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), ...

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 ...

A good indication that a motor may be overloaded is overheating, or in some cases not starting at all. For HVAC motors it can be as simple as belts that may be too tight, inadequate wiring, or voltage ...

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 ...

Jams or sudden stops during an indexer's moving periods can subject its drivetrain to damaging torques. A few setups prevent damage in such situations. In engineering, indexing is the movement from an ...

Article 430 contains the specific rules for conductor sizing, overcurrent protection, control circuit conductors, controllers,, and disconnects for electric motors. The installation requirements for ...

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 ...
