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 ...

Electric drives require effective protection against overloads and short circuits. Both phenomena cause motor disruption and create a risk of damage to the motor. This could lead to a potentially ...

Enhancing motor-drive apps with added safety, the ACPL-785J isolation amplifiers include both short-circuit and overload detection and allow direct measurement of motor phase currents in power ...

Circuit protection has proven useful, but meeting the increasingly sophisticated industrial and commercial requirements can be a challenge. An overload or short circuit in a fuse or mini circuit ...

In troubleshooting situations involving a motor, more than half the battle is simply isolating the problem. Whenever there’s a working motor, there’s a load and there’s some sort of motor controller, ...

Rockwell Automation’s Branch Motor Controls and Protection Solutions offer a range of combinations and accessories for applications that require smart industrial control. Electric motor starters ...

Safety is a major concern in a good many motor-driven applications. This is true in industrial applications where motion starts when power is applied and especially true when power is restored after ...
