Dynamically high-quality supporting magnets, and combinations of supporting-propulsion systems

摘要

In order to achieve good dynamic adjusting characteristics in the case of electrical supporting magnets, the stationary component of the supporting force is generated by a coil whose current is taken from a voltage source (battery) which is not adjustable (from the dynamic viewpoint). The adjustable flux component is generated by a control coil having a relatively small number of turns and a separate voltage source (control voltage). In order to limit interactions between the control circuit and the basic load circuit, current stabilisation is used in the latter, the major components not being mechanically connected to the magnet which is to be controlled. The adjusting characteristic of the magnet is determined by means of the relatively small inductance of the control circuit (Figure 1a). A series circuit consisting of a plurality of magnets which are regulated individually is proposed as a possibility for current stabilisation, so that neither additional mass nor additional losses occur. Furthermore, reference is made to an actively controlled stabilisation circuit and a combination of linear drive and support regulation. Using the measures described, a rapid change in the magnetic forces and a system improvement can be achieved with a relatively low adjusting power. IMAGE
