The four TYJVFT-900M4-32(1000/3300) high-voltage permanent magnet direct drive frequency conversion integrated machines of the belt conveyor are respectively set as the main machine (1#) and the slave machine (2#, 3#, 4#). High-speed bus communication is adopted between the main machine and the slave machine, which can automatically adjust its own output to achieve dynamic power balance.

Solution advantage ////////

☆ With 4 sets of driving devices, "with 3 to 1" has the application potential of conveyor speed and efficiency, and the maximum allowable transport capacity is increased by more than 25%;

☆ Direct drive permanent magnet frequency conversion integrated machine eliminates reducer, improves transmission efficiency, eliminates maintenance workload such as reducer oil change, so that the underground working conditions tend to be oil-free and less human;

☆ It has the characteristics of small running current and low temperature rise, remarkable energy-saving effect, and the average energy-saving rate is >28%, which is in line with the transformation target trend of energy saving and consumption reduction;

☆ The permanent magnet direct drive frequency conversion integrated machine device used in this scheme has universal compatibility with 40% of the high-voltage combined frequency converter devices used in fully mechanized mining face.
