Abstract
Motors of modern design have less tolerance to overloads than their predecessors. In addition, present-day applications tend to utilize the maximum capability of motors. Induction -motor stator insulation or rotor bars may be severely damaged by over temperature due to repeated starts, locked rotors, cyclic loads and other conditions for which existing overload devices do not provide adequate protection.Keywords
