Hybrid boasts power, range
VIA Motors E-REV Powertrain is said to deliver better mileage than a Prius with the power of a pickup. Company engineers take us through some of the finer details on the drive train for their series of extended range electric trucks, vans, and SUVs, which reportedly deliver over 400 hp and 100 mpg.

Online wind-energy tools
The Dept. of Energy has two new online tools to help evaluate the viability of wind turbines installed near homes, businesses, schools, and hospitals. The Distributed Wind Site Analysis Tool (http://dsat.cadmusgroup.com) and Distributed Wind Policy Comparison Tool (www.eformativeoptions.com/dwpolicytool) use location and terrain information, predict energy output, and identify site-specific factors such as zoning and permitting costs and interconnection fees.
Energy savings estimator
Siemens Drive Technologies Div. has an online Energy Savings Estimator that lets users of drives, motors, couplings, and gearboxes estimate potential energy savings across the entire drive train. Given data on the application, horsepower, motor speeds, and gearbox reduction ratios, the Estimator evaluates potential savings and ROI of the recommended upgrade.

Power transmission for wind turbines
Altra Wind Technology's new Website, www.AltraWind.com, covers power transmission and motion control in wind turbines. Sections include rotor, yaw, and blade-pitch brakes, shaft-locking devices, high-speed shaft couplings, and access hatch actuators. Each offers technical details to improve efficiency, productivity, safety, and reliability.
Groschopp's new Website (www.groschopp.com) lets users precisely size fractional-hp motors and gearmotors. Motor Match is based on the company's STP Calculator, where users enter two of three performance parameters (speed, torque, and power) along with motor type, gearbox type (if desired), and voltage. The software evaluates and matches desired performance to the motor size and specs from more than 4,200 products in the site's database.
Addressing insulation challenges for hybrids and EVs
Fabrico's on-line forum (www.fabricoforum.com) discusses electrical insulation challenges when designing high-performance motors for hybrid and electric vehicles, such as excessive heat, high voltage, and EMI/RFI interference. The FabricoForum is an open dialog where design engineers interested in materials technology and bonding and sealing topics can read opinions and weigh-in on discussions.
