In electrical and safety engineering, hazardous locations (HazLoc, pronounced haz·lōk) are places where fire or explosion hazards may exist. Sources of such hazards include gases, vapors, dust, fibers, and flyings, which are combustible or flammable. Electrical equipment installed in such locations can provide an ignition source, due to ...
There was also a basic bus, with an inline-4 inclined 1.8 carburetor engine. The 1.8 carb motor was a Golf-derived motor, fitted into the bus like an inline-4 diesel in a T3. Called the "Volksie bus", it was a basic bus, with steel 15" rims, single round headlights, steel wrap-around bumpers, and with no aircon or PAS.
Insulation system. The electrical insulation system for wires used in generators, electric motors, transformers, and other wire-wound electrical components is divided into different classes by temperature and temperature rise. The electrical insulation system is sometimes referred to as insulation class or thermal classification.
An operating temperature is the allowable temperature range of the local ambient environment at which an electrical or mechanical device operates. The device will operate effectively within a specified temperature range which varies based on the device function and application context, and ranges from the minimum operating temperature to the maximum operating temperature (or peak operating ...
Model rocket motor classification. Motors for model rockets [1] and high-powered rockets [2] (together, consumer rockets) are classified by total impulse into a set of letter-designated ranges, from ⅛ A up to O. The total impulse is the integral of the thrust over burn time. Where is the burn time in seconds, is the instantaneous thrust in ...
A simple homemade phase converter. A rotary phase converter, abbreviated RPC, is an electrical machine that converts power from one polyphase system to another, converting through rotary motion. Typically, single-phase electric power is used to produce three-phase electric power locally to run three-phase loads in premises where only single ...
The Boyce MotoMeter was patented in 1912, and was used in automobiles to show the temperature of the radiator. From then through the late 1920s, the Boyce MotoMeter Company in Long Island City , New York, founded in 1912 by the German immigrant Hermann Schlaich , manufactured different models which varied in size and design.
Fractional-horsepower motor. A fractional-horsepower motor (FHP) is an electric motor with a rated output power of less than one horsepower (745.7 W) (the term 'fractional' indicates less than one unit). There is no defined minimum output, however, it is generally accepted that a motor with a frame size of less than 35mm square can be referred ...
