A centrifugal blower () for an electric-drive vehicle () having three independent air outlets () receiving air from a single impeller (). A first radial airflow () provides cooling air to an alternator () of the vehicle, a second radial airflow () provides cooling air to a control group () of the vehicle, and an axial airflow () provides cooling air to an electric drive motor () of the vehicle. The first and second radial airflows are provided through respective first and second outlets () formed at radially separated locations in a perimeter of the blower housing (). The axial airflow is provided through a generally ring-shaped third outlet () formed in a sidewall () of the housing. An air dam () provides a pressure barrier between the radial and axial airflows proximate a location where the first radial airflow is redirected to flow in a generally axial direction.

A multiple outlet centrifugal blower has an impeller that provides both radial and axial airflows that are independent of each other such that an obstruction in one of the airflow does not substantially affect the flow of the other. The blower typically includes a housing having an inlet port, first and second outlet ducts, and an impeller rotatably positioned and supported within the housing. The first outlet duct is configured to receive airflow in a radial direction with respect to the blades of the impeller, and the second outlet duct is configured to receive airflow in an axial direction with respect to the blades of the impeller.

A method for reducing the movement of a rotor cage relative to a rotor core in a rotor assembly, such as found in a squirrel cage AC induction motor. Movement is reduced by forming a depression in a portion of a rotor bar of the rotor cage. Formation of the depression displaces rotor bar material adjacent to the depression. The displacement of rotor bar material deforms an adjacent portion of the rotor core thereby fixing the rotor cage to the rotor core. The reduction in movement between the rotor cage and the rotor core is dependent on various depression geometries, quantities and positions. The invention further includes a rotor assembly with a substantially cylindrical rotor core having longitudinally extending slots on its outer surface. A rotor bar is positioned in at least one of the slots. The rotor assembly has at least one depression formed in a rotor bar which displaces rotor bar material into the rotor core, whereby the rotor bar is substantially fixed into a desired position with respect to the rotor core.
