Abstract
A motor assembly includes a motor, a controller for controlling at least one aspect of operation of the motor, a housing, and an insulation system. The housing defines a motor chamber at least substantially receiving the motor and a controller chamber at least substantially receiving the controller. The housing includes a generally annular sidewall at least in part defining the controller chamber. The sidewall includes an electrically conductive portion adjacent the controller, such that a generally radially extending potentially electrical pathway is defined between the controller and the electrically conductive portion. The insulation system extends along the electrically conductive portion, in electrically insulative engagement therewith, to at least in part obstruct the pathway.
