Abstract

A floating magnetic rotor is synchronized to a rotating magnetic field in the developed pump. We cannot measure or calculate the magnetic torque using a general measurement method because the angle theta (θ) represents the unknown factor between the magnetic field and the magnetic moment on the magnetic rotor. We have converted the relationship between the rotating magnetic field and the rotation of the magnetic rotor to an electrical signal using Faraday's law. Converted signals have a phase difference that is converted to the angle theta (θ) in the magnetic torque. This has allowed us to calculate the magnetic torque.
