A typical low-voltage variable-frequency drive. Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a ...

If a motor isn't adequately protected, a short circuit will likely result in premature replacement. Then there's the problem of nuisance tripping upon initial start-up because the magnetic setting of ...

Have you ever wondered why a car’s city fuel economy is always lower than its highway fuel economy? Most cars spend a lot of time stopping or traveling at low speeds, especially in a city. Start-stop ...

The usual way of preventing a small motor from drawing too much current is to install overcurrent protection in the form of a circuit breaker or some other kind of limiter. But installations that ...

Often, many different types of protection of the power transistor, motor or any part of the system are required in motor drive applications. Current protection of the inverter is one of the crucial ...

An overload or short circuit in a fuse or mini circuit breaker can lead to undersupply or failure of an entire 24-V dc power-supply system. Selectivity protection using an electronic fuse offers a ...

Now that autos are moving toward high-powered battery voltage, the industry is turning new attention toward making sure the flow can stop on a dime when needed. Power management company Eaton Corp.
