A hub dynamo is a small electrical generator built into the front hub of a bicycle wheel that is usually used to power lights. Often the hub "dynamo" is not actually a dynamo, which creates DC, but a low-power magneto that creates AC. Most modern hub dynamos are regulated to 3 watts at 6 volts, although some will drive up to 6 watts at 12 volts.
Small two-stroke, bolt-on gasoline bike motors and adapter kits for bicycles had a brief surge in popularity in the late 1960s and early 1970s in the United States and Canada. These engine kits were designed or marketed by both small and large companies, including Bike Bug, Tas Spitz, and even Sears , which sold the Free Spirit , and Little ...
A motor–generator (an MG set) is a device for converting electrical power to another form. Motor–generator sets are used to convert frequency, voltage, or phase of power. They may also be used to isolate electrical loads from the electrical power supply line.
A signal generator is one of a class of electronic devices that generates electrical signals with set properties of amplitude, frequency, and wave shape. These generated signals are used as a stimulus for electronic measurements, typically used in designing, testing, troubleshooting, and repairing electronic or electroacoustic devices, though it often has artistic uses as well.
Tidalforce Electric Bicycle. The Tidalforce Electric Bicycle was an electric bicycle manufactured by Wavecrest Labs from 2003 until the company went out of business in 2006. All models of Wavecrest Tidalforce electric bikes have a 36 volt electric hub motor built into the rear wheel hub and a 36 volt battery pack built into the front wheel hub.
"Dynamo Electric Machine" (end view, partly section, U.S. patent 284,110) A dynamo is an electrical generator that creates direct current using a commutator.Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current ...
A magnetohydrodynamic generator (MHD generator) is a magnetohydrodynamic converter that transforms thermal energy and kinetic energy directly into electricity.An MHD generator, like a conventional generator, relies on moving a conductor through a magnetic field to generate electric current.
The AN/URM-25 was part of a series of vacuum tube-based signal generators built for the U.S. military in the early Cold War-era.. Today they are collected and used by vintage amateur radio and antique radio enthusiasts who say they provide reasonably high accuracy and stability for a low cost, with build quality reflecting tough military construction requirements and standards.
