A method of catching a residual energy stored in an electric coil of a self-inducted back-EMF from an armature of a PMBLDC motor while the motor running driven by a PWM signal is disconnected from a power source and accumulating the residual energy in a storage, and sending a portion of the energy in the storage to a rechargeable power source in order to extend the rechargeable power source's run-time and achieve higher energy efficiency.
