  • Fuel Efficiency Improvements from Lean, Stratified Combustion with a Solenoid Injector (.pdf)
    actuator and high-. voltage electronic driver circuits. The resulting injector. The requirements on the Multec 20 actuator are more. has been designated the Multec 20. demanding in terms of transient response and force than. for solenoid multi-hole injectors. Yet, the target of. The Multec 20
  • High-Performance Thermoplastics for Sensors and Actuators Under the Hood
    Sensors and actuators used in the engine compartment are being exposed to higher temperatures, more aggressive media and more extreme thermomechanical loads than ever before. These combined stresses are imposing requirements that increasingly exceed the capabilities of the polymers traditionally
  • How Some Supervisory and Leakage Currents Can Affect Today's Low-Power Solenoid Valves
    In process plants worldwide, low-power solenoid valves are used as pilot valves to open. and close larger ball or butterfly valves, or on control valves for fail-safe air release if there's. a loss of power or air. They work by pressurizing or depressurizing associated actuators. þÿ Current
  • 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
  • Pulse and Hold Power Management
    Acro Associates' solenoid pinch valves employ a spring-loaded linear actuator to control motion of the pinching surfaces. Most linear solenoid actuators are closing-the-air-gap devices, where the force characteristics vary substantially throughout the stroke. Generally, actuators are designed so
  • Voice Coil Motors
    Voice coil motors offer excellent control characteristics where linear actuation is required over short distances with electronic control systems. Comparison of the force characteristics vs displacement, and vs current, for voice coil devices and solenoid actuators shows the difference between
  • Getting up to speed with wrap-spring clutch/brakes
    , repeatable, and independent of inertia or frictional load, provided the unit runs within its rated torque capacity. Conversely, start and stop times of a frictional clutch or brake (bottom) directly depend on load inertia and friction Machines that move loads to specified positions and hold them
  • Getting Up to Speed With Wrap-Spring Clutch/Brakes
    and stop times of a frictional clutch or brake (bottom) directly depend on load inertia and friction. Machines that move loads to specified positions and hold them within a few thousandths of an inch need highly controllable, precision brakes. Engineers typically spec friction brakes
