Summary: | A method is provided for controlling of an AC induction motor by starters realizing transient conditions of desired quality nevertheless changing conditions of a power supply and a motor charge. The method for controlling a starting and stopping is based on step-by-step changing of a power consumption of the motor in a moment, defined on every step. When transient conditions of now in use step reach near equilibrium conditions or impermissible transient conditions, it is the moment for changing characteristics of current supplied to the motor. The method for controlling the starting and the stopping is used for controlling a rotation speed of the motor. A regulator, which produces its control signal with accordance to an algorithm control of the rotation speed, defines direction of changing motor power consumption. Addition conditions prevent negative interaction of the speed control and the starting or stopping control. |
