Power supply part: The power supply part of the brushless motor controller mainly includes the power filter circuit and the power management circuit. The power filter circuit is used to stabilize the power supply voltage, reduce the noise of the power supply, and ensure the normal operation of the motor. The power management circuit is responsible for monitoring and management of the power supply, such as battery level detection and overvoltage protection. Signal processing part: The signal processing part of the brushless motor controller includes sensor signal acquisition, signal processing and control algorithm. The sensor signal acquisition module is used to collect information such as speed, position and temperature of the motor. The signal processing module filters, amplifies and digitizes the acquired signal for the use of subsequent control algorithms. The control algorithm calculates and judges according to the collected signal, generates the control signal, and controls the speed and steering of the motor. Power drive part: The power drive part of the brushless motor controller mainly includes a power amplifier circuit and a drive circuit. The power amplifier circuit is used to amplify the control signal and drive the motor movement. The drive circuit is responsible for converting the amplified signal into the current and voltage signals required by the motor to control the speed and steering of the motor.
