Why GRR starts from 60% of motor speed why not less than 60%?



Why GRR starts from 60% of motor speed why not less than 60%?..

Answer / Radhe Shyam Rai

Starting GRR (Gear Ratio Reduction) at 60% of the motor speed is a common practice due to various reasons, including minimizing starting torque, reducing wear and tear on the gears, and ensuring smooth operation. Starting GRR below 60% could lead to increased power consumption and potential mechanical issues.
