Motors differ from other types of loads in one important way: The motor needs much more current to start than to run. This temporary, but significant, inrush current is what complicates motor circuit ...

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 ...

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 ...

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 ...

Circuit protection has become a crucial design consideration to protect sensitive applications against overcurrent conditions. In most applications, overcurrent and overtemperature conditions are an ...

The Allen-Bradley Branch motor control components have been revised by Rockwell Automation. According to the company, this move was made to update systems where components are used to turn on and off ...

Read part 1 of this series on construction and operating principles here. Having understood the construction and basic operating principle of BLDC motor in the first part of this article, it becomes ...
