Study of magneto-elastic torque meter for power steering system

Permanent magnets and magnetic field sensors are widely used in the automotive industry for the detection of the rotational speed of a gear or the torque measurement of gearbox shafts, vehicle axles, and electric motors. For instance, the action of a driving wheel can modify a magnetic pattern encoded in a transmission shaft. Magnetic sensors positioned around the shaft can detect the stress applied on the driving wheel. This is what we call a magneto-elastic torque meter. It provides the signal for the operation of the power steering system. In this project, a student will develop a model to study the performance of this system to help fabricate a competitive, highly sensitive and reliable magneto-elastic torque meter. Torque monitoring is very important for real-time control and fault diagnosis of a variety of mechanical equipment, such as the rotation of shafts in many things like pumps, rotational cutting equipment, gearbox shafts, vehicle axles, and electric motors. The research on magnetic field detection could also find potential applications in the detection of magnetic anomalies, geoprospection, security and biomedical imagin
