Soft start motor starters are used during the start up process of an electric motor by temporarily reducing the initial torque and load. Soft starters reduce the mechanical stress on the motor and shaft and the electrodynamic stress experienced by power cables and the electrical network, continuously monitoring the initial load and electrical current surges typical with motors during their start-up phase. Soft starters are only utilised during the start-up phase of an electric motor.
Within industrial applications soft start motor starters help to avoid pressure surges that could occur in motor driven pumped systems, smoothing the operation of conveyor systems by avoiding sudden jerking and the associated stress on mechanical components. System which feature belt drives will benefit from being able to be started slowly, reducing the potential of slipping belts and the increased wear of components. Whatever motor driven systems a soft starter is incorporated it will limit the inrush current to a motor, improving the stability of the power supply and reducing transient voltage drops that may affect over loads.
