The flux-oriented control (FOC) is a commonly used technique for three-phase electric motor control application. Here, the applied voltage pattern is defined using the space vector modulation (SVM) ...

It’s impossible to balance line-to-line voltages perfectly in three-phase circuits, so they typically differ by a few volts or more. However, if voltage unbalance exceeds 1%, it can markedly decrease ...

Q: Would you happen to know the answer to this non-wood question? Given a choice of a single phase motor or 3-phase motor, which is best? A: The Wood Doctor does indeed know the answer. No question ...

There are several reasons to use a three-phase inverter to run a single-phase induction motor, including isolation from variable power grids, reduction of peak currents and elimination of the starting ...

Every day engineers design products that employ single-phase induction motors. Speed control of single-phase induction motors is desirable in most motor control applications since it not only provides ...

One of the more popular three-phase electrical services supplied to medium-size commercial buildings is the Wye or Star configuration transformer. The name comes from the transformer’s secondary ...

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 the original version of this article, the second figure contained an error. The image has been updated. It’s important for engineers to have a good, working ...

Oriental Motor USA is proud to introduce our new three-phase standard AC motor, the KIIS Series Standard AC Motor, available in 60 W (1/12 HP) and 100 W (1/8 HP) output power. Oriental Motor USA is ...
