Embodiment Construction
[0013] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
[0014] figure 1 with figure 2 The non-contact switch control motor method shown includes a control box, a knife switch QS, a fuse FU and a non-contact switch WKP are installed in the control box, and the first button SB1 and the second button are installed on the door of the control box. Two buttons SB2 and changeover switch SA; knife switch QS, fuse FU, non-contact switch WKP and motor M are connected in series to form a main loop circuit; non-contact switch WKP is provided with connecting terminals, and the two ends of the first button SB1 are respectively connected to The first connection terminal J1 of the non-contact switch WKP is connected to the second connection terminal J2, and the two ends of the second button SB2 are respectively connected to the third connection terminal J3 and the fourth connection terminal J4 of the non-contact switch WKP...

The invention discloses a method for controlling a motor through a contactless switch, and relates to the technical field of electrical equipment manufacture. A change-over switch is turned to a manual gear, a contactless switch is in a manual control work state, a first button is pressed down to set a 7555 chip to output a high level, a triode is conducted to make a relay coil be closed, a normally open contact of the relay is closed, a bidirectional silicon controlled rectifier is conducted, and the motor is powered on to rotate; a second button is pressed down to reset the 7555 chip to output a low level, the triode is cut off to make the relay coil be powered off and released, a normally open contact of the relay is opened, and the motor is powered off and stops the service; the change-over switch is turned to an automatic gear, and the contactless switch is in an automatic work state; whenever the 7555 chip outputs a high level, the relay is closed, and the motor is started; whenever the 7555 chip outputs a low level, the relay is released, and the motor stops. According to the invention, the problem that when a mechanical switch is closed and opened, a large current is generated, and the power grid is interfered can be solved.
Description
technical field [0001] The invention relates to the technical field of electrical equipment manufacturing; in particular, a non-contact switch WKP control method for motor control. Background technique [0002] The motor is an indispensable part in industrial production. Many devices can only be driven by the motor. In order to control the motor, people have designed many circuits for controlling the motor. A simple motor control circuit is to set a For mechanical switches such as knife switches or circuit breakers, the operator manually controls the opening and closing of the knife switch or circuit breaker to control the motor; because the mechanical switch will generate a large current at the moment of opening and closing, which will interfere with the power grid . Contents of the invention [0003] The purpose of the present invention is to provide a non-contact switch control motor method, which can solve the problem that the mechanical switch generates a large curre...
