UNIT – I

Jun 17, 2002 · If voltage dip is too large, the motor will over heat or not start because there is not enough torque to accelerate the motor. Motor torque falls off approximately as the product of reduced squared. For example, with a 30% voltage dip resultant torque, it will be: T= (.70 volts) 2 = .49 or 49% available torque. ................
