Abstract: A vehicle and method of controlling the same are provided in which the performance of an electric motor is prevented from being degraded by efficiently and more accurately calculating the temperature of a permanent magnet within the electric motor to adjust the amount of power supplied to the electric motor. The vehicle includes an electric motor having a stator, a rotor, and a permanent magnet and a sensor that measures the temperature of the electric motor. An inverter drives the electric motor and a controller generates a predetermined heat quantity by supplying power to the electric motor to calculate the temperature of the permanent magnet based on the temperature of the electric motor at a predetermined point measured using the sensor. When the temperature of the permanent magnet exceeds a predetermined temperature, the controller reduces the supply of the power.

Abstract: A structure for measuring iron loss of a motor stator core is provided. The structure includes an auxiliary core whose both end surfaces in a longitudinal direction come in contact with inner end surfaces of two adjacent stator teeth among a plurality of stator teeth in a radial direction in order to measure iron loss of a stator core in which a plurality of slots and the plurality of stator teeth are alternately formed on an inner circumferential surface of a stator yoke in a circumferential direction. A pair of excitation windings is provided at portions of the auxiliary core in the longitudinal direction spaced-apart from each other. A B-coil that is a sensor coil is provided at the auxiliary core so as to be positioned inside any one excitation winding of the pair of excitation windings. Fixing protrusions protrude from the both end surfaces of the auxiliary core to extend in the longitudinal direction, and inserted into the slot between the two adjacent stator teeth to be fitted and fixed in the circumferential direction. Accordingly, it is possible to quantitatively and accurately measure iron loss of the motor stator core for each manufacturing process.

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.
