Are ball splines right for your application?
Thomson Industries says ball splines are making a comeback, because more opportunities for automation bring more axes of motion to machinery, and pre-packaged solutions may not have the flexibility you require. But are ball splines the right choice for your design needs? They have the unique capability of integrating rotary and linear motion on a single shaft.

Intro to motor constants for fractional horsepower gearmotors
According to motor expert Bodine Electric, "Motor constants are needed to calculate permanent magnet DC (PMDC) or brushless DC (BLDC or EC) motor specifications and ratings, or to match the motor properly to an amplifier." You need the constants to predict the motor's performance with changing variables, such as different input voltages or different loads. This app note explains what the constants are, how they are derived. and how to use them. Very useful.

Ward's 10 Best Engines of 2013 announced: no hybrids, all-electrics, or diesels
Ward's 10 Best Engines have been announced for 2013. For the first time in seven years, the list is comprised entirely of gasoline-powered engines, with no hybrid, all-electric, or diesel powertrains to be found.
While this result might seem to go against the grain of the industry's push into alternative fuels and propulsion systems, WardsAuto editors who judged the awards see the list as proof there is significant innovation still happening in the development of traditional gasoline engines, making them more fuel-efficient and refined than ever.
"We're always excited to see the advancements being made in hybrids and all-electric vehicles," says Drew Winter, editor-in-chief of WardsAuto World magazine. "But there are still significant barriers for the average consumer to look past when considering these vehicles. The cost for most of them remains high, and the driving ranges of the battery electric vehicles will have to be extended to meet the needs of most people."
Instead, the WardsAuto judges found significant innovations in fuel efficiency and overall refinement in the traditional gasoline engines that power the majority of vehicles that will be on the road for the foreseeable future.
Now in its 19th year, the Ward's 10 Best Engines competition recognizes the latest powertrain technologies that are affordable to most consumers, boost horsepower and torque, are highly efficient, sound appealing, and pair up well with their respective vehicles. This year's winners (and the vehicles tested) are:
- 3.0L TFSI Supercharged DOHC V-6 (Audi S5)
- 2.0L N20 Turbocharged DOHC I-4 (BMW 328i)
- 3.0L N55 Turbocharged DOHC I-6 (BMW 135is coupe)
- 3.6L Pentastar DOHC V-6 (Ram 1500)
- 2.0L EcoBoost DOHC I-4 (Ford Focus ST/Taurus)
- 5.8L Supercharged DOHC V-8 (Ford Shelby GT500)
- 2.0L Turbocharged DOHC I-4 (Cadillac ATS)
- 2.4L DOHC I-4 (Honda Accord Sport)
- 3.5L SOHC V-6 (Honda Accord)
- 2.0L FA DOHC H-4 Boxer (Subaru BRZ)
WardsAuto editors chose the winners after spending October through early December driving 40 vehicles in their routine daily commutes around metro Detroit. Editors scored each engine based on power; technology; observed fuel economy; and noise, vibration, and harshness characteristics. There is no instrumented testing. To be eligible, each engine must be available in a regular-production U.S.-specification model on sale no later than first-quarter 2013, in a vehicle with a base price below $55,000. Winners from the 2012 competition were automatically eligible and evaluated against the new engines for 2013.
"The world's automakers are showing no signs in slowing down when it comes to making gasoline engines the best choice for today's and tomorrow's drivers," Winter says. With new technologies such as "stop-start" -- which shuts down the engine when a vehicle comes to a stop or idles -- automotive engineers are proving they have no shortage of tricks up their sleeves for reducing fuel consumption and cost of ownership."
