The invention discloses a high-power-density motor, and belongs to the technical field of design and manufacturing of motors and new energy automobiles. The invention discloses a technical solution for greatly improving the electric power density without increasing the absolute rotating speed of a motor, and torque with opposite rotating speed and rotating directions output by double rotors can be reversed and converged into the same rotating speed and torque output through a power flow reversing and converging device, so that two or more times of torque output is obtained; the absolute rotating speed of the double rotors is not increased, so that the effect of greatly increasing the motor power on the premise of not increasing the absolute rotating speed of the motor rotors is realized. And harmony and unification of high power density, cost, safety and service life are obtained. The function of the motor can be a motor or a generator, the motor can be a high-power-density generator when being used as the generator, and two or more times of power generation capacity can be obtained within the equivalent volume and equivalent rotating speed range.

    一种高功率密度电机,本发明属于电机及新能源汽车设计及制造技术领域。本发明公开一种无需提高电机绝对转速让电动功率密度大幅度提升的技术解决方案,通过功率流换向汇流装置可以将双转子输出的转速旋向相反的扭矩换向汇流成同一转速及扭矩输出,从而获得2倍或多倍的扭矩输出,由于双转子的绝对转速并没有提高,所以实现了在不增加电机转子的绝对转速的前提下大幅度提升电机功率的效果。获得高功率密度、成本、安全性、寿命的和谐统一。该电机的功能可以是电动机或发电机,其功能用作发电机时将是高功率密度发电机,在等效体积及等效转速范围内将可以获得2倍或多倍的发电容量。
