METHOD AND APPARATUS FOR A MAGNETICALLY COUPLED EDDY- CURRENT DYNAMOMETER

摘要

The present invention provides a magnetically coupled dynamometer (10) that dispenses with the need to physically couple said dynamometer (10) to the shaft (30) of aforementioned rotating machine (20) and facilitate the rapid testing of multiple rotating machines (20) by inherently facilitating the rapid removal and replacement of a rotating machine (20). The magnetically coupled dynamometer (10) apparatus of the present invention comprising of a first portion (10a) that includes a conductive disk (40) mounted on a rotating shaft (30) of a rotating machine (20) that is placed in close proximity to a second portion (10b) that includes an induction electromagnet (50), a load cell (60) configured to provide a measure of the force acting on the induction electromagnet (50) due to the interaction of the magnetic fields of the disk (40) and the induction electromagnet (50) and provides a measure of the torque generated by the rotating shaft (30) of the rotating machine (20), a speed sensor (70) configured to provide a measure of the rotational speed of the rotating machine's shaft (30) and a base (80) that serves to support the rotating machine (20) fitted with the first portion (10a) and the induction electromagnet (50), load cell (60) and the speed sensor (70).
