1. A closure for a storage compartment of a motor vehicle, comprising: at least one electromagnet, wherein the at least one electromagnet comprises an armature, wherein the armature can by moved by excitation of the electromagnet, wherein a movement of the armature can be transmitted to at least one locking element, wherein the at least one locking element, due to a restoring force of a spring, is in a locked position for the storage compartment when the electromagnet is not energized,means for generating an electric current for exciting the electromagnet,means for measuring the electric current flow used for exciting the electromagnet, wherein the means for generating the current are designed to control the electric current such that, after turning on the current after measuring when a maximum current is reached and subsequent dropping below said maximum current, the current is reduced to a predetermined minimum value, wherein the minimum value is dimensioned such that the armature is held in its position against the spring force acting on the armature. 2. A closure in accordance with claim 1, wherein the electrical current for exciting the electromagnet is controllable such that the electric current can be continuously increased over a first time period until the measured maximum current is reached. 3. A closure in accordance with claim 2, wherein the electrical current can be reduced to the predetermined value for a second time period, wherein the locking element is in an unlocked position for the storage compartment over the second time period. 4. A closure in accordance with claim 3, wherein the electrical current, after the end of the second time period, can be controlled such that it is continuously reduced over a third time period. 5. A closure in accordance with claim 4, wherein the electric current can be increased exponentially or linearly during the first time period and/or decreased during the third time period. 6. A closure in accordance with claim 1, further comprising means to determine the predetermined minimal value of the current, wherein the minimal value of the current depends on the ratio between the measured maximum current and the measured value at which the maximum current is not reached. 7. A closure in accordance with claim 1, wherein the predetermined minimal value can be determined via a table, wherein in the table the minimum value of the current is assigned to the ratio between the measured maximum current and the measured value at which the maximum current is not reached. 8. A closure in accordance with claim 4, wherein the first time period lies between 5 and 100 milliseconds and/or wherein the second time period lies between zero and 300 milliseconds and/or wherein the third time period lies between 50 and 500 milliseconds. 9. A closure in accordance with claim 1, wherein the closure comprises a sensor for each of the at least one electromagnets, wherein the sensor makes it possible to detect if the armature of the electromagnet is in a position that corresponds to the locked position of the corresponding locking element. 10. A closure in accordance with claim 1, wherein the closure comprises a sensor for each locking element, wherein the sensors make it possible to detect if the locking elements are in the locked position when the storage compartment is closed. 11.
