, an olive-shaped core 4, a stator core 5, an armature winding 6, an excitation winding 7, an insulating partition 8 and axis 9;
[0035] The casing 1 is made of a non-magnetic material, and a stator core is fixed inside;
[0036] The stator core 5 is divided into 4X sub-cores that are separated from each other, and the 4X sub-cores are evenly arranged along the circumference; each sub-core has two stator poles, and the yokes of the two stator poles are fixed with tangentially magnetized permanent magnets 2. The radial thickness of the magnet 2 is smaller than the thickness of the two sta...

The invention discloses a motor generator for an HEV (Hybrid Electric Vehicle), and the generator comprises a housing, a permanent magnet, a non-magnetic-conducting rotor core, olive-shaped cores, a stator core, an armature winding, an exciting winding, an insulating separator plate and a shaft. The stator core is divided into 4X sub-cores which are mutually intersected, wherein 4X sub-cores are uniformly arranged in the peripheral direction. The olive-shaped cores are located at an inner side of the stator core and are fixed on the shaft. The non-magnetic-conducting rotor core has 5X curved grooves, wherein the curved grooves are provided with magnetically conductive olive-shaped cores in an embedded manner. The center part of each olive-shaped core is provided with a counterbore for placing a fixing screw, and the fixing screws enable the olive-shaped cores to be fixed on the non-magnetic-conducting rotor core. The exciting winding and the armature winding are isolated from each other without mutual interference, and the reliability is high. The rotor can rotate at a high speed. The outer circumference of the rotor has no protrusion, which reduces the wind resistance during high-speed operation and the harmonic response and noise caused by wind resistance.
Description
technical field [0001] The invention relates to a motor generator for a hybrid electric vehicle, and belongs to the technical field of automobile electric appliances. Background technique [0002] Hybrid vehicles have two sets of power sources, the fuel engine and the motor generator. The motor generator can be used as the starter of the fuel engine to overcome the resistance torque of the engine during the initial starting process, so that the engine can reach a sufficient starting speed; The engine can provide auxiliary power for the fuel engine according to the situation, or it can completely shut down the engine in an appropriate state, and rely solely on the electric generator to provide power. In addition, the motor generator can realize the reverse conversion from mechanical energy to electrical energy, so the mechanical energy of the engine can be generated into electrical energy during the deceleration and braking process of the car, and stored in the car battery. ...
