Every industry and any application looks to install a motor that is both robust and high in efficiency. For this reason, most production lines are run by three-phase AC-type motors.
Protecting these motors while they are running with the help of specially developed equipment is essential for worry-free production.
Preventing the high inrush current while starting the motor helps release the stress on the electricity network. It ensures the safe run of the motor, which is vital for the smooth operation of any production line. A soft start that temporarily reduces the torque and load in the power while ensuring a smooth ramp-up of the motor prevents potential damage, thus maximizing the motor’s life span.
