Abstract:
The invention relates to a braking apparatus for braking the rotating part (1) of a hoisting machine. The braking apparatus comprises one or more brakes (3, 4), which contain altogether at least one movable brake shoe (5, 6), spring elements (7, 8) for activating the brake by moving the brake shoe (5, 6) forward, at least two electromagnets (9, 10), which, when magnetized by a magnetizing current, apply a force of attraction to bodies conducting magnetic flux. The electromagnets are fitted to release the brake (3, 4) by pulling the aforesaid at least one brake shoe (5, 6) back¬ wards by resisting the aforesaid spring elements (7, 8). The brake (3, 4) is fitted to be activated by reducing the magnetizing current of the electromagnet (9, 10). The braking apparatus comprises a power supply circuit (1 1) for the electromagnets, which contains controllable power supply interrupting devices (12, 13, 14, 15). The electro¬ magnets (9, 10) are connected to the said power supply circuit (11) in such a way that the supply of magnetizing current to each electromagnet can be interrupted by means of at least two different interrupting devices (12, 13, 14, 15).
Abstract:
An electric generator includes a wheel coupled to an axle of a vehicle which includes battery. A rotator is fixedly mounted to the wheel and includes a series of magnets positioned so that the north pole of one magnet abuts the south pole of an adjacent magnet. A stator is rotatably mounted to the axle, and includes a mass positioned off-center from the axle for biasing the stator toward a position that is generally stationary relative to the vehicle. The stator further includes a plurality of electric coils for generating electric current when the rotator is moved relative to the stator and the magnetic field of each magnet passes through the plurality of electric coils, the coils being electrically coupled to each other and to the battery of the vehicle to transmit electric current generated from the plurality of coils to the battery.

A control circuit configured to control an electromechanical brake is provided. The control circuit includes: a switching regulator configured to control a magnitude of voltage applied to a brake coil of the electromechanical brake; wherein said switching regulator includes at least one semiconductor switch, one diode, one capacitor and one inductor; the control circuit is configured such that, in operation, at least one signal from a process sub-system specifies the magnitude of the voltage for the brake coil; and at least one brake applying control signal from a safety sub-system can cause the brake coil voltage to be reduced to a level low enough to apply the brake by opening a switch and each brake applying control signal from the safety sub-system has a corresponding diagnostic feedback signal to the safety sub-system that indicates the state of the corresponding switch. A method and a system are disclosed.

L'invention concerne un véhicule guidé sur voie et un agencement de transport associé. Le véhicule comporte des organes de déplacement (2a, 2b), adaptés pour être en prise de support directe avec ladite voie (6a, 6b), un assemblage de transport de charge adapté pour prendre une charge à transporter le long de ladite voie, et un composant (14a, 14b) de freinage par induction du côté du véhicule apte à coopérer avec un composant (10a, 10b) de freinage par induction du côté de la voie, pour générer une force électromagnétique de freinage du véhicule lorsqu'ils sont déplacés l'un par rapport à l'autre dans la direction de déplacement du véhicule. Dans ce véhicule, le composant (14a, 14b) de freinage par induction du côté du véhicule est apte à être déplacé, selon une direction prédéterminée différente de la direction de déplacement du véhicule, par rapport à la position du composant (10a, 10b) de freinage par induction du côté de la voie, ce déplacement faisant varier la force électromagnétique de freinage obtenue.

The invention relates to a housing device (400) for a magnet body for an electromagnetic rail brake for a rail vehicle. The housing device (400) has a first cable feed-through opening for the feeding through of a first electrical connection cable (A) into the magnet body. The housing device (400) is characterized in that a first axial-extent axis (470) of the first cable feed-through opening is arranged at an acute inclination angle (a) to a main surface (410) of the housing device (400) adjacent to the first cable feed-through opening, wherein the first cable feed-through opening is arranged in the center of the rail brake within a tolerance range.
Abstract:
회전체의 제동 시 디스크부와 패드부 사이에 발생되는 마찰력을 단계적으로 증가시켜 상기 회전체에 가해지는 제동 충격을 최소화시킴과 동시에 상기 회전체를 부드럽게 정지시킬 수 있는 마그네틱 브레이크가 개시된다. 상기 마그네틱 브레이크는 매우 심플하고 컴팩트한 구조로 회전체에 가해지는 제동 충격을 최소화시키면서 상기 회전체를 서서히 부드럽게 정지시킬 수 있으므로 정밀한 제어를 필요로 하는 로봇 암의 관절 부위에 적용되어 유용하게 사용될 수 있으며, 심플하고 컴팩트한 구조로 제작되어 설치 공간의 제약을 최소화할 수 있을 뿐만 아니라, 마그네틱 브레이크가 적용되는 각종 장치를 소형 경량화시킬 수 있는 효과가 있다.
