  • Abstract
    Magnetic noise in synchronous machines is shown to be of two principal kinds. One is a vibration in the tooth frequency range which usually occurs whether load is present or not; the other has twice line frequency and is dependent on load current. The vibrating part of the structure is usually the stator but may be the rotor and in nearly all cases of troublesome noise mechanical resonance is present. Some measurements of vibration on noisy machines are given.
