Latest Patents

One of Dong Soo Shim's latest patents is titled "Brushless direct current electric motor driving control method and system of electrical water pump". This innovative method involves estimating the initial position of a rotor using the magnitude of current detected in a three-phase coil wound on a stator. It converts the current magnitude, which reflects the rotor's rotational angle, into two direct currents based on the three-phase current outputs. The system efficiently captures essential parameters such as the rotor’s rotational angle, speed, flux, and torque, allowing for precise motor speed adjustments.

Another notable patent is the "Method and system for controlling motor", which provides a limp home function when an error occurs in the Hall effect sensor that detects the rotor's position. This control method allows for continued operation of the automotive electric water pump even in the event of a sensor malfunction, by regulating the motor's speed based on counter electromotive force generated by multiple stator coils.
