Motor main body of automobile cooling fan

Abstract

The invention discloses a motor main body of an automobile cooling fan. The motor main body comprises a heat sink, an armature assembly, an outer rotor, and a rear end cover. A conductive bracket is provided with three mounting holes. Conductive links are inserted into the mounting holes to. Four metal connecting pieces are embedded in the conductive bracket. One end of each of the four metal connecting pieces extends to a wire harness installation area and is provided with a wire harness fixing pin. The other end of each of three metal connecting pieces is provided with a link fixing pin. Theremaining one metal connecting piece is provided with a ground electrode connected to the heat sink. Four wire harnesses are installed in the wire harness installation area. The four wire harnesses are fixedly connected to the wire harness fixing pins, respectively. The front ends of the three conductive links are electrically connected to the three-phase windings of the armature assembly. The tail ends of the three conductive links are fixed to three link fixing pins one to one. The motor main body has no control part so as to be easily connected to an external controller. A large number ofmatching and debugging operations are not required in use, which reduces the workload.

Description

technical field [0001] The invention relates to a motor main body, in particular to a motor main body of an automobile cooling fan. Background technique [0002] Motors are commonly used power devices and are used in various industries. At present, brushless motors can be controlled by PCBA boards. The applicant has previously applied for a driving motor for an automobile cooling fan, and its patent application number is: CN201810896239.X. For the specific structure of the driving motor, please refer to the application document. However, the structure of this drive motor still has the following disadvantages: the drive motor has a built-in controller component, and the PCBA board in the controller component is used to control the current direction of the motor to ensure the normal operation of the motor. However, when such a motor is installed on a vehicle, it needs to be connected with the main controller of the vehicle for signal connection, and finally the control of the...

However, the structure of this drive motor still has the following disadvantages: this drive motor has a built-in controller component, and the PCBA board in the controller component is used to control the current direction of the motor to ensure the normal operation of the motor

However, since the manufacture of the motor is provided by the motor manufacturer, the motor control part of the PCBA board is also manufactured and designed by the motor factory; while the main controller of the car is designed and provided by other manufacturers, which may lead to differences between There are deviations in the communication and control principles, so a lot of debugging and matching work needs to be completed when using it, resulting in an increase in workload
