A piezoelectric motor or piezo motor is a type of electric motor based on the change in shape of a piezoelectric material when an electric field is applied, as a consequence of the converse piezoelectric effect. An electrical circuit makes acoustic or ultrasonic vibrations in the piezoelectric material, most often lead zirconate titanate and ...
The Ford River Rouge complex (commonly known as the Rouge complex, River Rouge, or The Rouge) is a Ford Motor Company automobile factory complex located in Dearborn, Michigan, along the River Rouge, upstream from its confluence with the Detroit River at Zug Island. Construction began in 1917, and when it was completed in 1928, it was the ...
A wound-rotor motor, also known as slip ring-rotor motor, is a type of induction motor where the rotor windings are connected through slip rings to external resistance. Adjusting the resistance allows control of the speed/torque characteristic of the motor. Wound-rotor motors can be started with low inrush current, by inserting high resistance ...
A vehicle outfitted for firefighting, specifically one outfitted to pump water. Many rural fire engines carry a reservoir of water to pump, and use drafting and water tenders to obtain further supply. Historically, an engine (" enjin " or other spellings) was any kind of machine, tool or "contrivance".
A slip ring (in electrical engineering terms) is a method of making an electrical connection through a rotating assembly. Formally, it is an electric transmission device that allows energy flow between two electrical rotating parts, such as in a motor . Slip rings on a hydroelectric generator; A - stationary spring-loaded graphite brushes,
Rocker arm. A rocker arm is a valvetrain component that typically transfers the motion of a pushrod in an overhead valve internal combustion engine to the corresponding intake/exhaust valve . Rocker arms in automobiles are typically made from stamped steel, or aluminum in higher-revving applications. Some rocker arms (called roller rockers ...
The shaded-pole motor is the original type of AC single-phase motor, dating back to at least as early as 1890. [ 1] 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 ...
BEIRUT (Reuters) -Lebanon's Hezbollah said early on Wednesday its senior commander Fuad Shukr had been in a building in the southern suburbs of Beirut when it was targeted by an Israeli strike ...
