To form the electromagnetic shielding system of electric vehicle's drive motor, the drive motor's power surge protection devices, signal lines and control line protection devices are installed between the outer shield and the drive motor to absorb the induced current which is caused by the motor's electromagnetic field around the power lines and signal lines. In this way, the induced current may not penetrate the shield and form another strong magnetic field, and the drive motor's electromagnetic radiation intensity might meet the exposure level of the medical standard 04 μT in 0.6 meters. Thus drivers and passengers tend to have safer driving in electric vehicles for a long time. Without radiation damage to human body, electric vehicles may be more popular. After the popularity of electric vehicles, electric vehicles will replace the existing gasoline and diesel fuel vehicles to slove the global environment pollution problem fundamentally.
