Description

Technical Field

[0001] This utility model relates to the field of integrated starter motor technology, and in particular to a heat dissipation device for the stator of a disc-type integrated starter motor. Background Technology

[0002] With the rapid development of the automobile and engine industry and the continuous expansion of engine application scope, the requirements for engine safe operation are also getting higher and higher. The stator assembly of the disc starter motor is one of the important devices for powering the load. Once the stator winding cannot dissipate heat in time, it will cause the starter motor to overheat and fail to generate electricity normally, making it impossible for the starter motor to perform power generation tasks for a long time in special operating environments.

[0003] To avoid the above situations, the control strategy for the integrated starter-generator motor includes an over-temperature protection program. When the motor overheats, it will issue an alarm, reminding the operator to stop the machine for inspection, thus protecting the motor itself. Generally, the heat dissipation problem of the stator in an integrated starter-generator motor can be solved by designing heat sinks on the rotor housing, equipping it with a fan for forced cooling, using ambient temperature control, reducing the load, and equipping it with a temperature sensor. Among these methods, optimizing the rotor shape through a hollowed-out, fan-impeller design allows it to dissipate a significant portion of the heat during operation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a heat dissipation device for the stator of a disc-type integrated starter motor, which solves the technical problem that the stator windings of the disc-type integrated starter motor cannot dissipate heat in a timely manner, resulting in overheating and preventing the motor from performing power generation tasks for extended periods in special operating environments.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A heat dissipation device for the stator of a disc-type integrated starter motor includes a rotor, a Hall element, a motor controller, and a host computer. The inner surface of the rotor adopts a hollowed-out fan impeller design, and the side of the rotor is provided with hollowed-out heat dissipation holes. The Hall element is installed on the outside of the stator winding for real-time acquisition of the stator winding temperature. The Hall element is connected to the motor controller, and the motor controller is connected to the host computer.

[0007] Preferably, the hollowed-out fan impeller on the inner surface of the rotor is an integral structure with the rotor, and the number of hollowed-out heat dissipation holes on the side of the rotor is multiple and evenly distributed on the side of the rotor.

[0008] Preferably, the Hall element is fitted to the outside of the stator winding, and the motor controller is equipped with a temperature control alarm program. The motor controller detects the temperature signal collected by the Hall element through the temperature control alarm program and feeds back the detection result to the host computer.

[0009] Preferably, the host computer issues an alarm signal when the stator winding temperature reaches the set over-temperature protection value. The host computer is connected to the cab display terminal, and the alarm signal is an audible and visual signal.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] When the stator assembly of the integrated generator-starter motor is operating continuously, the rotor rotates at high speed. Through the internal and side perforations of the rotor, heat generated by the stator windings is continuously and forcibly dissipated, removing a significant portion of the heat and greatly extending the operating time of the integrated generator-starter motor to meet the power requirements of the load equipment. When the stator winding temperature reaches the set over-temperature protection value, an alarm is triggered on the host computer, reminding the operator to stop the machine for maintenance, protecting the integrated generator-starter motor from damage. This design improves the generator's heat dissipation capacity and automatically alarms and initiates a self-protection command to stop the machine when the set over-temperature protection value is reached, reminding the operator to perform maintenance. Compared to repairing a fault that occurs while the integrated generator-starter motor is operating continuously, this method significantly improves safety and economy. Attached Figure Description

In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0016] This application provides a heat dissipation device for the stator of a disc-type integrated starter motor, which effectively solves the technical problem that the stator winding of the disc-type integrated starter motor overheats due to the inability to dissipate heat in a timely manner, causing the motor to be unable to perform power generation tasks for a long time in special operating environments.

[0017] Example

[0018] The overall technical solution in this application is as follows:

[0019] To address the problems existing in the prior art, this utility model provides a heat dissipation device for the stator of a disc-type integrated starter motor, see [link to relevant documentation]. Figure 1 (Rotor design drawing) The rotor 1 of the starter-generator integrated motor adopts a specific structural design: the inner surface of rotor 1 adopts a hollowed-out fan impeller shape design, and the side adopts a hollowed-out heat dissipation hole 2 design, thus forming a rotor structure that is conducive to heat dissipation.

[0020] A Hall element is installed on the outside of the stator winding. This Hall element is used to collect the temperature information of the stator winding in real time. The Hall element is connected to the motor controller and transmits the collected temperature signal to the motor controller.

[0021] The motor controller has a pre-set temperature control alarm program and is connected to the host computer. In addition, the motor controller is also associated with the cab display terminal.

[0022] When the stator assembly of the starter-generator motor is working continuously, the rotor 1 rotates at high speed with the motor. At this time, the hollowed-out fan impeller inside the rotor 1, together with the hollowed-out heat dissipation holes 2 on the side, can continuously and forcibly dissipate the heat generated by the stator winding, taking away a large part of the heat generated by the stator winding, thereby greatly extending the working time of the starter-generator motor to meet the power demand of the load equipment.

[0023] During this process, the Hall element on the outside of the stator winding collects the winding temperature in real time and continuously sends the temperature signal to the motor controller. The motor controller detects the temperature signal through its internal temperature control alarm program and then feeds the relevant signal back to the host computer.

[0024] When the temperature of the stator winding reaches the set over-temperature protection value, the host computer triggers an alarm. At the same time, the motor controller transmits the alarm signal to the display terminal in the cab, enabling the operator to promptly detect the over-temperature abnormality through audible and visual signals, reminding the operator to stop the machine for maintenance, thereby achieving effective protection of the stator of the starter-generator integrated motor.

[0025] In the above implementation process, the coordination of each component and the workflow can be combined Figure 2 (Diagram of over-temperature protection for integrated starter motor) To understand this, the motor controller is also responsible for processing start signals, outputting three-phase AC power and 28V DC power to the load, etc. It works in conjunction with heat dissipation and over-temperature protection functions to ensure the stable operation of the integrated starter motor.

[0026] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
