Thanks to ongoing innovations in technology, electrical engineers' approach to motor protection has changed over the years. The traditional strategy to large AC motor protection (e.g., over 500 hp), ...

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 ...

Bob is a service technician who is well trained and nationally certified. However, he sometimes suffers from the same confusion that all technicians occasionally do - the facts that he gathers may or ...

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 ...

AutomationDirect announces the release of a new White Paper, “Group Motor Protection”, that explains how the usual way of preventing a small motor from drawing too much current is to install ...

The RSGD Series from Carlo Gavazzi is an easy to use soft-starter for 3-phase induction AC motors, needing just three settings. The self-learning algorithm adjusts the unit's parameters to work with ...

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 ...

Sensorless stall detection without the need for an encoder is incorporated in the TMC246 and TMC249 driver chips. Both devices can predict a motor overload, which is important in high-reliability ...
