A Discrete Algorithm for Overload Protection Principle

Article Preview

Abstract:

Research thermal overload protection not only to protect the motor winding insulation damage due to temperature is too high, also can give full play to the overload capacity of the motor. This paper proposed overload protection model based on heat effects, and deduces the motor internal discrete recursive algorithm of temperature-rise calculation. Based on this algorithm, we constructed the motor internal temperature-rise model, which can calculate temperature-rise of the motor in real-time, and realized the intelligent control of the motor.
