Active ventilation cooling device of switched reluctance motor controller

The invention relates to the field of motor heat dissipation, in particular to an active ventilation cooling device of a switched reluctance motor controller. According to the invention, cooling and heat dissipation can be carried out on the switched reluctance motor and the controller more quickly and fully, so that the ventilation cooling efficiency of the reluctance motor and the controller circuit board is more effectively improved, and normal operation of the reluctance motor is effectively ensured. The motor comprises a reluctance motor, a shell, a heat dissipation shell and the like. And the shell is fixedly connected to one side of the reluctance motor. An electric push rod is started through a controller circuit board, the electric push rod drives a moving frame to move, then four guide rods move together and drive a sealing plate to move, the sealing plate does not block a dustproof net any more, external air can quickly enter the shell through the dustproof net, ventilation in the shell is enhanced
