Abstract
An electrical damping system provides damping over a wide range of frequencies including high frequencies. The system includes a resistance in parallel with an electric motor or series connected resistance and capacitance in parallel with the electric motor. In another embodiment, an electrical damping system is provided for a motor having a delta or wye motor winding configuration.
Claims7
A system for use in a haptic display for providing haptic feedback to a user comprising:
- a motor having a pair of leads;
- an electrical damping system including an electrical resistance connect across the leads so as to be in parallel with the motor;
- and
- a user interface coupled to the motor to provide haptic feedback to the user.
