The invention discloses a special high/low-speed multi-motor clutch type combined brushless DC (direct current) motor for a passenger car. The motor comprises more than two rotation shafts; the rotation shafts are sequentially and coaxially connected through a one-way clutch; each rotation shaft is provided with a rotor; a stator is mounted in a base corresponding to each rotor so as to form more than two independent sub-motors; mutual interference among the electric circuits and magnetic circuits of the sub-motors is avoided; the sub-motor beside an end cover of a non-shaft extension end is an auxiliary torque increasing motor with low rotation speed and high torque, and the other sub-motors are main motors with high rotation speed and low torque; the winding circuit and the Hall sensor circuit of each sub-motor are independent and are respectively connected to respective controllers; and an external DC power supply is connected with each controller through a group of power switches, and controls the power o
