    ...the turbine at about 65 mph. Gears connect the low-speed shaft to the high-speed shaft and increase the turbine's rotational speeds from about 30 to 60 rotations per minutes (rpm) to about 1200 to 1500 rpm. With upwind turbines, motor-powered yaw drives...
  • Low Light Cameras-Image
    Low Light Cameras - (152 companies)
    Low light cameras are a type of video camera with extreme photon sensitivity, and are excellent for recording in situations where only ambient levels of light are available. Common deployments include overnight surveillance and remote machine...
    Lead, Tin, and Low Melting Alloys - (120 companies)
    How to Select Lead, Tin, and Low Melting Alloys. Lead, tin, and low melting alloys are non-ferrous alloys that are easily meltable with relatively low melting temperatures. They are used in the manufacture of solders, semiconductors, batteries...
    RF Low Pass Filters - (98 companies)
    RF low pass filters pass signals from low frequencies and reject signals from high frequencies. Performance specifications include specified frequency, bandwidth, ripple, insertion loss, and voltage standing wave ratio. For RF low pass filters...
    Motor Controllers - (719 companies)
    ...load is overcome, they switch to a more efficient low-torque delta configuration. Computer-based motor controllers use many different types of buses and communication standards. Bus types include advanced technology attachment (ATA), peripheral...
    Active Low Pass Filters - (22 companies)
    Active low pass filters pass signals from low frequencies and reject signals from high frequencies. Low pass filters (LPF) pass signals from low frequencies and reject signals from high frequencies. Like other types of active filters, they use...
