DEFINATIONS

The terms frequently used in the intermittent duty drives are as follows:

  • DUTY : operation of the motor at load & energized period to which the motor is subjected including the sequence & duration.
  • PROTECTION : Cyclic Duration on Factor (CDF): The ratio between the period of loading including starting & electric breaking and the duration of the duty cycle expressed as percentage.
  • CYCLIC DURATION ON FACTOR (CDF) : The ratio between the period of loading including starting & electric breaking and the duration of the duty cycle expressed as percentage.
  • STARTING : The process of energizing a motor to bring it up to its rated speed from rest.
  • ELECTRIC BREAKING : A system in which a braking action is applied to an electric motor by causing it to act as a generator.
  • REGENERATIVE BRAKING : A system of electric braking in which energy is returned, to the supply system.
  • PLUGGING : A form of braking of an induction motor obtained by reversing the phase sequence of its any two lines.
