The invention discloses a contactless switch control motor device, and relates to the technical field of manufacture of electrical equipment. The contactless switch control motor device comprises a control box, wherein a knife switch, a fuse and a contactless switch are mounted in the control box, and a first button, a second button and a change-over switch are mounted on a box door of the control box; the knife switch, the fuse and the contactless switch are serially connected with a motor to form a primary loop circuit; wiring terminals are arranged on the contactless switch, both ends of the first button are respectively connected with the first wiring terminal and the second wiring terminal of the contactless switch, both ends of the second button are respectively connected with the third wiring terminal and the fourth wiring terminal of the contactless switch, and the change-over switch is separately connected with the fifth wiring terminal, the sixth wiring terminal and the seventh wiring terminal of the contactless switch. The contactless switch control motor device disclosed by the invention can solve the problem that a mechanical switch generates large current at the breaking-closing moments to generate interference on a power grid.
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 device, which can solve the problem that the mechanical switch generates a large current ...
