The invention discloses a four-channel steering engine controller resistant to overload and large temperature
impact. The controller includes a controller shel, and an assembled circuit
assembly is arranged in the controller shell; an insulating damping layer is arranged at the bottom of the assembled circuit
assembly, a throwing cable electrically connected with the outside is arranged on the assembled circuit
assembly, the assembled circuit assembly is fixed in the controller shell through a standard part and is encapsulated through pouring
sealant, and the controller shell forms a
solid body through the assembled circuit assembly and the pouring
sealant. According to the four-channel integrated steering engine controller, a
digital control circuit and a power
driving circuit are integrated, in a limited structural space, the four-channel integrated steering engine controller is electrically connected with the outside in a line throwing mode through circuit integration and
potting reinforcement, the ultrahigh overload capacity is achieved, the overload magnitude reaches 23000g, and meanwhile the use requirement of the high-temperature-
impact-resistant environment is met. The problem that an electric
servo mechanism is small in structural space and high in environment resistance is solved, and the ultrahigh overload steering engine controller is achieved.
