Introduction to the Control Principles of Electric Vehicle Motors (1) - Development of Electric Vehicle Drive Motors (1)

From the birth of the first electric car in human history in the 19th century to the current popular Tesla brand, the development of electric cars has gone through ups and downs, from the golden age to the lack of attention, and then to the process of regaining attention. Similarly, electric vehicle drive motors have also been able to develop rapidly and steadily with the changes of the times and advances in technology.

The traction motor of electric vehicles generally meets the following requirements:

(1) High operational efficiency;

(2) High power density;

(3) Accurate torque control;

(4) Good speed regulation performance;

(5) Adapt to harsh working environments such as high and low temperatures, vibrations, etc;

(6) Small size suitable for vehicle carrying;

(7) Good sealing performance;

(8) High reliability.
