Title: Christopher A. Nelson: Innovator in Cooling Systems
Introduction
Christopher A. Nelson is a notable inventor based in Bloomington, MN (US). He has made significant contributions to the field of cooling systems, particularly in the automotive industry. With a total of 3 patents to his name, Nelson's work focuses on enhancing the efficiency and effectiveness of cooling mechanisms in vehicles.
Latest Patents
One of his latest patents is a Brushless DC ring motor cooling system. This innovative method operates a cooling fan in a vehicle's cooling system by determining the required speed of the fan. The system provides first and second signals to a motor controller connected to the motor, which drives the cooling fan. The first signal coarsely controls the motor's rotational speed by adjusting the voltage level, while the second signal finely controls the speed through pulse width modulation. This ensures that the cooling fan operates at the necessary speed for optimal performance.
Another patent by Nelson also pertains to a Brushless DC ring motor cooling system. This design includes a shroud that can be attached to a fixed portion of the vehicle. A stator assembly for the brushless DC ring motor is mounted on the shroud, with a cooling fan piloted on the stator assembly. The fan features a ring that supports multiple blades, effectively sweeping an area inside the shroud. The rotor assembly confronts the stator assembly around its outer diameter, and the entire system is controlled by an electronic controller to provide appropriate cooling for the vehicle.
