Abstract
A method for controlling a pendulum angle of a bell, in particular a church bell, wherein a pendulum movement of said bell is powered by a pulsewise driven electrical motor, in particular an asynchronous motor, wherein during a first phase of a repetitive control cycle a powerpulse is supplied to said motor, and wherein, during a second phase of said control cycle where no power is supplied to said motor and which follows said first phase, a DC voltage is appied on said motor in order to generate a time signal indicating an actual time period for said pendulum movement, said time signal being compared with a predetermined time period for said pendulum movement in order to determine a correction value if said actual period is different from said predetermined time period. <IMAGE>
