Abstract: 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.

Abstract: 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.

Abstract: A stator for a motor that includes an armature coil that generates an N-pole and an S-pole by applying a current and forty-eight slots radially formed at which the coil is disposed and in which the armature coil alternately implements N-poles and S-poles by arranging six slots as a single unit as the current is applied to the coil. The slot includes a plurality of phase drawing out slots, and when the order of the phase drawing out slots is determined in a clockwise direction by setting one phase drawing out slot as a first phase drawing out slot, at least two methods of winding the armature coil to turn around the slot may be used to decrease a distance from the first phase drawing out slot to the last phase drawing out slot to a minimum value by setting a cell between neighboring slots as a unit.

Abstract: A motor control system is provided. The system includes an inverter that adjusts a stator current applied to a stator coil of a wound-rotor drive motor and a rotor current applied to a rotor coil of the drive motor. When an abnormal starting of the drive motor is detected and a movement of the vehicle is restricted by electronic parking brakes (EPB), a motor controller adjusts the rotor current through the inverter to cancel an abnormal starting torque caused by the abnormal starting.
