The invention discloses an integrated sewing machine electric control device, belonging to the technical field of sewing machine electric control devices. By adopting the device, the problem that the heat dissipation effect of existing sewing machine electric control devices is not good enough is solved. The integrated sewing machine electric control device comprises a shell and a mounting frame positioned in the shell, wherein an operation panel is arranged on the outer side of the shell. The electric control device also comprises a circuit board, wherein the circuit board is positioned on the inner side of the mounting frame and between the mounting frame and the shell; multiple power devices are arranged on the circuit board and are vertical to the mounting frame; a mounting part is arranged on the edge of one end of the mounting frame; a concave part is arranged on one side of the mounting part close to the circuit board; the power devices are fixed in the concave part; and a convex part corresponding to the concave part is arranged on one side of the mounting part away from the circuit board. In the electric control device, the mounting part is arranged on the mounting frame; and through the structural design of the mounting frame and the shell, the heat dissipation effect of the power devices is relatively good.
