Star Delta Soft Starters

These soft starters utilize the star-delta process for motors with higher power ratings. They're primarily used in big applications because the star-delta arrangement reduces the motor power during starting, which then switches to delta for normal running. This results in significant savings in energy and reduction of the power.

Byphased Soft Starters

A byphase soft starter employs two of the three phases of power AC to start the motor. It resembles the star-delta soft starter in that it reduces the starting current, but the design is simpler, and the application is more common in smaller industrial motors.

Single-phase Soft Starters

For small motors that operate on single-phase electricity, a simple soft starter will do. These devices use control bouts to adjust the voltage output and bring about a gradual increase in current to the motor. It is common in small applications like residential HVAC systems or smaller industrial gear that runs on 1-phase power.

Controlled Soft Starters

Once in force, soft starters are controlled by methods that employ sensor feedback. These advanced starters maximize energy efficiency by modulating the starting torque and speed based on motor load conditions. This control type is gaining increasing acceptance in the field of sensitive and variable load applications.

Torque-Controlled Soft Starters

Devices starting with a system to control the starting torque are called torque-controlled soft starters. Soft starters are valued in industries where processes require constant torque, such as in conveyors or mixers. Controlling the torque prevents motor overloading, especially during situations of heavy load at start.

Autotransformer Soft Starters

As the name implies, soft starters operate with an autotransformer. The starter reduces the voltage sent to a motor during startup, lowering the starting current. Due to the higher equipment costs, these are mainly used in high power application centers, which require a substantial reduction in electrical currents when starting.
