Impact crusher 160 kW how with the inverter?
(2) When selecting the inverter, the actual motor current value should be used as the basis for selecting the inverter. The rated power of the motor can only be used as a reference.
Therefore, in the choice of motor and inverter, should take into account the situation, the appropriate margin to prevent the temperature rise is too high, affecting the motor life.
Therefore, the power supply to the motor with the inverter compared with the power grid power supply compared to the motor current increased by 10% and the temperature increased by about 20%.
Also should take full account of the output of the inverter contains high harmonics, will cause the motor power factor and efficiency will be bad.
1) Select the inverter according to the load characteristics. If the load is constant torque load, select the siemens MMV / MDV inverter. If the load is fan, the pump load should be selected siemens ECO inverter.
