The application of flat enameled wire in new energy vehicle motors
Compared with ordinary round enameled wire windings, flat enameled wire windings have the characteristics of higher energy density, higher motor efficiency, corona resistance, high insulation strength, zero pinholes, and smooth surface under the same volume, which can replace ordinary round enameled wires. Used in new energy vehicle motors.
The main application of flat enameled wire in new energy vehicle motors:
As the heart of a new energy vehicle, there are many electromagnetic wires in the drive motor. If the magnet wire and insulating material cannot withstand the high voltage, high temperature, and high voltage change rate during the operation of the motor, they will be easily broken down and reduce the service life of the motor. At present, when most companies produce enameled wires for drive motors of new energy vehicles, due to the simple process and single paint film, the products produced have poor corona resistance and poor thermal shock resistance, which affects the service life of the drive motor.
Using flat enameled wire instead of enameled round wire, theoretically speaking, under the premise of the same space, the filled copper can increase by 20-30%, and the flat enameled wire winding stator can increase the slot full rate by 20%. The improvement of this index means In the case of the entire motor space unchanged, the maximum current that the motor windings can pass can be increased by about 15%, which is equivalent to an increase of 15% in the maximum torque and motor power. Conversely, when the power is the same, the outer diameter and volume of the motor can be reduced, thereby reducing the amount of other materials used in the motor.
