DC Motor
---Characteristic
1.Compared with the LDO of linear regulators, high efficiency is a significant advantage of DCDC. Usually, the efficiency is above 70%, and the high efficiency can reach over 95%.
2. Adapt to a wide voltage range.
---Classification
In switching DC-DC converters, transistors operate as switches, which means they consume much less power than transistors operating as current dependent sources. When a transistor conducts high current, its voltage drop is very low, while when a transistor conducts high voltage drop, its current is almost zero. Therefore, the switching mode converter has low conduction loss and high efficiency, usually above 80% or 90%. But at high frequencies, switching losses can reduce efficiency, and the higher the switching frequency, the higher the power.
DC motors are divided into three categories based on excitation methods: permanent magnet, separate excitation, and self-excitation, among which self-excitation is further divided into parallel excitation, series excitation, and composite excitation.
So what is the working principle of a DC motor?
The working principle of a DC motor is that the DC power supply is connected to the armature winding through a brush, allowing current to flow through the armature conductor.
There is a magnetic field inside the motor, and the current carrying rotor (i.e. armature) conductor is subjected to the electromagnetic force f=Blia (left-hand rule).
The electromagnetic force generated by all conductors acts on the rotor, causing it to rotate at a speed of N (revolutions per minute) to drag the mechanical load.
The working principle of a DC motor is based on electric induction and Lorentz force, which generate torque through the phase five interaction between the excitation coil and the armature coil, thereby driving the rotation. To maintain the motion of the rotor, it is necessary to continuously change the direction of the current, which can be achieved through mechanical brushing or electronic commutators.
