Internal Brushless Motor Controller 3A-30A | HALL/Sensorless Custom | BOYANG MOTOR

1. Structural Features
It is characterized by its integrated and built - in design. This means that all the necessary components, such as the power stage, microcontroller, and sensor units (if any), are combined into one compact unit and are usually built directly into the motor system or closely integrated with it. This design not only saves space but also simplifies the wiring and installation process, reducing the potential for connection errors.
2. Working Principle
The controller operates by precisely controlling the power supply to the brushless motor. It uses electronic commutation techniques to switch the current in different phases of the motor windings at the right time. For example, in a three - phase brushless motor, it receives feedback from sensors (such as Hall sensors) that detect the position of the rotor. Based on this feedback, the microcontroller within the controller turns on and off the power - switching devices (like MOSFETs or IGBTs) in a specific sequence. This creates a rotating magnetic field that drives the motor to rotate smoothly. It can also adjust the speed of the motor by varying the frequency and duty cycle of the power pulses.

3. Control Functions
It offers a variety of control functions. It can achieve accurate speed control, allowing the motor to operate at a desired speed with high precision. Additionally, it can perform torque control, which is crucial in applications where the motor needs to provide a certain amount of torque under different loads. Some advanced controllers also support position control, enabling the motor to stop at specific angular positions accurately, which is useful in applications like robotics and CNC machines.
4. Advantages
High Efficiency: By precisely controlling the power supply to the motor, it minimizes power losses and improves the overall efficiency of the motor system. This is beneficial for energy - saving applications, such as electric vehicles and home appliances.
Reliability: The integrated design reduces the number of external connections and components, which decreases the likelihood of failures due to loose connections or component malfunctions. Moreover, with built - in protection functions like over - current protection, over - voltage protection, and over - temperature protection, it can safeguard the motor and itself from damage under abnormal conditions.
Compactness and Lightweight: Its compact size and lightweight nature make it suitable for applications where space is limited, such as drones, portable power tools, and small - scale robotic devices.
