Detailed description of the invention
Fig. 1 is the electrical block diagram of the utility model.
Specific embodiment
Below by specific embodiment, the technical solution of the utility model is described in further detail.
As shown in Figure 1, a kind of high voltage direct current control circuit for magnet steel motor, including resistance R1, resistance R2, capacitor
C1, capacitor C2, capacitor C3, capacitor C4, capacitor C5, capacitor C6, diode D1, diode D2, diode rectifier bridge BR1 and relay
Device J, the both ends of resistance R1 are separately connected power supply, and capacitor C1 is connected in parallel on the both ends of resistance R1, and one end of resistance R1 passes sequentially through often
Switch MQS1 connects the anode of diode D1 and an input terminal of diode rectifier bridge BR1, relay with normally closed switch MQS2
The contact circuit J1 of device J is connected to the both ends of normal open switch MQS1, and the cathode of diode D1 passes sequentially through resistance R2 and capacitor C2
The other end of resistance R1 is connected, for the coils from parallel connection of coils of relay J at the both ends of capacitor C2, another of diode rectifier bridge BR1 is defeated
Enter the other end of end connection resistance R1, two output ends of diode rectifier bridge BR1 are separately connected both ends and the conduct of capacitor C6
The output end of high voltage direct current control circuit, capacitor C3 and diode D2 are connected in parallel on the both ends of capacitor C6, capacitor C4 and capacitor respectively
The both ends of capacitor C6 are connected in parallel on after C5 concatenation.
In use, power supply passes through normal open switch MQS1, normally closed switch MQS2, diode D1 after pressing normal open switch MQS1
It is that capacitor C2 charges and the coil of relay J is powered, work of the normal open switch MQS1 in contact circuit J1 after loosing one's grip with resistance R2
With lower holding attracting state, power good input diode rectifier bridge exports DC power supply after full-wave rectification.It is normally closed when pressing
Relay coil power loss when switch MQS2, contact circuit J1 are disconnected, and power loss, motor stall diode rectifier bridge BR1 simultaneously.Work as electricity
When machine powers off during operation, due to relay coil power loss, contact circuit J1 is disconnected, and normal open switch MQS1 is by closed state
It disconnects, at this moment just plays a protective role, it is necessary to re-press normal open switch MQS1, relay coil is made to re-power self-insurance
Holding could work normally.
