Latest Patents

Carlton’s recent patent work addresses modular resistor grids and closed-loop control for resistive braking.

“Modular resistor grid to achieve ‘black box’ resistance” describes interchangeable resistor-grid assemblies designed to provide a target electrical resistance using plates of different thicknesses and quantities. The assemblies can couple to a resistive braking system, offering alternative configurations while maintaining the specified resistance.

“Closed loop control of resistive braking based on temperature” describes a system that senses a condition indicating the temperature of a resistor element. A processing circuit determines the electric drive machine’s speed and the resistor element’s temperature during braking. When the temperature meets a threshold, the system calculates a maximum resistive braking speed and applies it to the machine’s governor to help prevent the machine from exceeding that limit.
