Abstract

The invention discloses an integrated brushless motor used for automobile EPS and relates to the technical field of brushless motors. The integrated brushless motor comprises a shell, a rear cover arranged at one end of the shell, a rotary shaft with the two ends rotationally arranged on the rear cover and the shell, a controller shell connected with the rear cover and a partition arranged on thecontroller shell and spaced from the rear cover. A cavity is formed in the end, away from the rear cover, of the controller shell and divided into an inner installation cavity and an outer installation cavity through the partition. The end, facing the rear cover, of the rotary shaft is connected with a tail pin used for acquiring the motor rotation speed and steering. The tail pin is connected with a tail inductor. The tail inductor is arranged in the inner installation cavity. The end, away from the rear cover, of the rotary shaft penetrates through the shell and is provided with a connector.The rear cover is further provided with a terminal. One end of the terminal is located in the shell, and the other end of the terminal is arranged in the inner installation cavity. The integrated brushless motor has the effects of being simple in structure, small in occupied space and high in reliability.

Description

technical field [0001] The invention relates to the technical field of brushless motors, more specifically, it relates to an integrated 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 aut...
