A linear motor is an electric motor that has had its stator and rotor "unrolled", thus, instead of producing a torque ( rotation ), it produces a linear force along its length. However, linear motors are not necessarily straight. Characteristically, a linear motor's active section has ends, whereas more conventional motors are arranged as a ...
A linear induction motor ( LIM) is an alternating current (AC), asynchronous linear motor that works by the same general principles as other induction motors but is typically designed to directly produce motion in a straight line. Characteristically, linear induction motors have a finite primary or secondary length, which generates end-effects ...
For a citation to appear in a footnote, it needs to be enclosed in "ref" tags. You can add these by typing <ref> at the front of the citation and </ref> at the end. . Alternatively you may notice above the edit box there is a row of "markup" formatting buttons which include a <ref></ref> button to the right—if you highlight your whole citation and then click this markup button, it will ...
Motor velocity constant, back EMF constant. is the motor velocity, or motor speed, [ 2] constant (not to be confused with kV, the symbol for kilovolt ), measured in revolutions per minute (RPM) per volt or radians per volt second, rad/V·s: [ 3] The rating of a brushless motor is the ratio of the motor's unloaded rotational speed (measured in ...

Electric generator. U.S. NRC image of a modern steam turbine generator (STG). In electricity generation, a generator[ 1] is a device that converts motion-based power ( potential and kinetic energy) or fuel-based power ( chemical energy) into electric power for use in an external circuit. Sources of mechanical energy include steam turbines, gas ...
A worker at a federal prison in California has died and investigators are examining whether he was exposed to fentanyl shortly before his death, three people familiar with the matter told The ...
A new artificial turf surface at the Oakland Athletics' temporary home in Sacramento, California, will have a hydration element because of summer heat at the open-air ballpark. “We think that ...
