Abstract
A mechanism for compensating power to a motor or actuator. Compensation may counter the effects of changing voltage levels of power to the motor and varying temperatures at the motor. An output of a wave generator may be input to a comparator along with a level of voltage representing the temperatures and voltage levels. An output may be a power signal for driving the motor at a constant speed and/or torque which can increase a maintenance-free lifetime of the motor and actuator.
