Motor balanced active user interface assembly

摘要

An active user interface assembly includes a user interface (402), and one or more feedback motors (404,410) coupled to the user interface (402). The one or more feedback motors (404,410), when energized, supply a feedback force to the user interface (402) that opposes user interface movement. One of the feedback motors (404,410) is disposed such that its center of gravity is located at a position relative to the user interface (402) to mass balance the user interface (402) when it is in the null position. The configurations allow for the center of gravity of a feedback motor (404,410) to be positioned in a manner that alleviates the need for counterbalance weights.
