Description:

• A soft starter is a device that starts motors with less power at startup.
• Soft Starters adjust the amount of current delivered to the motor, allowing the AC induction motor to accelerate in smaller steps, requiring less current than a typical motor starting.
• Because of the lower voltage, torque is also reduced, resulting in a soft/easy start.
• During the start-up phase, a Soft Starter constantly regulates the voltage supply to a three-phase motor.
• This decreases mechanical stress on the motor and shaft, as well as electrodynamic stress on the attached power cables and electrical distribution network, hence increasing the system's lifespan.
