ABSTRACT:
In a method and device for monitoring the operation of a motor, the current drawn by the motor is sensed a preselected time after a peak of current is sensed. This sensed current is then compared to both a minimum and a maximum current threshold value to determine whether the sensed current is inside or outside the range of currents defined by the minimum and maximum current threshold values. The minimum and/or maximum current threshold values are dynamically adjusted as a function of the comparison.
