Latest Patents
One of Jianchun Qin's latest patents is titled "Induction motor slip calculation." This intelligent electronic device (IED) can estimate a full load rotor resistance value as a function of motor positive-sequence resistance. The IED achieves this by measuring zero-crossings of voltage after a motor disconnect. Additionally, it acquires motor current and voltage measurements to calculate motor slip using the estimated full load rotor resistance value.
Another significant patent is "Electric motor thermal protection using stator current measurements." This innovation involves monitoring the thermal conditions of an electric motor using current signals from the power supplied to the motor. The current signals are utilized to calculate composite current values, which can then be used to determine slip. This slip calculation provides thermal monitoring and protection for electric motors, especially in cases where rotor measurements are not available.
