An electric machine for installation to a retaining device includes a stator having an axis, and a torque-support device for supporting the stator against the retaining device to prevent a turning movement around the axis. The torque-support device has an intermediate element, at least two holding support elements for providing support against the retaining device, and at least two stator support elements for providing support against the stator. The holding support elements and the stator support elements possess each a greater rigidity in a circumferential direction in relation to the axis than in any other spatial direction.

An injection molding machine is provided. Permanent magnets are attached to a planetary roller spindle and/or ball screw spindle or to the spindle nut of the injection molding machine. Thus, the permanent magnets are integrated into the planetary roller spindle and/or ball screw spindle or to the spindle nut of the injection molding machine.

According to the invention, an improved copper filling in the slots () of a permanently-stimulated synchronous motor () may be achieved, whereby such a motor is disclosed, comprising a stator (), with parallel-edged slots (), provided with a winding system of flat wires (), whereby the flat wires () each enclose a tooth () and are embodied as a tooth coil (). The flat wires () are wound edgewise such that the narrower side of the flat wire () faces the tooth () and each tooth coil () comprises at least two layers of flat wires ().

A method of maximizing the power or torque output of a synchronous motor with reluctance effect is disclosed. Bases on torque and voltage set points, in the regulation of the synchronous motor, an optimal torque- and field producing current is generated. The method can further generate an optimal voltage which can maximize the power output of a synchronous motor since changes of inductances generated by the current itself can be accounted for.
