Brakes for high-speed SCARA robots and more

Precise positioning of semi-conductor wafers during SCARA assembly operations requires instantaneous braking and holding power while minimizing heat in the system. The latest compact and slender Miki Pulley BXR-LE brake models provide the needed, perfectly controlled braking in a confined area of the system using minimal power. The braking response and holding power of this power-off engaged brake makes it ideal for this and other high-speed applications. The BXR-LE brake uses 24 VDC for a split second to overcome compression spring inertia to open the brake, then consumes only 7 VDC by utilizing the BEM power control module.

Trade group warns about dangers, illegality of using E15 fuel blends in power equipment, small-engine products

A new online survey conducted by Harris Interactive on behalf of the Outdoor Power Equipment Institute (OPEI), the international trade association representing 100 small-engine, utility vehicle, and outdoor power equipment manufacturers and suppliers, finds that U.S. consumers are ill-prepared for the introduction of higher ethanol fuel blends.

The EPA has approved the introduction of some mid-level ethanol blends (E15, E30, E85) for use in a small, subset of automobiles in an effort to comply with the federal renewable fuel mandate; the problem is that these higher ethanol fuel blends may be dispensed alongside current fuels, but they are illegal and risky to use in hundreds of millions of small-engine products and applications.

E15 warning label approved by EPA.

 

 

This includes small-engine products, such as mowers, garden tractors, chain saws, boats, snow throwers, trimmers, UTVs, power washers, blowers, chippers, grinders, generators, jaws of life, concrete saws, and other compact construction equipment, as well as small-engine applications such as water pumps and irrigation systems.

As far back as 2009, the Outdoor Power Equipment Institute (OPEI) announced that it had serious concerns with a premature rush to 15 percent ethanol (E15) or other mid-level fuel blends as being suggested by pro-ethanol producers.

"Without a formal waiver process through the Environmental Protection Agency (EPA), and a continued misinterpretation of test results from a recent Department of Energy (DOE) report, introducing E15 and higher fuels to the marketplace for existing equipment poses serious risks to American consumers and businesses," the organization said in a press release.

"The DOE report, in fact, indicates that mid-level ethanol fuels could damage millions of forestry, lawn and garden, and other small-engine products currently housed in consumers' garages, boat slips, warehouses, or being used by small businesses. Higher ethanol blends can cause performance irregularities and pose substantial safety and environmental hazards." (Read the release here).

The study, conducted on behalf of OPEI from July 31 to August 2, 2013, surveyed 2,040 U.S. adults ages 18 and older about their fuel-buying behavior and fuel awareness at gas stations.

Key survey findings

• The vast majority of Americans (71 percent) are "not at all sure" if it is illegal or legal to put high-level ethanol gas (i.e., anything higher than 10 percent ethanol) into engines such as those in boats, mowers, chain saws, snow mobiles, generators, and other engine products.
• Nearly two-thirds (64 percent) of Americans say they assume that any gas sold at the gas station is safe for all of their cars, as well as boats, mowers, chain saws, snow mobiles, generators, and other engine products.
• For Americans who drive up to the fuel pump, price is overwhelmingly the number one thing they notice (91 percent). Whether the pump accepts credit cards (64 percent) and the octane rating (55 percent) come in second and third place. Only a quarter (25 percent) of these Americans notices the ethanol content.
• Seven in 10 (71 percent) Americans say they use the least expensive grade of gasoline whenever possible.

"Obviously, the ethanol survey responses are troubling to the outdoor power equipment industry since our products are designed and warranted to run only on 10 percent or less ethanol blended fuel. The data shows us that consumers are unprepared for the rollout of higher ethanol blended fuels at today's gas stations, and the potential for misfueling is high," said Kris Kiser, president and CEO of OPEI.

According to Kiser, "Many consumers are determined to buy the least expensive gasoline, while they still assume that the same fuel can go in their car as well as their mower, chain saw, or generator. This points to a huge awareness gap and dire need for education."

To protect current owners and future purchasers of small engines, UTVs, and outdoor power equipment, OPEI will be launching an ethanol education and consumer protection campaign at the 2013 GIE+EXPO (Oct.24-25), the annual green industry and equipment exposition, to educate consumers about the variety of fuels available at the pump, and how to identify the right fuel for their outdoor power equipment.

About the Survey
This survey was conducted online within the United States between July 31-August 2, 2013, among 2,040 adults ages 18 and older by Harris Interactive on behalf of OPEI via its Quick Query omnibus product. This online survey is not based on a probability sample, and therefore no estimate of theoretical sampling error can be calculated.
