Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with embodiment, further set forth the utility model.

As shown in Figure 1, the described a kind of control circuit that is applicable to jigging machine of the utility model, it comprises mainly and comprising: power supply, controller system, IPM module and driving, position detecting five parts of communicating by letter with RS485.

As shown in Figure 2; Ling Yang 16 frequency conversion chips SPMC75F2313A and power device intelligent object IPM are used in the design of controller system; Realize driving and speed governing to three phase winding DC Brushless Motor in conjunction with basic driven algorithm through power device intelligent object IPM, in program development process, the Probe through SPMC75F2313A connects embedded in-circuit emulation; Reduced the difficulty of driving and system development, improved production efficiency, accelerated development progress.

As shown in Figure 3, the coupling relation of IPM module convenience and simplification microcontroller and controlled device, IPM module and driving autoprotection function like current protection, voltage protection, temperature protection etc., have improved the reliability of system.
