Description

Technical Field

[0001] This utility model belongs to the technical field of electronic speed controllers for motors, and specifically relates to a real-time parameter measuring instrument for electronic speed controllers. Background Technology

[0002] An Electronic Speed ​​Controller (ESC) is a power drive device based on power electronics technology and microprocessor control. Its core function is to precisely regulate the speed and torque of an electric motor. It replaces traditional mechanical speed regulation or DC motor speed regulation methods, receiving control signals from a remote control receiver, flight control computer, or host computer to adjust the magnitude, frequency, and phase sequence of the current output to the motor windings in real time. Its core principle is to use power semiconductor devices to perform high-frequency switching, converting the energy of the DC power supply into the drive waveform required by the motor. With its significant advantages such as wide speed range, high precision, fast dynamic response, high efficiency, small size, and ease of implementing complex control algorithms, the ESC has become an indispensable key component in modern drones, electric models, and electric vehicles, greatly promoting the development and widespread application of motor drive technology.

[0003] During use, electronic speed controllers (ESCs) often cannot directly inspect and measure internal data of moving equipment. This makes it difficult to determine the cause of damage or failure after use, hindering the ability to fundamentally resolve the problem. Current technology involves connecting a communication module to the ESC. The ESC sends some parameters, such as throttle signal, voltage, ESC temperature, speed, and motor temperature, to the communication module via a serial port for data reading. However, this data is sent to the over-the-air (OTA) system at regular intervals, assuming the ESC's MCU is functioning correctly. Since the MCU also handles motor drive control, some data is missing or incomplete. Furthermore, the various power supply voltages, input signals, and MCU control signals of the motor and ESC cannot be effectively measured and recorded in real time. In some cases, when the ESC's MCU malfunctions, no measurement data can be obtained at all, making motor and ESC testing extremely difficult. Utility Model Content

[0028] This embodiment provides a real-time parameter measuring instrument for an electronic speed controller. It can directly acquire the power input data of the electronic speed controller through a power signal unit, the throttle signal output through a throttle signal unit, and the Hall signal output of the motor through a motor Hall signal unit. Other dynamic data of the electronic speed controller's operation are connected to the measuring instrument's 18-pin DuPont pin via leads, allowing the measuring instrument's MCU to read them directly. The measured parameters are output via wired or wireless communication through a USB unit and a Bluetooth unit.

[0029] Specifically, the control unit is one of an MCU, CPU, microcontroller, or FPGA, and in this embodiment, an MCU is preferred. It also includes a data storage unit, which includes flash memory connected to the control unit and used to store parameters acquired by the control unit.
