Abstract
A high-efficient asynchronous motor for a new-energy automobile comprises a 36-groove four-pole stator and a 44-groove rotor, and casted aluminum rotor grooves are inclined. The high-efficient asynchronous motor is further provided with air vents, balance columns and fan blades, wherein the grooves of the rotor is flat-bottomed grooves with inclined shoulders, the grooves of the stators are pyriform, and the casted aluminum rotor is made of special materials. The gullet torque is eliminated, so that the operation of the motor is more stable, and the torque ripple is smaller. The motor employs a rotor inclined groove structure, which reduces the noises during operation of the motor. The air vents substantially accelerates heat radiation of the motor, thereby prolonging the service life of the motor, reducing the inertia moment of the motor, and making the respond speed of acceleration and deceleration of the motor faster. The balance columns adjust the dynamic balance of the motor, and improve efficiency. The fan blades accelerate internal circulated heat radiation during the operation of the motor. The stator and rotor groove cooperation of the motor is reselected, and the groove types of the stator and the rotor groove of the motor are redesigned, so that the efficiency and power factor of the motor are improved. The casted aluminum of the rotor employs a unique formula, so that the resistance of the end rings and conducting bars of the rotor is lower, and the copper consumption of the motor is reduced.
