MONITORING AND CONTROLLING DEVICE FOR MAGNETICALLY CONTROLLABLE ENERGY CONVERSION SYSTEMS

摘要

A device and a circuitry are disclosed for diagnosing, monitoring and/or controlling energy conversion systems, in particular electromagnetically controllable clutches and brakes. The device has a sensor that together with control electronics generates a signal that is supplied to evaluation electronics. The object of the invention is to make a device of this type more widely available and less costly for a wider range of applications. For that purpose, a magnetic field evaluating sensor (2) is introduced into the magnetic field (h) of an energy conversion system (1) and is crossed in a defined manner by the magnetic field (h). The sensor (2) is controlled by a special control signal (uo) that is accordingly modulated, amplified and supplied to the evaluation electronics. In the case of a circuitry, specific mechanical states may be precisely represented without any galvanic connections with the energy conversion system.
