Abstract
A protection circuit for an electric motor with a single phase winding, consisting of two coil sections with central tapping, wherein the two coil ends of the coil sections are each connected to ground via a switching element. The task of the invention is for an electric motor of this type to ensure 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.
