Brushless DC Motor (BLDC) is a motor that uses an electronic controller to replace the mechanical commutator in a traditional brushed motor to control the rotation of the motor rotor.
Brushless motors are DC motors that do not use brushes and commutators. Due to their high efficiency, controllability, low noise, and long life, they are widely used in various precision instruments and equipment, such as industrial automation, medical centrifuges, smart home devices, etc.
The stator is the stationary part of the motor, usually composed of multiple electromagnetic coils. It is the main source of magnetic field for BLDC motors. By passing electricity through the stator coil, an alternating magnetic field is generated to drive the rotor to rotate.
The stator is usually made of laminated silicon steel sheets to enhance the concentration of the magnetic field and reduce energy loss.
The rotor is the rotating part of the motor, usually made of permanent magnetic material (such as neodymium iron boron magnets). The rotor and stator interact through the magnetic field to achieve rotation.
The rotor of the brushless motor has no brushes, which reduces wear and heat generation, thereby greatly extending the service life of the motor.
Electronic Commutation System (Electronic Commutator):
The commutation of the brushless DC motor is completed by an external electronic controller. The actual position of the rotor is determined by a sensor that detects the rotor position (such as a Hall sensor), and then the electronic switch is controlled according to the position and speed information to ensure the correct switching of the current in the stator coil, thereby controlling the rotation direction and speed of the rotor.
This electronic control method avoids the physical contact between the brush and the commutator, thereby reducing friction loss and noise.
The brushless motor needs to be matched with a controller to achieve precise control and commutation. The controller controls the speed, torque and position of the motor by providing current to the stator winding and adjusting the magnitude and direction of the current.
The main task of the controller is to adjust the operating state of the motor according to the sensor feedback to ensure that the motor runs smoothly and efficiently.
The Hall sensor is used to detect the angle and position of the rotor and provide feedback signals to the controller. Through the Hall sensor, the controller can accurately control the timing of current switching, thereby ensuring precise control of the motor at various positions.
Bearings are used to support the rotor and allow it to rotate smoothly. Brushless DC motors usually use high-precision bearings to ensure that the motor can maintain low friction and stable operation when running at high speed. The working principle of brushless DC motors is based on the law of electromagnetic induction. The current on the stator generates an alternating magnetic field, and the permanent magnets on the rotor interact with the magnetic field of the stator to generate torque. When the direction and magnitude of the current in the stator coil change, the direction and magnitude of the magnetic field also change, thereby driving the rotor to rotate continuously. In brushed motors, the commutator contacts the rotor through brushes to control the switching of current; in brushless motors, electronic controllers and Hall sensors replace this physical structure to achieve a more efficient and frictionless commutation process.
· Long life: Since there is no wear of brushes, the service life of brushless motors is much longer than that of brushed motors.
· Low noise and low vibration: Brushless motors have no friction between brushes and commutators, so they are quieter and vibrate less during operation.
· High efficiency: There is no brush friction loss, and the rotor is made of permanent magnet material, which has high energy efficiency.
· Low maintenance requirements: Since there are no brushes, the complexity and frequency of motor maintenance are reduced.
· Higher power density: Brushless motors can usually provide more power in a smaller volume, which is suitable for applications with compact space requirements.
Comparison between brushless and brushed motors In general, brushless motors have longer life, higher efficiency, stronger precision, lower noise, lower maintenance costs, and more intelligent and extensive applications, making them the first choice for modern production and manufacturing.
Household appliances: such as vacuum cleaners, air conditioners, electric fans, etc. ·
Power tools: such as electric drills, electric screwdrivers, etc.
Robots: used to drive robot joints, electric wheels, etc.
Electric vehicles: motors used to drive electric vehicles.
UAVs: as drive motors for flight power systems.
Brushless motor fans: silent, energy-saving and environmentally friendly, more suitable for home and office use
Large equipment: brushless motors are the first choice for the production and manufacturing of various large equipment because of their precision performance and high efficiency.
Brushless DC motors have gradually become the preferred motor type for many industries and applications due to their high efficiency, low noise, long life and good speed regulation characteristics.
