Abstract: A domestic ice-cream maker comprises a refrigerated bowl-shaped container for an ice-cream mass; a rotatable stirring tool associated with such container for scraping off ice-cream freezing at a refrigerated surface of the container; and a single-phase synchronous motor for rotating the stirring tool, such motor having a maximum permissible operating temperature for making the ice-cream. A transmission path including a reduction mechanism extends between the synchronous motor and the stirring tool. Backlash is provided in the reduction mechanism as overload protection for the synchronous motor, the backlash acting in both directions of rotation of the motor and corresponding in each such direction of rotation to at least 10 revolutions of the motor, the motor, upon being blocked in either direction of rotation, reversing its direction of rotation and passing through the range of the backlash without exceeding its maximum permissible operating temperature.

Abstract: A protection against overheating not only of the heat transmitting component (2), but also of the components (3) surrounding said component is achieved. A latent heat store (1) is provided between the heat transmitting component (2) or a part thereof and a component (3) to be protected from overheating or a part thereof. The latent heat store (1) comprises a latent heat storing agent, whose melting-point T is between the operating temperature of the heat transmitting component (2) and the maximum permissible temperature of the component (3) to be protected. The quantity is proportioned so that the storage capacity of the latent heat store (1) is sufficient for the amount of heat maximally to be transmitted by the heat transmitting component (2). Between the heat transmitting component (2) and the latent heat source (1) and between the latent heat store (1) and the component (3) to be protected a thermal insulation (4,5) is provided. The melting-point T of the latent heat storing agent and the thicknesses d of the insulations (4,5) are proportioned so that the temperature gradient .DELTA.T/d from the heat transmitting component (2) which is at operating temperature to the latent heat store (1) is greater than the temperature gradient .DELTA.T/d from the latent heat store (1) to the component (3) to be protected.

Abstract: A single-phase synchronous motor with a two-pole permanent-magnet rotor of a magnet material having a remanence B.sub.r, a specific density .rho., a rotor diameter d, a resulting detent torque of an amplitude M.sub.k1, and a mass moment of inertia J. In the single-phase synchronous motor, high-energy magnet materials are used for the rotor, which rotor material is characterized by the constant ##EQU1## The moment of inertia J and/or the detent torque M.sub.k1 should be influenced in such a way that the natural frequency ##EQU2## of the low-amplitude freely oscillating system comprising the rotor and the load is unequal to the mains frequency .omega..sub.e. In the design of a single-phase synchronous motor this may result in, for example, the air gap at the narrowest point being enlarged in comparison with the dimensions of conventional motors having rotors with conventional permanent magnet materials.
