Abstract
A control system is disclosed for controlling the speed at which an electric motor drives a conveyor to move products through a conveyor oven. The system includes a temperature sensor configured to sense the temperature of the conveyor oven and a speed adjustment input for selecting a speed setting corresponding to a desired amount of heat to be transferred to the products that move through the conveyor oven. The system also includes a controller having temperature data storage capacity and programmable logic capability. The controller receives input signals from the temperature sensor and the speed adjustment input to perform operations on the stored temperature data and the input signals to provide an output signal to control the speed of the motor according to changes in the temperature of the conveyor oven
