Claim:
1. An electromechanical apparatus comprising: a motor comprising an input structured to receive input power; and an electronic circuit structured to receive alternating current power and to condition said alternating current power and to output said conditioned power as the input power to said motor, wherein conditioning said alternating current power comprises at least one of limiting a magnitude of a current spike in said alternating current power and limiting a magnitude of a voltage spike in said alternating current power, wherein said electronic circuit comprises a current sensor structured to sense current of said alternating current power and a first detector structured to detect the current spike in said alternating current power from said sensed current and responsively limit the magnitude of said current spike of said alternating current power, and wherein said electronic circuit comprises a voltage sensor structured to sense voltage of said alternating current power, a second detector structured to detect the voltage spike in said alternating current power from said sensed voltage and responsively limit the magnitude of said voltage spike of said alternating current power, a first filter structured to filter current of the alternating current power, and a second filter structured to filter voltage of the alternating current power.
