The EPT electric powertrain testers from D&V Electronics for the HV/EV market are used for endurance, laboratory, and end-of-line production testing of integrated motor-generators and control systems.

The EPT electric powertrain testers from D&V Electronics for the HV/EV market are used for endurance, laboratory, and end-of-line production testing of integrated motor-generators and control systems. Engine simulation tests will also examine operation of the motor-generator with pulsation of the engine’s compression stroke. Endurance testing inside a thermal chamber is offered, as are oil and water/glycol conditioning systems. Hybrid motor-generator performance testers automatically measure motoring and generating characteristics, including a performance curve plotting torque, current, voltage, speed, power, efficiency, resolver angle, back EMF, amplitude and phase imbalance, sound, vibration, and resistance. The X-3 software platform is XML-based and allows development of complete tester software packages, with utilities for producing the test specification database, user interface, reporting software, and statistical utilities. Test procedures can be developed with a flow chart programming utility.

Patchwork3D visualization software from Lumiscaphe allows operations to be executed in real time, with results seen in 3-D and real time on the designer’s screen.

Patchwork3D visualization software from Lumiscaphe allows operations to be executed in real time, with results seen in 3-D and real time on the designer’s screen. This enables the designer to work faster and to review and present projects smoothly. High-quality rendering also provides accurate visualization when walking through a scene in 3-D, even for complex scenes loaded with texture. The software enables engineers to produce work free of errors, thus reducing time to market. It eliminates the need for physical mockups used for project reviews. It also permits companies to test new materials quickly and determine whether they will perform properly on complex surfaces. An unwrapping module allows the flattening, in 2-D, of complex 3-D surfaces to assist proper material cutting for application on 3-D surfaces and optimize the use of material.

Using the same technology as flat-blade designs, ADM21 has developed a wireless heat-treated wiper.

Using the same technology as flat-blade designs, ADM21 has developed a wireless heat-treated wiper. Powered by micro-solar panels, the company’s TFT blade consumes the sun’s UV rays and translates that energy into heating the windshield. A traditional washer system needs to be refilled, whereas a heated blade requires no maintenance or supervision since it will defrost the window. This means the driver no longer has to scrape ice off the windshield or worry about whether the washer tank is full.

Shilla Industrial’s clutch coil for a switchable water pump eliminates unnecessary water pump operation to reduce fuel consumption.

Shilla Industrial’s clutch coil for a switchable coolant pump eliminates unnecessary pump operation to reduce fuel consumption. The clutch coil is installed in the coolant pump to disable operation during idling up. By only operating during the times required by the engine, preheating time is reduced and annual fuel usage is lowered by 2%, claims the company.

The mid-frequency dc (MFDC) butt-welding system and process controller from Hess Industries is designed for passenger-car and heavy-duty-truck rim manufacturing.

The mid-frequency dc (MFDC) butt-welding system and process controller from Hess Industries is designed for passenger-car and heavy-duty-truck rim manufacturing. The company’s butt-welding technology offers improved power factor, enhanced process control, smaller transformer package, and lower support costs. The primary benefit of the technology is a reduction in energy consumption. User test data indicates that the power reduction between traditional three-phase dc and the MFDC solution can be as high as 59% per weld cycle and as high as 75% between ac and MFDC, according to the company. Depending on power costs in a given area, wheel manufacturers could see energy cost savings of hundreds of thousands of dollars a year per line.
