Abstract
An assembly is presented that can be used in an electric fireplace for providing rotational motion. The assembly can be used to drive an auxiliary axle with extensions to simulate a flickering flame. The assembly may include a direct current (DC) motor to create an initial rotational motion about an input axle at an input rate. The DC motor may be driven by a variable electric voltage that is variable. The assembly also includes a transmission to convert the rotational motion from the input axle at the input rate to an output axle at an output rate. The transmission uses pulleys, belts, and optionally gears to convert the rotational motion from the input rate to the output rate.
