摘要： A temperature calculation system for a motor uses a thermal equivalent circuit wherein a yoke is disposed to be fixed onto an inner circumferential surface of a housing of the motor, a coolant chamber in which a coolant flows is formed in a circumferential direction in the housing, and the thermal equivalent circuit including thermal resistance coefficients and temperatures is used. An endothermic amount of the coolant flowing in the coolant chamber of the housing is calculated by using an average temperature of the housing and a preset equation.

摘要： A bearing for a drive motor is provided. The bearing includes an inner race that is coupled to a rotation shaft, an outer race that is coupled to a motor housing, and rolling members that are rotatably disposed between a raceway surface of the inner race and a raceway surface of the outer race. Additionally, a retainer is disposed between the inner race and the outer race and supports the rolling members at a predetermined interval along a circumferential direction. A conductive guide member is formed in each of the inner race and the outer race and forms a current path between the inner race and the outer race through the retainer.

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 temperature calculation system includes a yoke disposed along an inner circumference, first and second teeth arranged on an inner circumference surface of the yoke while having an interval set in a circumference direction, and a coil member formed between the first and second teeth and including a plurality of coils, forms a thermal equivalent circuit of the coil member, and calculates a temperature of a set portion of the coil member. An outer circumference surface temperature and an inner circumference surface temperature of the coil member are calculated by using radial conduction resistance using a temperature of an inner one side of the coil member. An average temperature of the coil member is calculated by using compensation resistance from the temperature of the inner one side of the coil member, thermal capacity of the coil member, and a heating amount of the coils formed in the coil member.
