Abstract
Embodiments described here concern a method to control a direct current motor powered by an alternating supply voltage, which provides to detect the instant of the zero-crossing of the supply voltage and to selectively activate a switch device to power the motor by the positive half-waves of the supply voltage in order to make it rotate in one sense, and by the negative half-waves in order to make it rotate in the opposite sense. The disclosure also concerns a control circuit for the motor.
