The Baldor MST series three phase soft-starter is the most advanced Baldor soft start product offered. Three phase induction motor starting is a very dynamic process. Starting the motor and accelerating the load to full speed exposes electrical and mechanical equipment to stresses and fatigue. Starting and acceleration are affected by several factors. Dynamic forces and jerk that cause mechanical equipment fatigue and wear are often caused by this accelerating torque dynamic profile.
Starting stresses are often reduced by implementation of various reduced voltage starting methods of which the three phase six SCR (silicone controller rectifier, thyristor) solid state starter is the only starter that offers smooth ramp from initial starting to full voltage over the acceleration time.
Baldor MST series soft starter features advanced torque control algorithm with proprietary SCR control technique that adapts starting voltage and starting current to provide smooth and steady accelerating torque.
