Wheel may fly high
, a flywheel energy system, also known as an electromechanical battery, uses an electric motor to spin a wheel or rotor to store energy. The energy stored in the wheel then drives an electric generator which, in turn, powers an electrical load. The resistance of the load, reflected back to the wheel, gradually

Hybrid Drives for Construction Equipment
for recharging capacitors. When applications call for more traction, the electric drive functions as a motor and provides power for added torque and faster take-off. Targeted for material-handling vehicles, Dana is evaluating three and four-speed versions of the TE-15HX transmission with estimated

Off-Road Electric Drives Gain Traction
(volvo.com), unveiled a preproduction prototype of its L220F Hybrid wheel loader. Company officials say it offers more power, better performance, and a 10% reduction in fuel consumption, compared with current versions. The heart of the parallel-hybrid system is an electric motor called an Integrated

Linear actuators get a servo look
, friction, wear, cogging, resonance, and so forth gives direct-drive linear actuators agility and lets them be easily controlled. The most recent advance in direct- drive linear actuators is called a tubular linear actuator. It evolved from linear-motor technology. A conventional way to describe
