Latest Patents
Towey's latest patents include the "Optimization of magnetizing current in linear induction motors" and the "Secondary positioning system for elevator car doors." The first patent addresses the optimization of magnetizing current generated in a linear induction motor that drives elevator car doors. This innovation allows for a low magnetizing current level during door operation modes that require less thrust, such as hold open and hold closed. Conversely, the current level is increased for modes requiring greater thrust, such as opening or closing. This optimization reduces overheating and enhances energy efficiency. The second patent introduces a secondary positioning system for elevator car doors, which utilizes three sensors aligned with multiple openings in a door hanger. This unique configuration enables the determination of fully closed, fully opened, and intermediate positions of the elevator car doors.
