Abstract

The electronic acquisition chain of a rotating-coil magnetometer is analyzed to identify electromagnetic noise sources and the effective noise floor of the acquisition. This allows to optimize the system, and the layout and the support of the induction coils for the intended application. The influence of a built-in motor drive unit on the results is studied, in order to establish the minimum distance between the motor and the induction coils to avoid detrimental effects on the measurement accuracy. Two electronically commutated (EC) motors of different power ratings are studied.
