The present invention provides an adapter device for attaching a cooling fan to a motor in a cooling fan module for an automotive cooling system. The device includes a connection member for rotationally fixed connection with a rotor of the motor. The rotor is surrounded by a stator comprising windings or coils arranged annularly about the rotor. The connection member is separate from the rotor and is configured for insertion into a central aperture or opening of the rotor for connection thereto via an outer surface of the connection member. An attachment member is provided at an end region of the connection member for attachment of a cooling fan thereto. The adapter device is configured to accommodate at least one bearing which supports the rotor for rotation about a rotational axis.

Adapter device for attaching a cooling fan to a motor and cooling fan module for an automotive cooling system

The present invention provides a cooling fan module for an automotive cooling system, comprising: a cooling fan having a hub and a plurality of fan blades extending from the hub; a motor for driving the cooling fan, the motor having a rotor mounted or supported for rotation about an axis on a fixed shaft or axle of the motor; and an adapter device by means of which the cooling fan is attached to the rotor, wherein the adapter device comprises a connection member for rotationally fixed connection to a body of the rotor, and an attachment member for attachment with the hub of the cooling fan. The connection member may comprise a stub, which is desirably inserted into a central opening or aperture of the rotor body and the adapter device desirably accommodates at least one bearing upon which the rotor is supported for rotation about the rotational axis.
