Abstract: An energy recovery circuitry for an electric motor with a single phase winding, consisting of two coil sections with central connection, whereby the two coil ends of the coil sections are each connected to ground via a switching element. The task of the invention is therefore, for an electric motor of this type, to ensure, a significantly higher efficiency, a better and defined switching of the coil switching elements, a thermal relief for the switching elements, improved and smoother running, reduced warming of the printed circuit board, improved EMC characteristics, a more robust design of the overall switching, a focused conduction of the losses and an extra protection against any surge impulses from a mains network.
