The inverter is applicable in the environment of coal mine and places where is filled with explosive gas mixture such as methane and coal dust. It is used in the power supply system of AC 50HZ, voltage is 1140V or 660V, rated power is up to 560KW in the AC electric motor, it is designed wit new ideas, adopts the techniques such as frequency changing, vector control and explosion proof. Various controlling modes of FOC(Magnetic field directional vector control), senseless vector control and V/F control; operates among four quadrants, energy feedback function which has obvious effect; low speed with high torsion which is up to 200% as big as starting torsion.
