The brushless motor is composed of a motor body and a driver, and is a typical mechatronic product.
Series-excited motors are also called series-excited motors, which are connected in series with stator windings and rotor windings. DC motors can be divided into series excitation, parallel excitation, compound excitation and separate excitation series excitation are just one of the excitation principles of DC motors. What's the difference, this kind of motor is mainly used in electric tools and belongs to AC and DC dual-purpose motors or DC motors.
Why are alternators more common?
Alternators are more common than DC generators, mainly because alternators are more efficient in the transmission process. Since the AC signal has less signal attenuation during long-distance transmission, it can maintain a higher voltage over a long distance. In contrast, a direct-current signal has a large signal attenuation during power transmission, and thus it is difficult to perform power transmission over a long distance.
AC motor (alternating-current motor) is mostly abbreviated as AC motor in English.
Where is the motor industry? High-speed direct drive motor is still the mainstream
As the "big heart" of mechanical movement, the motor appears in our living environment all the time, such as shopping malls, office buildings, hotels, schools, hospitals and other places are inseparable from the auxiliary operation of the motor. With the rapid development of industry, the matching of motors in all walks of life is particularly important, that is, high precision, miniaturization and low speed of motors are required.
A single brushless motor is not a complete set of power system. Brushless basic must be controlled by brushless controller, that is, electronic control, to achieve continuous operation.
1. It can replace DC motor speed regulation, frequency converter variable frequency motor speed regulation, asynchronous motor speed reducer speed regulation;
The difference between DC motor and AC motor
The main difference between DC motor and AC motor is the current type, operation principle, structure and speed regulation performance. DC motor uses direct current, good speed regulation performance, suitable for high-precision speed regulation occasions; and AC motor uses alternating current, complex structure, poor speed regulation performance, suitable for household appliances and industrial equipment and other occasions. The choice of motor needs to be based on specific application requirements and scenarios.

Are all generators AC? What is the difference between AC and DC generators
Both the rotor and the stator of an AC generator belong to electromagnets. When current is passed through the stator coil, it creates a rotating magnetic field within the stator coil.
