Method for starting a single-phase synchronous electric motor using permanent magnets with simple and cost-effective implementation, said method comprising a step of application of a control logic of the switch that provides a first and a second condition for switching on:
the first condition being verified when a detected counter electromotive force signal has the same sign as an electrical grid voltage signal;
the second condition being verified when said counter electromotive force signal has the same sign as its first derivative value. |
