This paper describes the relationship between the character of electromagnetic force waves in air-gap of the three-phase induction motors and the parameters of the electromagnetic design of the motors. A special attention is paid to the stator—rotor slot number combination, and frequencies of the electromagnetic force waves. The frequencies of electromagnetic force waves of two motors are calculated. A comparison is made between the calculated resultants and measured zoom spectra,and the close relationship between...

This paper describes the relationship between the character of electromagnetic force waves in air-gap of the three-phase induction motors and the parameters of the electromagnetic design of the motors. A special attention is paid to the stator—rotor slot number combination, and frequencies of the electromagnetic force waves. The frequencies of electromagnetic force waves of two motors are calculated. A comparison is made between the calculated resultants and measured zoom spectra,and the close relationship between them is relatively comfirmed.
