Abstract: A control system (1) comprising a multi-motor converter (PWR) for the closed-loop control of a number of n EC motors (M1, . . . , Mn) operated in parallel, the rotor position of each motor being detected without a sensor and being controlled by the converter they share.

Abstract: An actuating device for adjusting at least one valve needle of an injection molding apparatus with a hot runner manifold that has disposed thereon at least one hot runner nozzle with at least one valve needle extending there-through which may control the melt flow through the hot runner nozzle. The actuating device has a support plate that is connected to the at least one valve needle and movable in a first direction relative to the hot runner manifold. The actuating device further includes a reciprocating device for moving the support plate in the first direction relative to the hot runner manifold, wherein the reciprocating device includes a slider mechanism and an actuation drive that is connected to a trigger device for generating a linear motion, wherein the slider mechanism has at least one thrust rod that is disposed in a second direction at an angle relative to the first direction.

Abstract: The present disclosure is directed to an injection nozzle for an injection molding device comprising a drive train for at least one closure element arranged movable in a nozzle head in a first direction. The drive train comprises a cam mechanism with a cam head comprising a wedge and at least one side plate. The wedge and the side plate are together arranged moveable in a second direction. Per closure element the wedge comprises at least one first drive surface which interacts with a second drive surface arranged at the closure element at least during closing of the closure element. The at least one side plate comprises a third drive surface which interacts with a fourth drive surface arranged at the closure element at least during opening of the closure element.
