Motor power supply capable of preventing overheating and burning

Abstract

The invention discloses a motor power supply capable of preventing overheating and burning. The motor power supply comprises a voltage conversion circuit, a soft starting control circuit and a currentdetection control circuit and is characterized in that the voltage conversion circuit is connected with the soft starting control circuit and the current detection control circuit, the soft startingcontrol circuit is further connected with the current detection control circuit, and the current detection control circuit is further connected with a DC motor M. In the motor power supply capable ofpreventing overheating and burning, the overcurrent protection function of the DC motor is achieved by a logic gate controller combined with a relay, the overcurrent influence caused by starting largecurrent on the DC motor can be effectively prevented, so that the risk that a coil in the motor is over-heated is reduced, meanwhile, the function of interference resistance is also achieved, and themotor power supply has the advantages of stable performance and good application effect and is convenient to use.

Description

technical field [0001] The invention relates to a motor circuit, in particular to a motor power supply for preventing overheating and burning. Background technique [0002] Due to the advantages of uniform running speed and good mechanical strength, DC motors are widely used in various mechanical equipment and power components of household appliances. Common applications include electric fans, ceiling fans, generators, etc. Currently, DC motor circuits commonly used in the market are mostly The structure is complex, the function is single, and the DC motor is easy to cause its internal coil to overheat due to overcurrent, which will cause burning and economic loss, so it needs to be improved. Contents of the invention [0003] The object of the present invention is to provide a motor power supply that prevents overheating and burnout, so as to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present inventio...
