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.

Vehicle and method of controlling the same

An apparatus for controlling a drive motor of a vehicle in which a wound rotor synchronous motor is mounted includes: an inverter which controls a stator current supplied to a stator of the drive motor and a rotor current supplied to a rotor of the drive motor; and a drive motor controller which controls the inverter such that the stator current and the rotor current are supplied to the drive motor when a temperature of the rotor is less than a threshold value, and only the stator current is supplied to the drive motor when the temperature of the rotor is greater than or equal to the threshold value.

Apparatus for controlling drive motor of vehicle and method using the same

A drive motor for a vehicle includes: a stator and a rotor, in which the stator includes: stator teeth which are disposed between multiple slots, respectively, the multiple slots being formed at predetermined intervals in a circumferential direction corresponding to an outer circumferential surface of the rotor, and have a blocking portion which protrudes toward one of the slots disposed at both sides, the blocking portion formed at one side of an inner circumferential surface of each of the stator teeth facing the rotor, and a groove which is formed radially outward at an opposite side of the inner circumferential surface of each of the stator teeth; and opening sections each of which is in communication with the slot and formed between the blocking portion and the opposite side of the inner circumferential surface of the stator tooth adjacent to the blocking portion, and the slot is opened radially through the opening section.

Drive motor for vehicle

A vehicle includes: a motor including a stator and a rotor; an inverter configured to drive the motor; a battery, which is rechargeable; and a controller configured to change a position of the rotor based on whether the position of the rotor is identical to a predetermined position. Additionally, the controller is configured to control the inverter such that the battery is charged after the position of the rotor changes.

Vehicle and a control method thereof

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.
