The invention discloses a special electric power steering controller for a limited mounting space. The special electric power steering controller comprises a PCB (Printed Circuit Board), a base and a cover plate, wherein a conical supporting column and a heat conducting seat are integrally molded above the base; the PCB is placed on the conical supporting column, located through two locating columns which runs through the PCB and fixed on the heat conducting seat through a bolt; the cross sections of the two locating columns are different; the base and the cover plate are pressed together; the conical supporting column is positioned in the cover plate; the cover plate and the base are buckled in an increasingly tighter way; a triangular mounting error preventing mark is arranged at the top of the cover plate close to the right rear corner; four upwardly extending cylinders distributed in the form of a rectangle are integrally molded on the base; and thread mounting blind holes with the number equal to that of the cylinders and corresponding to the cylinders in position are formed in the back face of the base. The special electric power steering controller for the limited mounting space, disclosed by the invention, is advantaged in that problems that slight shaking exists between the base and the cover plate and between the PCB and the base after the base, the cover plate and the PCB are mounted, the local temperature of the PCB is too high and the cover plate and the PCB are reversed are effectively solved; and the special electric power steering controller exerts a dustproof effect.
