To improve a spherical bearing including a bearing body with a convex spherical surface, a holder, on which the bearing body is disposed, and a bearing shell with a concave spherical surface, the bearing shell being rotatably mounted on the bearing body, in such a way that the mounting of the bearing body on the holder can be carried out a simple and low-cost way, it is provided that the holder is made of a plastics material, and the holder and the bearing body are held non-rotatably with respect to each other. A device for preventing rotation, which holds the bearing body on the holder to be non-rotatable with respect to the holder, may be provided.

Process for the manufacture of rotors for asynchronous electrical motors with spherical air gaps. These rotors are designed as permanent magnets with low coercive force and comparably high electrical conductivity so that eddy currents can be formed as long as rotor rpm is different from the frequency of the rotating field of the stator while these rotors convert to permanent magnets running under synchronous conditions at rated performance. The process steps are the following:1. Milling an iron alloy with at least 5% cobalt to a sheet metal strip.2. Producing of rings by stamping.3. Annealing the rings to at least 1050.degree. C.4. Forming the rings to semi-spherical caps by a deep-drawing process at the annealing temperature pursuant to 3.

A circulation pump is provided. The circulation pump has an electric motor with a stator, a rotor and a motor circuit. The electric motor is disposed in a housing which has a first chamber, in which the stator and the rotor are disposed, and a second chamber, which is separate from the first chamber and in which at least one carrier is positioned, on which at least part of the motor circuit is disposed. The first chamber and the second chamber are connected by at least one connection opening, by means of which at least one electrical element of the motor circuit, which is disposed on the at least one carrier, is in thermal contact with the stator in the first chamber. By providing a housing with separate chambers, the stator in the first chamber may be liquid cooled and the second chamber containing the carrier may be air-cooled.
