From tiny hysteresis motors that drive electric clocks to huge synchronous motors that develop more than 50,000 hp, the alternating current (AC) motor has become an indispensable part of everyday life ...

Electric motors are said to consume nearly 50% of the world's electricity. Industry is focused on replacing inefficient constant-speed drives and motors with microprocessor-driven variable-speed units ...

Sometimes you may need to correct power factor (PF) at a single motor. This means sizing PF capacitors for that motor. The good news: If you size these capacitors correctly, you'll lower your ...

The thyristor d.c. drive remains an important speed-controlled industrial drive, especially where the higher maintenance cost associated with the d.c. motor brushes (c.f. induction motor) is tolerable ...
