The application relates to the technical field of power equipment, in particular to a dual-control motor power assembly and an electric automobile. The dual-control motor power assembly comprises a gear box, a first motor, and a second motor. The first motor is arranged on one side of the gear box, and an output shaft of the first motor is connected with an input shaft on one side of the gear box;the second motor is arranged on the other side of the gear box, and an output shaft of the second motor is connected with an input shaft on the other side of the gear box; and the phase angle of thefirst motor and the phase angle of the second motor are 180 degrees. According to the dual-control motor power assembly, the first motor and the second motor are arranged on the two sides of the gearbox, and the phase angle of the first motor and the phase angle of the second motor are 180 degrees, so that sound waves generated by the first motor and the second motor are mutually counteracted, and thus the noise of the dual-control motor power assembly is reduced.
本申请涉及动力设备技术领域,特别涉及一种双控制电机动力总成及电动汽车。双控制电机动力总成,包括:齿轮箱;第一电机,所述第一电机设置于所述齿轮箱的一侧,所述第一电机的输出轴与所述齿轮箱一侧的输入轴连接;第二电机,所述第二电机设置于所述齿轮箱的另一侧,所述第二电机的输出轴与所述齿轮箱另一侧的输入轴连接;其中,所述第一电机和所述第二电机的相位角为180°。本申请中的双控制电机动力总成,第一电机和第二电机设置于齿轮箱的两侧,且第一电机和第二电机的相位角为180°,以使第一电机和第二电机产生的声波相互抵消,从而降低双控制电机动力总成的噪声。
