History of brushless DC motor

Brushless DC motor is the most ideal variable speed motor today. It combines the advantages of DC motor and DC motor. It not only has the good regulating performance of DC motor, but also has the advantages of simple structure, no reversing spark, reliable operation and easy maintenance of AC motor. But brushless DC motors are not the first products. Let's look at the development history of brushless DC motor in detail!

1640s: The invention of the electric motor begins

Early models of the electric motor first appeared in the 1640s through the work of Andrew Gordon, a Scottish Benedictine monk and scientist.

1834: The first real electric motor was built

In 1834, Thomas Davenport of Vermont made history by inventing the first official battery-powered electric motor. In 1837, Thomas Davenport and his wife, Emily Davenport, received the first patent for a DC motor.

1955: The era of brushless DC motors begins

In 1955, D. Rison et al. applied for the first patent, replacing the mechanical brush of brushed DC motor with a transistor commutator circuit, which marked the birth of modern brushless DC motor.

1962: Invention of the first brushless direct current (BLDC) motor

Due to advances in solid-state technology in the early 1960s, TG Wilson and PH Trickey invented the first brushless direct current (BLDC) motor in 1962, which they called "DC motor with Solid-State commutator".

1970s-present: Rapid development of brushless DC motor applications

Since the 1970s, with the emergence of new power semiconductor devices and the rapid development of computer control technology, brushless DC motor has been rapidly developed. After that, with the introduction of the mac classic brushless DC motor and its drivers in 1978, and the development of square wave brushless motor and sine wave brushless DC motor in the 1980s, brushless motors really began to enter the practical stage and develop rapidly.
