Long before Jayashree Group became a global leader, its foundation was laid by the vision and determination of Late Mr. Ram Bapat. A motor designer by profession, worked with many MNC in his early years. Mr. Bapat contributed to some of the most advanced designs and projects of his time. Driven by patriotism and a belief that India must develop its own technological capabilities, he chose to build indigenous solutions instead of relying on imports.
In 1972, he founded Jayashree Group along with his wife, Mrs. Jayashree Bapat, a science graduate who played a key role in the company’s early development and is always active and participating even today. The company’s first innovation was the patented “Remon” electrodynamic speed monitoring instrument...
Jayashree’s Pure Electrical Dynamic L-C technology is the industry benchmark for motor soft starting. By intelligently tailoring dynamic series impedance and mutual inductance of the HFSR™ modules and impedance ratio of motor to HFSR; resulting in voltage ramp up .

A Variable Rotor Impedance (VRI) Rotor Controller enables smooth motor acceleration by inserting controlled resistance into the rotor circuit. It delivers adjustable starting torque and limits inrush current to nearly 1× FLC. By dynamically varying rotor impedance, it ensures gentle starts, reduced mechanical stress, and reliable performance for heavy‑duty slip ring motor applications.
