Latest Patents

David Chapman holds a patent for a "Brushless DC motor control and methods of operating a fuel pump." This invention features a fuel filter assembly that incorporates a brushless DC motor and a control circuit. The system is designed to operate at a first rotational speed upon startup and switch to a second rotational speed when certain variables indicate that the filter assembly is filled with fuel. The initial rotational speed is set as a default when power is applied to the control circuit. If the filter assembly has been serviced, it must be primed before returning to normal operation. The first rotational speed is significantly higher than the second, which reduces the time required to prime the filter assembly. The control circuit monitors a variable corresponding to the torque necessary to drive the pump. When the pump is filled with air prior to priming, lower torque is required, resulting in lower current draw and power consumption at the brushless DC motor.
