An electric motor that includes a contact arc inducing apparatus is described. The electric motor includes an input terminal configured for coupling with a relay that includes contacts that are electrically coupled when closed and separated by an air gap when open. The input terminal configured to receive power from the relay when the contacts are closed, wherein a predefined arc voltage and arc current facilitate an electric discharge across the contacts when the contacts are transitioned from closed to open. The contact arc inducing apparatus is coupled to the input terminal and configured to provide to the input terminal a current greater than the arc current of the relay and a voltage greater than the arc voltage of the relay during a contact bounce. |
