The Difference between Brushed DC Motor and BLDC Motor Speed Control Methods

In fact, the control of both motors is voltage regulation, but because the brushless DC uses electronic commutation, it can only be realized with digital control, while the brushed DC commutates through carbon brushes, using thyristors, etc. Traditional analog circuits can be controlled and are relatively simple.

• The Brushed Motor speed adjustment process is to adjust the motor power supply voltage. The adjusted voltage and current are converted through the commutator and brush to change the strength of the magnetic field generated by the electrodes to achieve the purpose of changing the rotation speed. This process is called variable voltage speed regulation.

• The BLDC Motor speed adjustment process is to keep the voltage of the motor's power supply unchanged, change the control signal of the ESC, and then change the switching rate of the high-power MOS tube through the microprocessor to achieve the change in rotation speed. This process is called variable frequency speed regulation.

About the DC Motor

DC Motor is a motor that converts DC electrical energy into mechanical energy. Because of its good speed regulation performance, it is widely used in electric drag. DC motors are divided into three categories: permanent magnet, separately excited and self-excited according to the excitation mode. Self-excitation is further divided into three categories: shunt excitation, series excitation and compound excitation. When the DC power supply supplies power to the armature winding through the brush, the conductor under the N pole on the surface of the armature can flow current in the same direction. According to the left-hand rule, the conductor will be subject to a counterclockwise torque; the part under the S pole on the armature surface The conductor also carries current in the same direction, and similarly according to the left-hand rule, the conductor will also experience a torque in the counterclockwise direction. In this way, the entire armature winding, that is, the rotor, will rotate counterclockwise, and the input DC power energy will be converted into mechanical energy output on the rotor shaft. It consists of a stator and a rotor. The stator: base, main magnetic pole, commutating pole, brush device, etc.; Rotor (armature): armature core, armature winding, commutator, rotating shaft and fan, etc.

The basic structure is divided into two parts: stator and rotor. Note: Do not confuse the commutating pole with the commutator. The stator includes: main magnetic pole, frame, commutating pole, brush device, etc. The rotor includes: armature core, armature (shu) winding, commutator, shaft and fan, etc. Rotor composition The rotor part of a DC motor is composed of armature core, armature, commutator and other devices.

The following is a detailed introduction to each component in the structure.

• Armature core part: Its function is to embed the armature winding and pass the magnetic flux, in order to reduce the eddy current loss and hysteresis loss that occur in the armature core when the motor is working.

• Armature part: Its function is to generate electromagnetic torque and induced electromotive force to perform energy conversion. The armature winding has many coils or glass fiber-coated flat steel copper wire or high-strength enameled wire.

• The commutator is also called the commutator. In a DC motor, its function is to convert the current of the DC power supply on the brush into the AC current in the armature winding, so that the tendency of the electromagnetic torque is stable. In DC In the generator, it converts the AC electromotive force of the armature winding into the DC electromotive force output on the brush end. The commutator consists of a cylinder composed of many sheets insulated with mica. The two ends of each coil of the armature winding are connected to two commutator segments. The function of the commutator in the DC generator is to convert the alternating electric heat in the armature winding into the DC electromotive force between the brushes. Current passes through the load. The DC generator outputs electric power to the load, and at the same time, there is also electric power in the armature coil. There must be current flowing through it. It interacts with the magnetic field to generate electromagnetic torque, and its direction is opposite to that of the generator. The original idea is that only by suppressing this magnetic field torque can the armature rotate. Therefore, in addition to outputting electrical power to the load, the generator outputs mechanical power from the original method, completing the function of the DC generator converting mechanical energy into electrical energy.
