Abstract
The present invention relates to a cooling system and method for the concentrated motor stator windings of an electric motor. The cooling system and method provides coolant directly onto the motor stator windings and between each adjacent stator winding. The motor housing assists in distributing coolant between each stator winding of the electric motor assembly. Moreover, an insulated sheet and/or tube is insertable between the concentrated motor stator windings. Each is configurable to direct coolant directly on to the stator windings.
