Electromechanical

Spot welding in factory automation

• Traditionally pneumatic actuation

• 10% of all energy used is for compressed air

• Electromechanical actuation give more than 90% energy saving

• SKF is the leading supplier for electromechanical actuators for spot welding

Application benefits

• Reduced energy consumption by more than 90%

• Faster welding cycle speeds than pneumatic

• Better quality through greater control of the process

• More flexibility in adapting to changes in the line

• Reduced maintenance cost

• Less noise

Energy saving - Factory automation

Pneumatic actuation of robots = 50,000 kWh

Electromechanical actuation of robots = 5,000 kWh

Saving per robot and year = 45,000 kWh

Potential saving in a welding line/year = 13,500,000 kWh

Corresponds to = 9,500 HMEC

HMEC = Household Monthly Energy Consumption

Automatic welding line per robot

Energy - Natural gas compressor

Application

•12,000 rpm, 12 MW centrifugal compressor

• Installed at Stagecoach, N.Y USA, natural gas pipeline facility

•Fitted with SKF Active Magnetic Bearings

•Reduced maintenance cost

•Reduced or eliminated lubrication system

Energy saving-Gas compressor

For a 12 MW Compressor running at 12,000 rpm

•Annual saving by using magnetic bearings is 700,000 kWh

•88% energy saving on the total compressor operation (compressor and motor)

•Corresponds to 500 HMEC

HMEC = Household Monthly Energy Consumption
