Soft Starter
The high inrush current and mechanical jerks are the two main problems associated with the Induction Motor since the invention. The different reduced voltage starting methods like start/delta, Auto transformer and switched rotor resistance were used but never solved the issues satisfactorily.
Soft starter is a device which is used to smoothly start the 3-phase squirrel care induction motor. It provides a gentle ramp-up to full speed. Ramping up the initial voltage to the motor produces this gradual and smooth start, increasing the life of components and reducing the harmonic effect in the plant.
For the last more than three decades, Amtech is providing the solid state soft starters, the answer to the inrush currents and associated mechanical jerks.
Amtech's soft starter increases motor's lifetime by protecting it from electrical stresses by optimizing the starting currents. Your motor is safe thanks to the in-built protective functions which ensure complete motor protection.

Frequently Asked Questions
A soft starter is an electrical device used to control the initial voltage supplied to an electric motor, ensuring a smooth and gradual start. This minimizes mechanical stress, reduces energy consumption, and enhances equipment lifespan. Amtech, a trusted brand, offers reliable soft starters designed for industrial applications, ensuring efficient motor operation and reduced downtime.
To select an Amtech soft starter, consider these factors: motor power and voltage rating, application type (pumps, compressors, conveyors, etc.), required starting torque, overload protection, and integration needs (communication protocols). Ensure compatibility with existing electrical systems and verify the environmental conditions (temperature, humidity). Consult Amtech's product guide or technical support for precise recommendations.
Soft starters are devices used to control the starting current of electric motors, reducing mechanical stress and electrical surges. The two main types are: 1. Electromechanical Soft Starters and 2. Solid-State Soft Starters.
A soft start by Amteche is used to reduce electrical and mechanical stress during the startup of motors. It gradually increases voltage, minimizing inrush current, preventing sudden torque, and ensuring smoother operations. This prolongs equipment life, enhances energy efficiency, and reduces downtime, making it ideal for applications in industrial systems, pumps, conveyors, and fans.
Yes, a soft starter saves energy indirectly by reducing inrush currents and mechanical stress during motor startups, prolonging equipment life and lowering maintenance costs. It minimizes power wastage during the startup phase.
