Abstract: A brushless DC motor having a plurality of electrical windings and a control circuit operatively connected thereto. The control circuit includes a plurality of switches configured for a time-dependent application of an electrical voltage from an external voltage supply to the windings. A measuring device is also provided for generating an electrical signal depending on the current flow IB from the external voltage supply through the control circuit. An overcurrent fuse is further provided for protecting the control circuit and the windings. In order to achieve particularly high integration of the control circuit, the invention proposes supplying a voltage drop across the overcurrent fuse to the measuring device as an input value.

Abstract: A cooling fan assembly operable for cooling a radiator of a vehicle includes a brushless motor and a fan element having a plurality of fan blades. The brushless motor includes a stator and a rotor. The fan element is attached at the rotor such that rotation of the rotor by the motor imparts rotation of the fan blades to enhance air flow at the radiator of the vehicle. The rotor is a molded polymeric rotor formed by injection molding a thermoplastic material. During injection molding of the rotor, a plurality of magnetic elements are at least partially overmolded by the thermoplastic material to establish the magnetic elements at the molded polymeric rotor. The rotor may have a bell-like shape, and the magnetic elements may be disposed at an inside facing surface of the rotor.
