Abstract
Method for controlling the operation of a pump driven by an electric motor and controlled by a controller, according to which an electronic control module (ECM) sends, to the controller, a PWM (Pulse Width Modulation) control signal having a duty cycle that varies as a function of the desired operating conditions for the pump and according to which the controller acts on the electric motor to apply said operating conditions to the pump.
