A Comprehensive Guide to Soft Starters in China

China has emerged as a significant player in the global soft starter market, boasting numerous manufacturers producing a wide range of products for diverse industrial applications. Companies like DELIXI (www.delixielc.com), MICNO (www.micnodrive.com), NOKER (www.noker-inverter.com), VEIKONG (veikong-electric.com), and AUBO (www.vfd-softstarter.com) are prominent examples of this robust industry. This guide delves into the intricacies of soft starters, their technical specifications, and the variations available in the Chinese market.

Soft starters are advanced motor control devices designed to regulate the starting and stopping of electric motors. Unlike direct-on-line starting, which subjects motors to high inrush currents and mechanical stress, soft starters gradually increase the voltage applied to the motor. This controlled acceleration minimizes the strain on both the motor and the power supply, extending the lifespan of equipment and improving overall efficiency. They also offer smooth stopping, preventing the sudden torque shocks that can damage machinery.
