摘要： A method of extracting impedance parameters of a three-phase motor utilizes a five-terminal network including first to third winding wires and opposite shaft ends. The method includes connecting two terminals, selected from among the winding wires and the shaft ends, to input and output terminals in order to measure voltage and current of the terminals and to extract input impedance parameters of the five-terminal network, extracting conversion parameters including voltage and current transfer matrices in a common mode, in which the winding wires are commonly connected to the input and output terminals, and in a differential mode, in which the winding wires are differentially connected to the input and output terminals, and calculating impedance parameters in a mixed mode, in which transfer impedance components for the shaft ends in the common mode and the differential mode are mixed, using the extracted input impedance parameters and conversion parameters.

摘要： A motor winding pattern is provided. In a driving system in which a first inverter and a second inverter are connected to a drive motor, and one end of a stator winding through which a three phase currents flow is connected to an output line of the first inverter, and the other end of the stator winding is connected to an output line of the second inverter, coils to which three phase currents are applied are wound on slots defined in a stator of the drive motor, and coils to which alternating current phases different from each other are applied are wound inside and outside each of all the slots defined in the stator on the basis of direction toward a rotation axis of the drive motor.

摘要： In a driving system, first and second inverters are connected to a driving motor, one end of a stator winding through which 3-phase current flows is connected to an output line of the first inverter, and the other end of the stator winding is connected to an output line of the second inverter. A winding pattern of the driving motor includes: coils wound in slots defined in the stator and to which 3-phase current is applied; coils wound on innermost and outermost sides based on a direction toward a rotating shaft of the driving motor in the slots, and being energized by different AC phases; and coils disposed between a first coil located on the outermost side and a second coil located on the innermost side, and being energized by the same AC phases as those of the first and second coils.

摘要： A driving system of a driving motor is proposed. The system includes: a stator having slots at which coils are wound; a first inverter connected to first ends of the coils of the stator; a second inverter connected to second ends of the coils of the stator; and a stage switch circuit configured to control an electrical connection between the second ends of the coils of the stator and the second inverter. In particular, the coils include a first coil set connected to an output terminal of the first inverter, and a second coil set connected to an input terminal of the second inverter. Currents having the same phase or currents having different AC phases are applied to the first coil set and the second coil set wound at the slots by controlling on and off of the stage switch circuit.
