Energy saving and sustainability have become hot topics nowadays. Electric transportation applications, such as electric vehicles, always pursue higher energy efficiency other than applications with secured power sources. Therefore, lots of research and development work have been carried out to pursue the energy efficiency, such as redesign the motor itself and/or, use electronic techniques. This invention deploys electronic techniques to pursue higher efficiency. To prove the idea and solutions, 2 prototypes using 2-phase and 3-phase PMBLDC motors have been built for the purpose. They disclose the methods to catch the residual energy from an armature and send it back to the rechargeable power sources without affecting the motor's running driven by switching manner. The implementation is simple and cheap. By recycling the residual energy, it extends the run time of battery systems, achieving higher energy efficiency. The benefit is huge, but not limited to, in economical and environmental fields.
