Driving Auto Performance Through Lubricant Selection

Underhood temperatures are gradually rising as aerodynamics dictate tighter packaging and large engines are being replaced by smaller turbocharged and supercharged engines for improved fuel efficiency. With ambient temperatures under the hood exceeding 120 °C (248 °F), finding a lubricant that can withstand the high temperatures for an extended period of time is key.

Optimizing Drive Systems for Energy Savings

Energy savings are an extremely important topic in virtually every segment of industry today. In general, the largest consumer of power in a converting line or machine is the drive system. As energy costs continue to increase and energy conservation becomes a greater priority, are there technologies or methods that can be implemented to reduce the energy consumption on converting machinery?

Automation System Retrofit Transforms 175-Ton Hydraulic Forming Press

Southern Manufacturing Group (SMG) of Morrison, TN, makes automotive components and industrial valves. In 2012, the automation system for its 175-ton hydraulic forming press received electrical damage resulting from a lightning strike (Figure 1). Purchasing a new hydraulic forming press would be prohibitively expensive — in the range of hundreds of thousands of dollars. Therefore, SMG needed a company that could repair the forming press in a short timeframe to maintain its production schedule.

Severe-Environment Motors

Marathon Motors (Wausau, WI) introduced totally enclosed air-over (TEAO) cooling tower motors with Bearing Current Protection (BCP) using AEGIS® Shaft Grounding Rings. The NEMA Premium Severe-Duty motors feature BlueChip® cast iron construction for rigidity and reduced vibration. With internal and external epoxy paint, sealed bearings, T-drains in both end-shields for effective drainage, drive-end bearing isolators with shaft slingers, and fully gasketed conduit boxes (with lead separators), they are IP56-rated and built to withstand the harsh environments of cooling towers.

High-Torque Drives

Schneider Electric Motion USA (Marlborough, CT) offers Lexium MDrive NEMA size 23 drives with high-torque stepper motors as an alternative to standard motors. Closed loop performance of the drives eliminates possible motor stalling, and delivers continuous torque at low speeds. It eliminates tuning, and reduces heat and energy usage with variable current control. Various industry-standard communication protocols are available, including EtherNet/IP, ModbusTCP, Profinet, CANopen, and serial RS-422/485 with programmable motion control and pulse/direction input.

Actuator Control

The DCH Series actuator control from American Control Electronics (South Beloit, IL) combines an AC-to-DC switching power supply with a regenerative PWM drive to create an all-in-one solution. The control is suited for applications requiring control of 12 or 24 VDC motors when only 115 or 230 VAC power is available. With an isolated front end, this series is compatible with a 0-5 or 0-10 VDC analog from any PLC. With an 8-bit onboard microprocessor, the control can be customized in many applications to replace a PLC. The series also provides an alternative to using higher-voltage controls with the output voltage turned down, which results in current spikes. The control includes an industry-standard microprocessor used on popular PLCs. A modified option allows for linear positioning control of actuators to within 1/1000 of commanded stroke length with the use of feedback resistors. Standard variations include options for torque, cycling, or positioning control. Standard I/O is 1 analog and 4 digital, with custom configurations available.
