Automatic regulation method and system of elevator starting torque [Invention]

The invention discloses an automatic regulation method and system for elevator starting torque. By introducing a position loop operation control module into the original frequency converter vector control system, the position loop PI operation control is processed to compensate the given frequency, thereby effectively carrying out vector control of the motor and avoiding rollover. Obtain the comfort of the elevator at start-up without weighing device.

Method of Controlling Motor with Frequency Converter and Frequency Converter [Invention]

The patent uses a three-phase lower bridge arm sampling resistor for current sampling. Accurate current sampling and accurate measurement of asynchronous motor parameters in the circuit topology are achieved by specific algorithms.
