A large U.S. manufacturer was facing increased costs due to energy loss and man-hours spent tightening contact lugs. Sixteen three-phase motors averaged 480 HP at 30 amps, with typical energy costs at $.065 per kilowatt-hour. The electric contact lugs coming loose through vibration and harmonic loosening were accounting for an energy loss of about 13%, and were consuming as much as eight man hours per week to re-tighten them. The cost in dollars was calculated to be approximately $250 per motor, per year. An Applied®/Loctite® plant assessment discovered the efficiency problem and through a one-time maintenance program, the plant now saves a total of $4,000 each year.
