  3. Hall effect sensor - Wikipedia

    en.wikipedia.org/wiki/Hall_effect_sensor

    Hall sensors may be utilized for contactless measurements of direct current in current transformers. In such a case the Hall sensor is mounted in a gap in the magnetic core around the current conductor. [24] As a result, the DC magnetic flux can be measured, and the DC in the conductor can be calculated.

  6. Planar Hall sensor - Wikipedia

    en.wikipedia.org/wiki/Planar_Hall_sensor

    The planar Hall sensor is a type of magnetic sensor based on the planar Hall effect of ferromagnetic materials. [1] [2] It measures the change in anisotropic magnetoresistance caused by an external magnetic field in the Hall geometry. As opposed to an ordinary Hall sensor, which measures field components perpendicular to the sensor plane, the ...

  7. Hall effect - Wikipedia

    en.wikipedia.org/wiki/Hall_effect

    In ferromagnetic materials (and paramagnetic materials in a magnetic field), the Hall resistivity includes an additional contribution, known as the anomalous Hall effect (or the extraordinary Hall effect), which depends directly on the magnetization of the material, and is often much larger than the ordinary Hall effect.

  8. Hall-effect thruster - Wikipedia

    en.wikipedia.org/wiki/Hall-effect_thruster

    6 kW Hall thruster in operation at the NASA Jet Propulsion Laboratory. In spacecraft propulsion, a Hall-effect thruster (HET) is a type of ion thruster in which the propellant is accelerated by an electric field. Hall-effect thrusters (based on the discovery by Edwin Hall) are sometimes referred to as Hall thrusters or Hall-current thrusters.

  9. Incremental encoder - Wikipedia

    en.wikipedia.org/wiki/Incremental_encoder

    Incremental encoders exhibit symmetry and phase errors due to sensor imperfections When moving at constant velocity, an ideal incremental encoder would output perfect square waves on A and B (i.e., the pulses would be exactly 180° wide and the duty cycle would be 50%) with a phase difference of exactly 90° between A and B signals.
