<p>In an electric single-phase motor having a starting circuit, which in connection with an auxiliary winding (2) produces a switching from a starting condition to a running condition when the number of revolutions per minute of the motor during the starting procedure has reached a predetermined value, the starting circuit (5-9) is so designed that after the switching from the starting condition to the running condition it cannot re-establish the starting condition until the feed voltage of the motor has been switched off. Hereby, damages, e.g. destroying of component parts, are avoided, which could otherwise occur if the starting condition is re- established during running, e.g. by an overloading of the motor. <IMAGE></p> |
