| By analyzing the problems and shortages of the microcomputer protector for the motor that is used in sites at present, we bring forward a new method for digital motor protector, which is based on the DSP hardware platform. This microcomputer protector for the motor uses the DSP56F807 which is the series of the Motorola's DSP56800 as its kernel processor. The chipset not only has single chip's great steering capability but also has digital signal processor's arithmetic capability. It also has reasonable price and high performance. We use popular C language as main program language. At the same time, we optimize the present protection criterion and principle, and add some protection functions. To make the protector operates more quickly and reliably, we apply software and hardware technology into anti-interference method. The digital motor synthetic protector includes protection, measurement, communication and all. |
