Abstract
A delivery device for delivering a medium and for heating the medium to be delivered, having a vehicle pump, an electric motor for driving the vehicle pump and a control unit for controlling the electric motor. For heating the medium in the vehicle pump, the control unit is designed to generate a first alternating electrical current in a conductor winding of the electric motor. This first alternating electrical current induces eddy currents in a component of the delivery device, by which the medium can be heated.
Claims11
-10. (canceled)
A delivery device configured to deliver and heat a medium for delivery, comprising:
- a vehicle pump;
- an electric motor configured to drive the vehicle pump and having at least one conductor winding;
- and
- a controller configured to control the electric motor and generate a first electrical alternating current with a first frequency in the at least one conductor winding;
- wherein eddy currents are induced in a component of the delivery device to heating the medium by the first electrical alternating current generated in the at least one conductor winding.
A vehicle comprising
- a delivery device configured to deliver and heat a medium for delivery, having:
- a vehicle pump;
- an electric motor configured to drive the vehicle pump and having at least one conductor winding;
- and
- a controller configured to control the electric motor and generate a first electrical alternating current with a first frequency in the at least one conductor winding;
- wherein eddy currents are induced in a component of the delivery device to heating the medium by the first electrical alternating current generated in the at least one conductor winding, and
- wherein the vehicle pump is a fuel pump for delivering fuel for an internal combustion engine, or a urea solution pump.
A method for delivering and heating a medium by a delivery device having a pump that is driven by an electric motor, the method comprising:
- activating the pump to deliver the medium;
- generating a first electrical alternating current with a first frequency in at least one conductor winding of the electric motor;
- and
- inducing eddy currents in a component of the delivery device using the first electrical alternating current generated in the at least one conductor winding,
- whereby the medium is heated.
A program stored on a non-transitory computer readable medium which, when executed by a controller of a delivery device, commands the controller to:
- activate a pump of the delivery device to deliver a medium;
- generate a first electrical alternating current with a first frequency in at least one conductor winding of an electric motor of the delivery device that drives the pump;
- and
- induce eddy currents in a component of the delivery device using the first electrical alternating current generated in the at least one conductor winding,
- whereby the medium is heated.
A nontransitory computer-readable medium on which there is stored a program element which, when executed by a controller of a delivery device, commands the controller to:
- activate a pump of the delivery device to deliver a medium;
- generate a first electrical alternating current with a first frequency in at least one conductor winding of an electric motor of the delivery device that drives the pump;
- and
- induce eddy currents in a component of the delivery device using the first electrical alternating current generated in the at least one conductor winding,
- whereby the medium is heated.
