    摘要: 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.

    摘要: The invention relates to a device for improving the stability of rotation of the rotor of a single-phase synchronous motor mounted in an apparatus housing. The motor exhibits an average motor torque on which strong alternating torques are superimposed and which drives a preferably rotating load. The rotating load may be a small domestic appliance such as a citrus-juice extractor, a knife sharpener, or a dry-shaver with rotatary cutters. The device is constructed in such a way that the rotor is influenced by an additional mechanical compensation torque which acts outside the load-transmission path and which counteracts the electro-mechanical alternating torques of the motor for a given, preferably positive, direction of rotation of the rotor, the positive direction of rotation being that direction in which the torque exerted on the rotor by the current becomes initially zero and in which subsequently, shifted through a small angle, the magnetic detent torque, which exists when the stator coils are not energized, also becomes zero. And in this position a stable rest position of the rotor is provided and the opposite direction of rotation is blocked. Blocking is effected by means of a unidirectional device. 1

    摘要: A method for making the shaving head of a dry-shaving apparatus with an effective shaving area of a desired shape, in which a shear foil is mounted in an arcuate condition in a shaving-head frame without the cutter so that the foil assumes a free clamping curvature which is not influenced by the cutter, a normal-pressure distribution is applied perpendicular to the foil curvature which simulates the pressure distribution between the cutter and the foil in conformity with a desired effective shaving area, so that the shear foil experiences in said effective shaving area a deformation relative to the free clamping curvature, the simulated pretension curvature thus obtained corresponding to the desired normal-pressure distribution on the cutter in the desired effective shaving area relative to the shear foil.The cutting edges of the cutter are curved in conformity with the pretension curvature of the shear foil thus determined and the cutter, whose shape is in conformity with said pretension curvature, is pressed into the shear foil with the force which provides the desired normal-pressure distribution.

    摘要: A drive mechanism for a domestic vibration-type apparatus is provided, in which the rotor shaft (19) of a single-phase synchronous motor drives a cam-and-follower mechanism which converts the rotary motion of the rotor into a vibratory motion, the rotor and the stator having a main field direction (22) and (16), respectively. The longitudinal axis of the mirror-symmetrical cam extends at an angle to the main field direction (22) of the rotor. Rollers (31, 31a) which follow the cam (21) are arranged on a pivotal arm which is pivot about its central portion and a vibratory part (39) to be driven is arranged on the driving end (35) of this pivotal arm. As they cooperate with the cam the rollers are constantly in contact with the cam profile. At the end of the transmission path, which exhibits backlash, vibratory part (39) cooperates with a spring (38) which urges one of the rollers against the cam, causing the position of the cam relative to the direction of magnetization of the rotor to be changed so that the rotor is forced out of a position in which the direction of magnetization of the rotor and the main field direction of the rotor extend parallel to each other, by means of the spring (38), preferably in the positive direction. In this parallel position the vibratory part (39) is situated near of its reversal point. To obtain a further noise reduction a unidirectional blocking device is included.
