【Abstract】 In order to improve the cutting efficiency of the roadheader and reduce the cutting energy consumption of the roadheader, the cutting frequency control technology of the roadheader is studied,the main body of the frequency converter and the variable frequency motor are designed,and jointly adjusted. A set of cutting frequency control system has been produced, and the system can be tested by the industry to achieve better cutting results.更多还原
