Background

The development trend of high-performance electric vehicles is to have short acceleration times of 0-100 km, but long cruising distances. The components of modern electric vehicles include electrical drive and control systems, mechanical systems such as drive transmission, and working devices for performing established tasks. The electric driving and controlling system is the core of the electric automobile and consists of a driving motor, a power supply, a speed regulating control device of the motor and the like. The performance of the drive motor substantially determines the performance of the electric vehicle. The types of common driving motors of the new energy automobile at present are a permanent magnet synchronous motor and an asynchronous motor. Compared with the permanent magnet synchronous motor, the asynchronous motor has the same technical requirements, and the highest efficiency point of the asynchronous motor is probably comparable to that of the permanent magnet synchronous motor. New energy automobile tesla adopts three-phase induction motor, three-phase AC asynchronous motor promptly, can pass through super high voltage and weak magnetism drive, realizes the high rotational speed that exceeds 10000 commentaries on classics, simultaneously through electric control system such as drive converter, can realize the motor and move at 600 Nm's big moment of torsion, guarantees tesla motor output high power from this to promote tesla power performance, asynchronous motor accomplishes steadily driving easily, can the high speed of efficient drive, this is relative permanent magnet synchronous motor's obvious advantage. The permanent magnet synchronous motor can be used as a generator and a motor, is a synchronous motor which generates a synchronous rotating magnetic field by permanent magnet excitation, the permanent magnet is used as a rotor to generate a rotating magnetic field, a three-phase stator winding is reacted through an armature under the action of the rotating magnetic field to induce three-phase symmetrical current, at the moment, the kinetic energy of the rotor is converted into electric energy, and the permanent magnet synchronous motor is used as a generator; in addition, when three-phase symmetrical current is introduced to the stator side, the three-phase stator current generates a rotating magnetic field in the space due to the fact that the three-phase stator differs by 120 degrees in spatial position, the rotor rotates under the action of electromagnetic force to move, electric energy is converted into kinetic energy at the moment, and the permanent magnet synchronous motor serves as a motor. Because modern high-performance electric vehicles need to have super-strong driving force and increase the endurance distance, especially high-tech new energy batteries are developed quickly, the battery size is reduced, the charging time is shortened to less than 15 minutes, and the single-charging driving mileage is doubled. The single technical performance of the two motors cannot meet the requirement of improving the performance of the modern new energy electric automobile.
