The invention relates to the technical field of motor controllers, in particular to a single-tube power module assembly, a motor controller applying the single-tube power module assembly and a pure electric vehicle. The single-tube power module assembly comprises a driving plate, a shielding cover assembly, a negative switching copper bar assembly, a metallized film capacitor, a three-phase copper bar assembly, a single tube assembly, an insulating plastic piece and a PINFIN heat dissipation plate, wherein the driving plate is fixedly installed on the shielding cover assembly, and is welded to the signal pin PIN of the single tube assembly, the single tube assembly is fixedly connected to the PINFIN heat dissipation plate provided with the insulating plastic piece, the metallized film capacitor is connected with the single tube assembly and the negative switching copper bar assembly, and the single tube assembly is further connected with the three-phase copper bar assembly. According to the single tube power module assembly, the problems of complex process and low reject ratio caused by a single-tube bending process are solved, so that the whole machine structure is relatively simple and compact, the installation is easy, the process cost is saved, and the whole machine scheme is convenient for modular design.
