First Claim
Patent Images
1. A fader apparatus comprising:
- a fader control knob directly attached to a rotor of a non-contact motor, wherein the rotor surrounds a stator of the non-contact motor, and wherein the non-contact motor is a three-phase, direct current electric motor;
a sensor system configured to detect a rotational position of the rotor; and
control circuitry configured to cause a fade effect in accordance with the detected rotational position of the rotor,wherein the fader control knob is configured to move along one or more axes, wherein a position of the fader control knob along each of the one or more axes is assigned at least one audio function, and wherein the stator is moveable to achieve the at least one audio function.

Abstract
A rotary fader apparatus includes a fader control knob that is directly attached to the rotor of a non-contact electrical motor. The apparatus may produce a fade effect based on the rotational position of the fader control knob and may be automated through signals to the motor. Such a rotary fader apparatus may be used, for example, in audio mixing applications to provide automated or manual rotary control of track fading. The motor may also be used to alter the feel of the movement of the fader control knob and/or provide tactile feedback in response to mixing parameters or signal properties.
