CPC G06F 3/03543 (2013.01) [G06F 3/016 (2013.01); G06F 3/0485 (2013.01); G06F 3/167 (2013.01); G06F 2203/04806 (2013.01)] | 18 Claims |
1. A computer mouse comprising:
a scroll wheel assembly that comprises a scroll wheel rotatable about a scroll wheel axis;
a motor assembly that comprises a rotor aligned with the scroll wheel axis and operatively coupled to the scroll wheel, wherein the motor assembly comprises a brushless DC motor; and
motor control circuitry for control of the brushless DC motor, wherein the motor control circuitry senses a stall condition as input responsive to application of force to the scroll wheel that overcomes a torque of the brushless DC motor, wherein the motor control circuitry controls power to the brushless DC motor responsive to a sense of the stall condition to reduce risk of overheating, and wherein the motor control circuitry comprises a haptic feedback mode to generate haptic feedback via the scroll wheel via application of force to the rotor by the brushless DC motor.
