Embodiment Construction

[0032] figure 1 It is a longitudinal sectional view of embodiment 1 of a kind of automobile starter generator of the technology of the present invention. Among them, 1 shaft, 2 rotors, 3 fixed nuts, 4 permanent magnets, 5 armature windings, 6 stator cores, and 7 engine casings. An automobile starter generator, which is an outer rotor structure, the cup-shaped outer rotor is fixed on the shaft, 2K rectangular holes are evenly distributed on the peripheral surface of the outer rotor, K is a positive integer, and the section of the rectangular hole is fan-shaped when viewed from the side; the stator The iron core is fixed on the engine casing, and the stator iron core is composed of 3K evenly distributed "匚" shaped stator iron cores, and the yoke in the middle of the stator iron cores is parallel to the axis.

[0033] There is a fan-shaped stator tooth at both ends of the sub-stator core; all the stator teeth face the outside of the circumference and the distance between the sta...

Abstract

The invention discloses a vehicle start generator and belongs to the technical field of vehicle motors and electrical appliances. The vehicle start generator is formed by a shaft, a rotor, a stator core, armature windings, permanent magnets and a bearing; 2K rectangular holes are evenly distributed in the circumferential surface of the rotor, and K is a positive integer; the stator core is formedby 3K evenly-distributed 'U'-shaped sub-stator cores, and two ends of each sub-stator core are respectively provided with a stator tooth provided with fan-shaped sides; one permanent magnet is clampedin the yoke of the center of each sub-stator core, and the root of each stator tooth is surrounded with one armature winding. The vehicle start generator has the advantages of short magnetic circuit,short enameled wire and quite low in consumption of iron and copper, the advantage that the rotor is magnetic conductive is fully developed, and high application values on the vehicle start generatorare achieved.

Description

technical field [0001] The invention relates to an automobile starter generator, which belongs to the technical field of automobile motors and electric appliances. Background technique [0002] The starter generator can not only be used as a motor to start the engine, but also can be used as a generator to provide electrical energy for electrical equipment. It is a key component of new energy-saving vehicles such as hybrid vehicles and idle stop vehicles. With the development of automobile technology, starter generator technology is more and more used in automobiles. [0003] For vehicle starter generators, in the existing technology, the applicant once filed a patent application number 201410073698.X: a brushless DC reluctance starter generator. Adjust the excitation current to maintain the stability of the output voltage. When starting, rely on the reluctance torque to rotate, the armature coils are connected in series, the starting torque is large, and it is suitable for...
