Shakti Pumps (India) Limited, India's leading manufacturer of solar pumps and motors has received a patent for inventing "Methods & Apparatus for Soft Starting and stopping a Motor” The Patent Office, Government of India, has awarded Shakti Pumps this patent, fully adhering to the provisions set forth in the Patents Act of 1970. This patent is set to maintain its validity for duration of 20 years, commencing from the date of filing. This is the 13th Patent that the company has secured.

This patented technology offers numerous benefits for both motors and grid electrical systems. Firstly, it reduces mechanical stress on the motor and connected equipment by gradually ramping up motor speed, extending motor lifespan, and lowering maintenance costs. Secondly, it ensures a smooth and controlled start-up, preventing sudden torque and mechanical shock, which is particularly advantageous for delicate equipment and applications vulnerable to damage from abrupt starts. Additionally, soft starters limit inrush current during motor start-up, preventing voltage dips in the grid, thus avoiding penalties for exceeding power consumption limits and reducing the need for oversized electrical infrastructure.

Moreover, they provide precise control over acceleration and de-acceleration, enhancing system efficiency and reliability while minimizing equipment wear and tear, resulting in fewer breakdowns and extended equipment lifespan. Furthermore, the technology is compatible with generator-fed AC motors, reducing inrush current during start-up, improving generator lifespan, fuel economy, and reducing generator size requirements by 50 % compared to other starting methods.

Dinesh Patidar, Chairman of Shakti Pumps, credited the company's R&D team for achieving this milestone. He highlighted, "This patented technology marks a significant stride in our commitment to innovation and excellence in the electrical industry. Soft starters, a pivotal aspect of our patented technology, are set to transform global electrical systems by providing controlled motor starting and stopping while minimizing stress on equipment and the grid. This advancement not only enhances motor durability but also contributes to a more resilient and reliable electrical infrastructure."
