Definitions

• an electromagnetic spring pressure brake with an annular coil carrier and a coil and a friction lining which is connected via an intermediate disc with the armature disc of the electromagnetic spring pressure brake, radially from the outside, ie on the outer circumference, or from the inside, or acts on one of the end faces of a rotating element, ie that the rotating element can be braked. It is also described (claim 4) that e.g. two such brakes can attack the rotating disc. Furthermore, it is pointed out in claim 9 that the rotating element 12 may be a cable drum of an elevator installation or the rotor of an elevator motor.
• the coil carrier for receiving the coil can be made not only round but also rectangular.
• the electromagnetic coil 12a and 12b may be formed in two parts and kidney-shaped. This is done, therefore, that with an additional split anchor plate a dual-circuit (segment-like) is present and as much coil space is utilized. It would also be possible to introduce a so-called oval coil in a bobbin.
• This optimization is achieved by not firmly connecting the friction lining with the armature disc and thus has only one friction surface, but by equipping the rotating element with two friction linings on both sides (ie left and right) and axially connects it via a toothing with a toothed hub , so that it is thus axially movable and has two friction surfaces.
• the armature disc of the brake now presses on the rotating element, i. It was additionally created a second friction surface and thus a double braking torque.
• two rectangular shapes were chosen, with an oval coil in it - or alternatively with two round coils on each other to work as space optimized as possible. ,
• FIG. 1 A further option, several round spring-loaded brakes were distributed around the circumference to press against the rotor with its mutual friction linings and to obtain a very variable variable torque by varying the number of "active" brakes.

• Figure 5 shows a further embodiment of the brake a and b, in which the magnetic coil 2 is not oval, as shown in Figure 1, but divided into two circular coils per brake is executed.
• a circular coil can be cost-effective manufacture as an oval coil.
• FIG. 6 shows a section through the two circular coils.
• FIG. 8 shows that it is also possible to have several round spring-pressure brakes with round armature disks act on the rotor 5.
• the torque can be made even more variable and the failure of a brake are still several other brakes and thus more than 50% of the torque available.
• a brake was not shown to better see the function.
