What are the industry applications of brushless motor control boards

Brushless motor control board is the core component to realise the functions of precise driving, speed regulation and protection of brushless motor. With the advantages of high efficiency, long service life and high control precision of brushless motor, its application fields are very wide. The following is a detailed introduction of its specific applications from a variety of fields:

I. Consumer electronics field

UAV: The brushless motor control board is the "brain" of the UAV's power system, which precisely adjusts the rotational speeds of multiple motors by receiving flight control commands to realise the UAV's hovering, flight attitude control (e.g. pitch, roll, yaw), acceleration and deceleration, and other actions. For example, the four brushless motors of a quadcopter UAV need to be coordinated by the control board to complete various complex flight trajectories through the difference in rotational speed.

Power tools: In brushless power tools such as chainsaws, drills, angle grinders, etc., the control board can adjust the output power of the motor in real time according to the load changes to ensure the stability and high efficiency of the tool's operation, and at the same time, it has an overload protection function to prolong the service life of the tool. Compared with traditional brushed power tools, brushless products have lower energy consumption and less maintenance costs due to the presence of the control board.

Home appliances: In some high-end home appliances (e.g. brushless motor-driven hoovers, air conditioner compressors, washing machine drums), the control board can achieve stepless speed regulation of the motor to improve the operating efficiency and quietness of the equipment. For example, hoovers adjust the motor speed through the control board to adapt to the suction requirements of different cleaning scenarios (floor, carpet).

Second, industrial automation field

Automated production lines: In conveyor belts, robotic arms and other equipment, brushless motor control boards can achieve high-precision speed and position control to ensure that the production line's beat is stable. The control board supports a variety of control modes (such as pulse control, bus control), and can be seamlessly connected with PLC and other industrial control systems to meet the flexible needs of automated production.

Pumps and fans: In brushless motor-driven pumps and fans, the control board controls the flow rate and pressure by adjusting the motor speed, which reduces energy consumption by more than 30% compared with the traditional valve adjustment method. At the same time, the control board is equipped with fault diagnosis function (such as over-current, over-voltage, phase loss), which can shut down in time to protect and guarantee the continuity of industrial production.

Third, the field of transport

New energy vehicles: Brushless motor control boards play a key role in the drive system, steering assistance system, cooling fan and other components of electric vehicles. The control board of the drive motor needs to adjust the output torque of the motor in real time according to the signal of the accelerator pedal and the vehicle speed, so as to achieve smooth acceleration of the vehicle and energy recovery (converting kinetic energy into electric energy during braking).

E-bikes and motorbikes: The brushless motor control board receives the speed signal from the handle to control the motor speed, and is equipped with under-voltage protection (to prevent over-discharge of the battery), brake cut-off and other safety functions. Some high-end products also support cruise control, energy recovery and other intelligent functions to enhance the riding experience.

Ships and rail transport: in the propulsion motor of small electric boats and auxiliary motors (such as air-conditioning and ventilation motors and door motors) of rail transport, the control board can adapt to the humidity, vibration and other harsh environments to ensure the reliable operation of the motor.

Fourth, the field of medical equipment

Medical equipment drive: in respiratory machines, haemodialysis machines, electric operating tables and other equipment, brushless motor control boards need to provide high-precision, low-noise drive control. For example, the turbine fan of the ventilator is driven by a brushless motor, and the control board ensures the stability of airflow pressure and flow by accurately adjusting the rotational speed to meet the patient's respiratory needs.

Rehabilitation equipment: In rehabilitation robots, electric wheelchairs and other equipment, the control board adjusts the motor speed and steering according to the user's operating instructions (e.g. joystick control) to achieve smooth movement and posture adjustment of the equipment, and to ensure the safety and effectiveness of rehabilitation training.

V. Aerospace and Special Fields

Aeromodelling and small aircraft: In addition to consumer-grade drones, in aeromodelling aircraft, target planes and other equipment, the control board needs to be lightweight and have strong anti-jamming ability to adapt to high-altitude, high-speed and other complex working conditions to ensure the stable flight of the aircraft.

Special robots: In inspection robots (e.g. power inspection, pipeline inspection), underwater robots, brushless motor control boards need to adapt to extreme environments (high temperature, low temperature, high humidity, dust), and through precise control of motor movement, to achieve the robot's forward movement, steering, obstacle-crossing and other actions, to complete a specific inspection or operational tasks.

VI, agriculture and smart home field

Agricultural machinery: in drone plant protection (pesticide spraying), small harvesters, irrigation pumps and other equipment, the control board can adjust the motor speed according to the operational requirements, for example, the speed of the water pump motor of the plant protection drone needs to be matched with the flight speed to ensure that the pesticide spraying is uniform.

Smart Home: In smart curtains, automatic doors, sweeping robots and other equipment, brushless motor control boards achieve smooth start-stop and precise positioning of motors. For example, the control board of smart curtains receives remote control or APP commands to control the motor forward and reverse to open and close the curtains to the specified position, and the operation process is silent and without stuttering.

Summary

The application scenarios of brushless motor control boards cover a wide range of fields from daily consumption to industrial production, from ground transportation to aerospace, and their core value lies in maximising the performance advantages of brushless motors through precise electronic control, while improving the efficiency, reliability and intelligence of the equipment. With the development of technology, the control board is moving towards higher integration, richer functionality (e.g. support for IoT remote control), and greater adaptability (multi-scenario adaptive algorithms), further expanding its application boundaries.
