Starting device for a single-phase motor with starting and running windings, which is provided in the starting branch with a resistance with essentially positive temperature coefficient (CTP resistance) and characterized in that the characteristic of the CTP resistance is composed of a branch that runs almost horizontally until the maximum value to be expected from the ambient temperature of the CTP resistor has been slightly exceeded, then climbing steeply.
