A starting system for a single-phase induction motor is disclosed. The starting system includes a stator having a running coil (11) and a starting coil (12), a power source (F) which supplies current to the running coil (11) and the starting coil (12), a running switch (S1), and a starting switch (S2) connecting the running coil (11) and the starting coil (12) to the power source (F) when in a closed condition. The starting switch (S2) is changed to an open condition upon completion of the motor start, and a control unit (30), is supplied by the power source (F) and operatively connected to both the running switch (S1) and the starting switch (S2) in order to instruct the open and closed conditions. The control unit (30) is programmed to operate the running switch (S1) to cause a delay in the supply of the current supplied to the running coil (11) in relation to the supply of the current supplied to the starting coil (12) during the motor start, for a determined time interval, which is previously defined and considered from the zero-crossing moment of the current supplied to the stator.
