Novel Rotary Encoder with Multi-Axis Hall Sensors
2023 IEEE SENSORS, 2023 <p>We present a novel high-accuracy rotary magnetic sensor system composed of a two-track coded multi-pole magnet and a dual-spot multi-axes magnetic sensor. The novelty is the measurement of two orthogonal magnetic field components in each of the two sensing spots of the sensor, one associated with each magnet track.

Kinematical Smoothing of Rotary Axis near Singularity Point [PDF]
Materials Science Forum, 2016 This paper deals with singular configurations of a 5-axis machine tool in high speed milling which may lead to the appearance of large incoherent movements of rotary axes near singularity points. These movements generate slowdowns of the actual feedrate during the execution of the tool path, which affect quality and productivity.
