Damping systems

Damping systems consist of electromagnetic devices designed to suppress mechanical vibrations. Their component is a piston rod with permanent magnets placed in a cylinder, which consists of rings and ferromagnetic casing, and coils. These coils may be connected in series or in parallel and be connected to an electric power receiver.

Damping systems: characteristics

Damping systems are components whose electrical energy consumer can be a battery, a capacitor or a power electronic converter. The thicknesses of ring magnets and ferromagnetic rings and ring coils are always the same. The use of multiple ring magnets gives a multipolar magnetic field which covers the ring coils of the winding. Any movement of the permanent magnets leads to a change in the magnetic field, which covers the ring coils and generates an electromotive force. The electromotive force induced in the coils, when the electrical circuit consisting of the coils and the receiver is closed, causes current to flow.

Damping, also called quenching, is a phenomenon during which the amplitude of free vibration decreases with time, which is associated with energy loss of the vibrating system. Damping is observed in both mechanical and electrical systems. In the case of traveling waves, damping leads to a decrease in the wave amplitude with increasing distance from the source, which is the effect of energy dissipation. By determining the damping factor, specific damping systems can then be matched to the equipment within which they will occur.

The electrical energy gained can be used to power the connected load or for storage in a battery or capacitor. If there are no end connections in the winding in which the electromotive force is generated, the load losses of electricity are minimized. The damping force of the mechanical element can easily be adjusted by appropriate control of the electric power consumption. This is great for stand-alone adaptive mechanical vibration reduction systems with energy recovery. Besides, this can be used in systems that dampen vertical movements of vehicle wheels, as well as in active noise reduction systems. Each damping module then works optimally for the given application.

Damping systems and modular contactors

The modular contactors, which can be equipped with a diodecay damping system, are a group of actuators for the economical and safe control of current flow in electrical installations. They are perfect for control systems of heating, lighting, ventilation and power supply systems in electric motors. Each module contactor is a type of mechanical switch, mounted on the rail in the control cabinets.

The contactor structure consists of operating contacts, coil and electromagnet. As components, contactor coils should always operate without complications.

The contactor coil support can be used in various applications. This is accomplished by connecting the momentary on button in parallel with the auxiliary contact of the contactor. As soon as the momentary push button is pressed, voltage is applied to the coil and all contacts in the contactors start to conduct. The auxiliary NO contact of the contactor holds the coil and the system is switched off when the momentary push button is activated. This is ideal for installations such as ventilation systems, air conditioning systems, lighting control, and heating control.

The coil as part of the modular contactor contributes to its smooth operation.

The modular contactor, as an electrical switch with contacts in the open state, conducts current under all conditions. Both when the system is operating smoothly and when,

When it is faulty. Damping systems using the principle of vibration damping are used.
