The invention discloses a non-inductive brushless electric machine controller with the function of real time data recording. The non-inductive brushless electric machine controller comprises an MCU (microprogrammed control unit) controlling unit, a driving IC (integrated circuit) unit, a temperature protection unit, a voltage protection unit, a real-time measuring circuit during the operation of an electronic speed controller, a data recording memorizer and a position sensor. The real-time measuring circuit during the operation of an electronic speed controller is used for measuring the real-time parameters of motor current, battery voltage and controller temperature, and transmits the various measured parameters to the MCU controlling unit. The data collection is achieved through the MCU controlling unit, the various data collected is stored in the data recording memorizer. The position sensor is used for measuring flight height and the data of flight height is stored in the data recording memorizer through the MCU controlling unit. According to the non-inductive brushless electric machine controller with function of real time data recording, the information of current, voltage, temperature, motor speed, accelerator opening and the like of a dynamical system is recorded and stored so that operating efficiency of the dynamical system is better improved.

Description

technical field [0001] The invention relates to a non-inductive brushless motor controller, in particular to a non-inductive brushless motor controller with real-time data recording function. Background technique [0002] In recent years, due to the characteristics of small size, light weight, high efficiency, and maintenance-free, DC non-sensing brushless motors have been increasingly used in aviation, marine and other competition-level electric models. [0003] With the widespread use of DC sensorless brushless motors in competition-level electric models, there are also increasing demands on the functionality of motor controllers. The existing sensorless brushless motor controller is only used as the drive control unit of the motor to control the start-run-stop of the motor, and has few functions. During the competition, the operator often wants to know more about the real-time operation status of the power system of the electric model, such as the current, voltage, tempe...

Problems solved by technology

During the competition, the operator often wants to know more about the real-time operation status of the power system of the electric model, such as the current, voltage, temperature, motor speed and throttle opening of the current power system. The brushless motor controller cannot record the power system information of the electric model in real time, so that when the operator wants to optimize his own model, he cannot find the parameter basis, which is not conducive to the improvement of the power system operation efficiency of the electric model
