Abstract:In order to make the features more precise and sensitive of electric motor protection device, a kind of protection device based on single-chip is designed. Compared to traditional protection circuit, it is based on single-chip, making the system operated simply, controlled easily, sensitivity and reliability are all better than the latter. The whole package includes : MCU, data acquisition unit, the display unit and alarm. These devices improved the accuracy and usage of the whole protection circuit and achieves the motor over-current protection and over-load protection.
Keywords:electric motor  single-chip  protection circuit  over-load protection
