摘要： An electrical drive device comprising a stator arrangement of the claw pole type surrounding a stator chamber or compartment and producing therein at least one magnetic field containing at least one rotary field component. There is provided a permanent magnet-rotor arranged in such rotor chamber in such a manner that it rotates in synchronism with such magnetic field and a hysteresis magnetic coupling, the driving part of which is form-lockingly connected with such rotor and the driven part of which is force-lockingly secured to a shaft constituting the power take-off shaft of the drive device. The stator arrangement, the rotor, the driving part of the hysteresis magnetic coupling and the driven part of such coupling are all housed in a common housing.

摘要： A simple, inexpensive, and effective linear actuator design comprises a motor adjacent to a speed-reducer, with the driven stem of the speed-reducer passing through the rotor of the motor. The stem has one bearing at one end of the reducer and its second bearing at the end of the motor, in a bearing part likewise serving as a bearing for the rotor. The distance between the two bearings is increased, and the second bearing includes a socket which has a radial elasticity owing to the fact that it is monolithically joined to the fixed bearing part via a thin portion. This second bearing part is advantageously of synthetic material. The rotation of the stem actuates a driven linear-motion part, which is prevented from rotating and which executes a translatory movement.

摘要： In order to obtain very long operating autonomy without maintenance, with low power consumption and low wear and tear, both the energizing and de-energizing of a DC motor are controlled by an electronic switching circuit providing bounce-free switching. A switching-on control circuit actuates the switching circuit, causing it to energize the motor. A switching-off control device, comprising a rotary component connected to the motor shaft and including contact elements responsive to the position of the rotary component, actuates the switching circuit to cut off the power supply to the motor after the rotary component has rotated through a predetermined angle. The arrangement is advantageous for driving apparatus which is not easily accessible and lacks reliable mains power. Another useful particularity consists in a multiple plug device whereby the rate of intermittent driving may be varied within the range of 1 day to 31 days.
