Abstract: A bobbin for insulating a coil including a base portion comprising an electrically insulative material having an inner surface, an outer surface, an outer periphery, and a pole opening (54). An inner flange extends outwardly from the base portion in a first direction from the pole opening and at least partially defines the pole opening. Moreover, an outer flange extends outwardly from the base portion in the first direction from the outer periphery of the base portion. With this configuration, the bobbin is sized and configured to be placed on a side of the coil to provide ground insulation thereto.
