Abstract
A ball accelerator mechanism employs one or more electromagnetic coils in combination with sensor elements to accelerate a rolling ball made of ferro-magnetic material. As a ball approaches the coil, it operates the sensor applying a DC current pulse to the coil. As the ball enters the coil, it is magnetically accelerated until it clears the sensor at which time the current is turned off. The length of the current pulse is thus a function of ball velocity. Preferably to maximize acceleration, the width of the coil is an integral multiple of the ball diameter.
