Development history of brushless motors

Early Foundations and Theoretical Foundations
In 1831, Michael Faraday discovered the phenomenon of electromagnetic induction, which laid the theoretical foundation for the development of modern motor technology.
In the 1840s, the first DC motor was successfully developed, marking the practical stage of motor technology.
The Sprout of the Concept of Brushless Motor
In 1949, Slovak engineer Emil Petrash invented the first brushless DC motor, which used the principle of reversing AC current to achieve uninterrupted rotation, marking the beginning of the era of brushless motors.
In 1955, American Harrison first proposed the idea of using transistor commutation circuits instead of motor brush contacts, which became the prototype of the development of brushless DC motors.
Technological breakthroughs and widespread applications
In the 1960s, American electrical engineer Terry Laken invented a three-phase brushless motor with strong magnetic force and high efficiency performance. This innovation breaks the working principle of traditional motors and is hailed as a revolutionary breakthrough in the history of motors, earning Terry Legin the title of the father of brushless motors.
In 1962, the commutation function of brushless DC motors was achieved with the help of Hall elements (Hall effect rotor position sensors), further promoting the development of brushless motor technology.
In the early 1970s, brushless DC motor technology continued to develop, and brushless DC motors using magnetic sensitive diodes for commutation emerged, with much higher sensitivity than Hall elements.
1968: German W Mieslinger proposed a new method of using capacitor phase shifting to achieve commutation, further enriching the technical roadmap of brushless motors.
Globalization Research and Application
Since the 1960s, countries and regions such as Europe, Japan, and South Korea have successively conducted research on brushless motors, which have been widely applied in aerospace, robotics, consumer electronics, and other fields.
Currently, brushless motors have become an important power source in multiple industries, especially in the fields of automobiles, industry, household appliances, medical equipment, etc. Their advantages of high efficiency, long lifespan, low noise, and low vibration have been widely recognized.
