Introduction about the inverter chosen skill according to the load

Driven by electric motor load is different, the demands of frequency converter is different too, the following introduction about the inverter chosen skill according to the load:


1, Fan and water pump is the most common load: the demands of frequency converter is the most simple, as long as the converter capacity is equal to the motor capacity can (air compressor, water pump, mud pump, music fountain of rapid change to increase capacity).
2, Crane load: such great impact load characteristic is started, and therefore requires the inverter has a certain margin. At the same time, the weight down cubits, and the energy feedback, therefore to use the brake unit or use common bus Line.

3, Uneven load: some of the load is light, sometimes sometimes heavy, at this time should be according to the heavy load conditions to select the inverter capacity, such as rolling mill machine, crushing machine, mixer, etc.
4, Large inertia loads, such as centrifuge, punch press, cement rotary kiln, such load inertia is very big, so may oscillation when starting, motor slowdown energy feedback..Should use a larger frequency converter capacity to speed up the start, avoid oscillation. Cooperate with brake units to eliminate feedback electricity.
