1. A motor-driven power board, which is characterized in that it further includes:
a PCB (printed circuit board) (10);
a plurality of transistors (2) uniformly arranged along an edge of the PCB (10);
a plurality of capacitors (6) disposed on the PCB (10) and are uniformly arranged along a side of the plurality of transistors (2) near a center of the PCB (10);
a plurality of terminal posts (8) disposed on the PCB (10) and are uniformly arranged along the side of the plurality of transistors (2) near the center of the PCB (10), and are arranged between two adjacent capacitors (6) of said plurality of capacitors;
a positive pole (3) of power bus disposed on the PCB;
a negative pole (4) of power bus disposed on the PCB; and
a signal wire (5) disposed on the PCB (10);
wherein the plurality of transistors (2) are vertically disposed on a plane of the PCB (10), and wherein a heat dissipation surface of each of the plurality of transistors (2) is perpendicular to the plane of the PCB (10), and wherein the heat dissipation surface of each of the plurality of transistors (2) faces a periphery of the PCB (10).
