The invention discloses a contactless switch control motor circuit, relating to the technical field of manufacturing of electrical equipment. The contactless switch control motor circuit comprises a main loop and a control loop; the main loop comprises a knife switch and a fuse; the control loop comprises a first button, a second button and a conversion switch; the knife switch, the fuse, a contactless switch and a motor are connected in series, so that a main loop circuit is formed; wiring terminals are arranged on the contactless switch; two ends of the first button are respectively connected with the first wiring terminal and the second wiring terminal of the contactless switch; two ends of the second button are respectively connected with the third wiring terminal and the fourth wiring terminal of the contactless switch; and the conversion switch is respectively connected with the fifth wiring terminal, the sixth wiring terminal and the seventh wiring terminal of the contactless switch. According to the contactless switch control motor circuit disclosed by the invention, the problem that a power grid is interfered due to the fact that heavy current is generated by a mechanical switch at the moment of being closed and opened can be solved.
Description
technical field [0001] The invention relates to the technical field of electrical equipment manufacturing; in particular, a non-contact switch control circuit 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 circuit, which can solve the problem that the mechanical switch generates a large current...
