The microcontrolled PLM Series of octal plug-in three-phase voltage monitors protects three-phase motors and other sensitive three-phase equipment from damaging or destructive voltage faults, the ...

NEC Electronics’ (distribution: Gleichmann Electronics) two new 3-phase control device families, V850E/IF3 and V850E/IG3, open up all kinds of new application possibilities. Key features of these ...

A motor control IC is a convenient way to implement custom motor drive algorithms such as the single-phase induction motor (SPIM) control. A generalized control algorithm, implemented and tested in an ...

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 ...

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 ...
