Abstract :
The chattering of an electromagnetic contactor which may occur when, for example, an induction motor is started direct to line, is studied. Considerations relating to the attractive force of the contactor indicate how a critical voltage may be calculated at which chattering will occur. It is shown that the theoretical voltage obtained this way, is in close agreement with the corresponding measured figure.
