Abstract:
Disclosed in the present invention is a control system of a direct-current brushless non-inductive motor of a running machine, specifically relating to a control system capable of automatically regulating the rotating speed of the motor to the minimum when the running machine is started. After a contact switch is connected to a power supply, a gear and a one-way wheel are driven by a rack plate to rotate, and the one-way wheel drives a bevel gear and a driven shaft to rotate by means of a bevel gear ring so as to drive a speed regulation wheel to automatically regulate the rotating speed to the minimum. A switch button is movably connected above a box body; the switch button is electrically connected to a transformer by means of a wire; an electromagnet is fixed above a fixed plate; a sleeve is fixed in the box body; a telescopic rod is fitted above the sleeve; a movable plate is fixedly connected to the upper end of the telescopic rod; the contact switch is fixedly connected below one side of the movable plate; the rack plate is fixedly connected below the side of the movable plate opposite to the contact switch; the rack plate is meshed with the gear; the gear is rotatably connected to the lower end of a suspension rod; the one-way wheel is rotatably connected inside the box body; the one-way wheel is connected to the gear by means of a transmission belt; an outer wheel is provided outside the one-way wheel.
