Where can I use a softstarter?
A softstarter can be used for any motor that requires a controlled and smooth start and stop. Emotron softstarters gives you a value added cost efficient means of controlling not only the startup and stopping phase but also observing the motor and machine load while running the motor. There are numerous applications, where the following are most common;
Softstarters for pumps
When using pumps in a process there is a risk of pressure surges. Using a soft starter and feeding the voltage to the motor in a gradual progression greatly reduces this risk to a pump application and water hammering in the surrounding piping. The internal load monitor will also detect e.g. cavitation or if a pump is running dry.
Softstarter for conveyor belts
A conventional Direct-On-Line start could put a lot of stress to the mechanical components of the conveyor belt. Conveyor belts are easily damaged if subject to a sudden start. A single jerk could result in a misaligned belt. By installing a soft starter, the conveyor belt will start up more smoothly by applying motor torque gradually. This can save many hours downtime. The Emotron Load monitor function will give possibility to catch e.g. a misaligned belt or other mechanical problems.
Softstarters for fans and blowers
Fans with belt drives also face a potential risk of slipping due to a jerky start. Using an Emotron softstarter eliminates this problem by applying a smooth torque controlled start. The internal load monitor in the Emotron softstarter will notice if a fan filter is starting to be blocked.
Softstarters for compressors
Softstarters are ideal for making a smooth start of compressors, using Emotron linear torque control at start to avoid mechanical shock for compressor, motor and transmissions. The built-in phase reversal alarm prevents starting compressor in wrong direction.
The internal load monitor in the Emotron softstarter will notice if a compressor is idling, allowing for energy savings by stopping.
Softstarters for crushers, mixers, mills, band saws
All applications where jamming might become an issue, such as a crusher or mill, will benefit from a softstarter. Applications with demands for extremely short braking times will benefit from the strong vector brake or reverse current braking for high inertia loads available in an Emotron softstarter.The built-in monitor will give a constant load indication.
