Adjusting the motor torque is best done by controlling the current in all three phases. 3-phase control offers symmetrical and balanced currents without the drawbacks of additional energy losses, noise and vibration normally connected with 2-phase soft starters.

Emotron TSA Soft Starts incorporate 3-phase control together with sophisticated algorithms for torque control. Conventional Soft Starts use a pre-defined voltage ramp to control the start. With Emotron TSA, the actual motor torque is continuously calculated and controlled according to the application requirements. This torque control ensures an ultra-smooth start with constant acceleration. The torque control means the starting current is reduced even further by up to 20%. You can use smaller fuses and less expensive cables, and will thus benefit from lower installation and energy costs. The smooth starts also lead to less mechanical stress, improved process control and reduced maintenance costs.
