Where three-phase power is unavailable or impractical, it’s single-phase motors to the rescue. Though they lack the higher efficiencies of their three-phase siblings, single-phase motors — correctly ...

THE first edition of this work appeared in 1904. Since then remarkable advances have been made in electrical engineering. A foremost place in this progress must be given to electric motors, and more ...

Electric fans commonly use low-cost AC motors built around capacitors, which now increasingly demand replacement due to high power consumption. However, while three-phase brushless DC (BLDC) motors ...

In this single phase induction motor, energy from the primary winding in yellow is coupled through a magnetic core to a rotary structure called a bobbin, which acts as a short circuited transformer ...

RECENT advances in the application of single-phase alternating currents to electric traction have given rise to a large volume of literature dealing chiefly with the motors employed. The possibility ...

Single-phase motors are common in many industries and can be found in blowers, pumps, fans, lathes, and numerous other types of equipment. Single-phase motor failures or malfunctions can often be ...

Home machinists can often find great deals on used industrial equipment, and many a South Bend lathe or Bridgeport milling machine has followed someone home. Then comes the moment to plug it in, and ...

If you made a motor out of a magnet, a wire coil, and some needles, you probably remember that motors and generators depend on a rotating magnetic field. Once you know how it works, the concept is ...

Single-phase motors, adjustable-speed drives (ASDs), and power factor (PF) correction applications often depend on capacitors to operate properly. This article explains how to test these critical ...

Note: This specialization requires purchase of a hardware kit in order to apply your knowledge and skill with real world tools. The hardware will be used to complete the lab exercises across the four ...

Aerotech’s XL4s linear amplifier for closed-loop servo control of voice coil and single-phase motors eliminates the nonlinearities common with PWM amplifiers. The unit provides deterministic behavior, ...
