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 Ifrom 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.
