Early incarnations of the electric motor first appeared in the 1740s through the work of Scottish Benedictine monk and scientist, Andrew Gordon. Other scientists such as Michael Faraday and Joseph ...

The two most important electric motors are the ac induction motor and the permanent magnet (PM) brushless synchronous motor, also known as the brushless dc or ac servo motor. These motors have ...

Abstract: The DC-excited linear synchronous motor (DCELSM) is one of the major types of electrical machine used in high-speed maglev trains. But the longitudinal end effect is a flaw that may cause ...

Abstract: A new torque ripple reduction strategy is presented for permanent magnet synchronous motors in electric vehicle applications. Within the control scheme, the dc-link voltage of the traction ...

For motor applications, engineers have several options at their disposal. Typically, engineers can choose between direct-current (DC) or alternating-current (AC) motors. Machine Design has covered the ...

Selection of replacement motors is usually straightforward if the ratings are equivalent. Sometimes, however, a different type of motor is necessary or desirable. For success in these cases, it is ...

For power-efficient secondary-side synchronous rectification (SR) designs, Fairchild Semiconductor has introduced the FAN6204 controller which uses linear prediction timing-control. Not limited to the ...

Both at 100Hz and 1000Hz DC synchronization/control cycle frequencies, servo drives trigger warning errors. When using Intel NICs at 1000Hz DC synchronization/control frequency, all five servo motors ...
