METHOD FOR COUNTING THE NUMBER OF REVOLUTIONS OF A BURR OF A COFFEE MILL AND APPLIANCE COMPRISING SUCH A MILL |
摘要 |
A method for counting the number of revolutions of a burr of a coffee mill driven in rotation by an electric motor. According to the method: at least one electrical parameter Pi of the motor that varies in proportion to the speed of said motor is measured in a regular time interval Ti; the speed Vi in each time interval Ti is calculated from the parameter Pi based on an experimentally obtained relation; and the number of revolutions Ni made by the burr in each time interval Ti is calculated from the speed Vi determined. |
