Motor starting modes include: full voltage direct starting, auto decompression starting, y-δ starting, soft starter, frequency converter.
Full pressure direct starting:
Full voltage direct starting can be considered when both capacity and load of the network allow full voltage direct starting. The advantages are convenient control, simple maintenance, and more economical. Mainly used for small power motor starting, from the point of view of energy saving, more than 11kW motor should not use this method.
Automatic vacuum starting:
Using multiple tap decompression of autotransformer can not only adapt to the needs of different load starting, but also get larger starting torque. It is a kind of decompression starting mode which is often used to start large capacity motor. Its biggest advantage is that the starting torque is large. When the winding tap is at 80%, the starting torque can reach 64% of the direct starting. And the starting torque can be adjusted by tapping. It is still widely used today.
