Title: ELECTRONIC GOVERNOR AND MOVABLE PLATFORM
Abstract:
An electronic governor (100), comprising: a shell and a circuit board (130) arranged in the shell. The circuit board (130) comprises an upper surface (130a) and a lower surface (130b) arranged on the back of the upper surface (130a) and facing the opposite direction; the upper surface (130a) is arranged facing one inner wall of the shell, and the lower surface (130b) is arranged facing the other opposite inner wall of the shell; the upper surface (130a) is provided with a plurality of first metal oxide semiconductor (MOS) transistors (150a), and the lower surface (130b) is provided with a plurality of second MOS transistors (150b); top surfaces of the first MOS transistors (150a) and the second MOS transistors (150b) are all embedded with heat-conduction metal plates (150c); the heat-conduction metal plates (150c) of the first MOS transistors (150a) are connected to one inner wall of the shell in a heat-conduction manner by means of a first heat-conduction pad (160a); and the heat-conduction metal plates (150c) of the second MOS transistors (150b) are connected to the other opposite inner wall of the shell in a heat-conduction manner by means of a second heat-conduction pad (160b). The heat radiation property of the electronic governor is good, and a miniaturized design of the electronic governor is facilitated. Also provided is a movable platform which is applied to the electronic governor.
