Problems solved by technology
[0004] In the existing EPS system, most of the booster motors use permanent magnet brushed DC motors, and the DC motors have shortcomings such as commutation sparks, noise, and electromagnetic interference caused by mechanical brushes, which easily cause interference to the electronic equipment of the car; another On the one hand, since the DC motor is set on the rotor, the heat is not easy to dissipate, resulting in serious heat generation and short life, which seriously affects the safety and reliability of the EPS system. Therefore, it is necessary to design a booster motor suitable for the EPS system. It is of great significance to improve the performance of electric power steering system

The invention discloses a brushless motor for automobile EPS, relates to the technical field of brushless motors, and includes a casing, a rear cover, a rotating shaft, a controller casing, a rotor, a magnetic ring, a stator arranged outside the circumference of the magnetic ring, and a winding device. The windings on the stator, the rotor, the magnetic ring and the stator have all been rotated on the same axis as the axis. The stator is composed of several stator cores. The stator core includes an outer arc panel, an inner arc panel, and a Connecting rods between the panels, several outer arc panels are connected end to end to form an outer circumferential surface and connected to the housing, and several inner arc panels are arranged at intervals to form armature slots, and the windings are respectively wound on the connecting rods to rotate The end of the shaft away from the rear cover is passed through the housing and a connector is provided at the end; it has the function of improving the performance of the electric power steering system, thereby improving the safety and reliability of its EPS system.
Description
technical field [0001] The invention relates to the technical field of brushless motors, more specifically, it relates to a brushless motor for automotive EPS. Background technique [0002] With the rapid development of the automobile industry and the deepening awareness of energy crisis, people pay more and more attention to the energy saving of automobiles; the steering performance of automobiles is an important performance in the driving process of automobiles, and the power steering system is also constantly updated. The steering system (EPS, Electric Power Steering) directly provides steering assistance from the power-assisted motor, eliminating the need for power steering oil pumps, hoses, hydraulic oil, conveyor belts and pulleys installed on the engine that are necessary for hydraulic power steering systems. The advantages of anti-interference, safety and handling stability have become one of the focuses of steering system research and development and automotive tech...
