5. Main applications for permanent magnets

5.1 Fields of application

The main fields of application for permanent magnets are summarized in Figure B below. and in the table 7 . They can be divided into three groups [40] .

• Electromechanical systems

  They convert mechanical energy into electrical energy, or vice versa. These include electric motors, DC generators and alternators. In the next few years, the latest and most efficient magnets will form the basis of electronically commutated motors, which are both simpler and more efficient than induction motors. We're also talking about electroacoustic actuators (microphones,...
