Phase angle measurement device between the resultable electric drive force and the electric drive force of the main harmonic magnetic field in the air gap of the industrial industrial engine

The article presents the results a device for measuring the phase angle between the resulting electromotive force and the electromotive force of the main harmonic magnetic field in the air gap of an asynchronous motor for general industrial use. Expanding the scope of the rotor position sensor in the form of a rectangular frame and the sensor of the main harmonic component of the field in the form of a sinusoidal frame, i.e. to measure the phase shift angle between the resulting electromotive force and the electromotive force of the main harmonic magnetic field in the air gap of an asynchronous motor for general industrial use.
