Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be understood that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 2, in an embodiment of the present invention, an intelligent switching circuit for a motor includes a controller CPU, a current transformer U1, a rectifier D1, a motor M1, and a relay JK 1. Specifically, the signal of the relay JK1 may be any one of 932-5VDC-SL, SJ-S-105DM and HF32F-005-HS 3. One end of a coil of the relay JK1 is connected to a control port JDQ1 of the controller CPU, and the other end is connected to a working voltage port VDDH of the controller CPU. One end of a contact switch of the relay is connected with the controller CPU through a current transformer U1, and the other end of the contact switch of the relay is connected with the motor M1 through a rectifier D1. The user can reach the purpose of motor M1 operation and stall through the mode that controller CPU controlled relay JK1 break-make, and the control mode is more intelligent, safety. In order to prevent the forgetting of shutdown and waste of electricity resources, the controller CPU is provided with a timer, and the contact switch of the relay JK1 is controlled to be switched off in a timing mode, namely the power supply input of the rectifier D1 is switched off, the motor M1 is switched off, and the function of timing shutdown of the motor is achieved.
Furthermore, two ends of a contact switch of the relay are connected with a peak absorption unit in parallel. The peak absorption unit comprises a capacitor C1 and a resistor C1. The peak absorption unit can better protect the rectifier D1 and the motor M1 when a contact switch of the relay is switched on, and the rectifier D1 and the motor M1 are prevented from being damaged due to overhigh voltage.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
