Abstract: A method for joining a first component made of a plastic material, in particular a thermoplastic and/or thermosetting plastic material, to a second component by applying a joining element on the first component, wherein the joining element has a supporting plate formed of a thermoplastic and/or thermosetting plastic material and comprising a connecting means and a supporting plate bore. A joining element for creating a junction in accordance with the method, is also disclosed. Furthermore, a device, in particular for performing the method, is disclosed.

Abstract: The invention relates to a solid rivet having a die head (5) and a shaft (6) which is aligned axially with the die head (5) wherein the maximum diameter of the die head is larger than the outer diameter of the shaft (6). In order to enable a solid and reliable connection even of FRP component parts with one another without this signifying increased manufacturing expense it is proposed according to the invention that the shaft (6) has at least one end section (11), an intermediate section (10) and a head section (9) wherein the outer diameter of the intermediate section (10) is smaller than the outer diameter of the end section (11).

Abstract: This invention firstly relates to a method for joining a first component made of a plastic material, in particular a thermoplastic and/or thermosetting plastic material, to a second component by applying a joining element on the first component, wherein the joining element has a supporting plate formed of a thermoplastic and/or thermosetting plastic material and comprising a connecting means and a supporting plate bore. The method comprising the steps of incorporating a bore into the first component; welding the supporting plate to the first component; and joining the first component and the second component by incorporating a joining means arranged on the second component into the connecting means. Due to welding of the supporting plate to the first component, a rivet joint, otherwise generally required for joining the supporting plate to the first component, can be omitted, whereby the production of a junction by means of the inventive joining means is considerably simplified.

Abstract: A control system for an M-phase a.c. machine which measures the currents in at least (M-N) phases, where N=2 if M is even and N=1 if M is uneven, measures the instantaneous values of the voltages in (M-N) phases and obtains control signals for alteration of the input voltage and/or current to the motor to maintain the motor in an efficient running condition.
