Description
Technical Field
The utility model relates to a motor overload protection technical field especially relates to a motor control circuit diagram.
Background
The motor overload protection generally means that a thermal relay is arranged in a main circuit of a motor, when the motor is overloaded, the thermal relay acts, a normally closed contact cuts off a control circuit, a normally open contact is closed to switch on an indicator light, after overload is eliminated, the motor returns to normal work after being cooled, in order to avoid the problem that the motor is overloaded, the motor is often operated at a power smaller than a constant power, but the motor is required to be operated in a state close to a full load state when the motor is required to be operated in the aspect of improving economic benefits, the overload problem is easy to occur when the existing motor is close to the full load work, after the overload, the motor is required to be shut down, the production can be influenced, and therefore the motor is required to be operated for a long time.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem that the motor in the prior art is easy to overload when working under the condition of approaching full load, and providing a motor control circuit diagram.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
designing a motor control circuit diagram, which comprises a wire inlet end and a wire outlet end, wherein the wire outlet end is electrically connected with an electromagnetic valve, the electromagnetic valve is electrically connected with a static relay, the static relay is electrically connected with a first relay, and the first relay is electrically connected with the wire inlet end; the outlet end is electrically connected with a second button, and the second button is electrically connected with the first relay; the second button is electrically connected with a first button, and the first button is electrically connected with a first relay; the first button is electrically connected with a second relay, and the second relay is electrically connected with a wire inlet end; the outlet end is electrically connected with a switch, and the switch is electrically connected with a second relay; the static relay is electrically connected with a motor.
Preferably, the first relay and the second relay adopt time relays.
Preferably, the switch is a magnetic induction switch.
Preferably, the first button is a normally open button, and the second button is a normally closed button.
The utility model provides a pair of motor control circuit diagram, beneficial effect lies in:
the utility model discloses a set up static relay and be used for protecting the motor, prevent that the motor from transshipping, through setting up normally open button, normally closed button, two relays, magnetic switch, solenoid valve for the motor of being connected with static relay electricity can be close to work under the full load state.
