Permanent magnetic materials, also referred to as hard magnetic materials, are materials that can maintain stable constant magnetism once magnetized. They play an extremely critical role in the new energy vehicle industry, and are widely applied to core components such as drive motors, auto parts and on-board electronic equipment of new energy vehicles:

1.Drive Motors

One of the most important applications of permanent magnetic materials in new energy vehicles is drive motors.

Energy Efficiency Improvement: Represented by NdFeB magnets, permanent magnetic materials feature high remanence and high coercivity, which can significantly boost motor energy efficiency and lower energy loss.

2.Auto Parts

Anti-lock Braking System (ABS): Permanent magnetic materials are adopted in ABS sensors to accurately detect wheel speed and slip ratio. The system then regulates braking performance to avoid wheel lock-up and enhance driving safety.

Electric Power Steering System (EPS): Permanent magnetic materials are used in EPS motors and sensors, delivering lighter and more precise steering. Besides, the power assist can be automatically adjusted according to vehicle speed and other driving conditions.

Other Components: A large number of micro special motors, including automobile oil pumps, ignition coils, water pump motors, sunroof motors and windshield wiper motors, utilize permanent magnetic materials to upgrade their performance and efficiency.

3.On-board Electronic Equipment

Vehicle Speakers: Permanent magnetic materials constitute the magnetic circuit system of speakers, generating a steady magnetic field to drive the vibration of voice coils and produce sound. Compared with traditional electromagnetic speakers, permanent magnet speakers offer advantages such as superior sound quality, smaller size and lighter weight.

Sensors: Many types of sensors installed in new energy vehicles, such as position sensors, speed sensors and temperature sensors, adopt permanent magnetic materials. These sensors precisely collect various vehicle operating parameters and transmit signals to the control system, realizing intelligent vehicle control.
