Latest Patents
One of Buchwald's latest patents is a "Multiple chopper speed control system for compound motor." This system is designed for battery-powered vehicles, where the series winding and the shunt winding of the motor are magnetically linked for energy transfer. The system includes a first current switch connected in series with the series winding and armature, and a second current switch connected in series with the shunt winding. A digitally-implemented speed control system responds to speed selection settings to operate the switches intermittently, optimizing performance across different speed ranges.
Another significant patent is the "Brush wear indicator." This device features a first contactor and a second contactor that moves relative to the first to connect an electrical circuit to an indicator. The second contactor is held open by a coil spring, which allows a brush to move toward a commutator. As the brush wears down to a preselected length, the coil spring allows the second contactor to close, providing a clear indication of brush wear.
