Generally speaking, three-phase motors are less troublesome than single-phase motors, having no starting relays or capacitors to deal with. All three-phase units are high-starting-torque motors and ...

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 ...

The CSD oil switches from Trinetics are single-phase, motor-operated capacitor switches designed for 15kV and 25kV, and also for 35kV grounded wye distribution applications. The CSD oil switches from ...

Single-phase ac motors are as ubiquitous as they are useful -- serving as prime power sources for a seemingly limitless array of small-horsepower applications in industry and home.

A squirrel cage induction motor must sense two or more electric phases to cause the magnetic field to start spinning, thus turning the motor’s rotor and shaft. Once the motor starts, the interaction ...

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 ...

Researchers have designed a new switched-capacitor-based multilevel inverter topology with nine switches. They have tested it in simulations and in hardware-in-the-loop tests. Efficiency reached up to ...

A study led by Dr. Haitham Kanakri and Dr. Euzeli Dos Santos, Jr., has unveiled a novel capacitorless solid-state power filter (SSPF) for single-phase DC-AC converters. This innovative technology ...
