Abstract
A motor drive system and method for driving a cast bell or similar object, comprising a motor and cam switches driven by the motor which operate relays in accordance with a duration angle and a start angle respectively, the circuit of the drive system supplying power to normally provide drive energy to the bell when it is swinging through the duration angle, and to provide power to the bell following system initiation as long as the bell is within the start angle. The start angle is set to be greater than the duration angle so as to optimize steady state power delivery while ensuring power delivery at the time of initial system energization.
