Abstract
The usage of magnetic sensors is increasing steadily in the field of electric drives. Above all magnetoresistive (MR) sensors are experiencing a significant increase in applications in motion control and power electronics systems, not only in the industrial and automotive fields, but also in aerospace applications. MR sensors are not only used for measuring rotational and linear motion, but also for non-contact switching applications and furthermore for highly dynamic current measurement. This is largely the result of increasingly complex demands on the sensors for high performance electric drives [1]. Sensors must not only be accurate and dynamic, but must also be robust under difficult operating conditions and exhibit very high reliability. Recent developments, such as the trend to electro-mobility, are generating additional demands, with respect to compact dimensions and energy efficient operation. This combination of demands is leading to the more intensive use of magnetic sensor principles, compared to optical, inductive or capacitive principles.
