AC induction motors also use field coils on the stator, the current on the rotor being supplied by induction in a squirrel cage. For generators, the field current is smaller than the output current. [note 2] Accordingly, the field is mounted on the rotor and supplied through slip rings. The output current is taken from the stator, avoiding the ...
A shaded-pole motor is a motor, in which the auxiliary winding is composed of a copper ring or bar surrounding a portion of each pole to produce a weakly rotating magnetic field. [2] When single phase AC supply is applied to the stator winding, due to shading provided to the poles, a rotating magnetic field is generated.
Midland-Ross Co. was an American steel, aerospace products, electronics, and automobile components manufacturer which existed from 1894 to 1986. Founded as Parish & Bingham, a manufacturer of steel components for bicycles, streetcars , and horse-drawn wagons, it merged with the Detroit Pressed Steel Co. in 1923 to form the Midland Steel ...

A 2-horsepower (1.5 kW) engine, built in 1818 for pumping water at an Ayrshire quarry, continued to work for some time until a careless attendant allowed the heater to overheat. This experiment proved to the inventor that, owing to the low working pressure obtainable, the engine could only be adapted to low power for which there was, at that ...
An AC motor is an electric motor driven by an alternating current (AC). The AC motor commonly consists of two basic parts, an outside stator having coils supplied with alternating current to produce a rotating magnetic field, and an inside rotor attached to the output shaft producing a second rotating magnetic field. The rotor magnetic field ...
A 7.5 cm diameter dual voice coil from a subwoofer driver. A voice coil (consisting of a former, collar, and winding) is the coil of wire attached to the apex of a loudspeaker cone. It provides the motive force to the cone by the reaction of a magnetic field to the current passing through it.
[2] He was one of the first American drivers to complete a mile course in under one minute. [1] In 1906 he gave up racing to turn his attention full-time to automobile manufacturing. [1] Ross closed his steam car business in 1911 and focused on the manufacture of torpedo signals used by railroads.
