Diagnostics of rod rupture in the cell of an asynchronous-motor rotor

Spatial harmonic analysis of the internal and external magnetic fields of an asynchronous motor in rod rupture in the rotor cell permits the creation of a simple and reliable device for technological monitoring of the quality of rotor filling. The device has been installed at the Elektrotyazhmash plant (Khar'kov) in the form of a teststand used in the mass production of the DAV-71 motor.
