Novel fusion proteins comprising PP14 are disclosed. The washing machine includes an outer shaft for rotating the main drum, an inner shaft for rotating the sub drum, being disposed inside the outer shaft, and a driving motor having a stator, an outer rotor connected to the inner shaft and rotatable outside the stator, and an inner rotor connected to the outer shaft and rotatable inside the stator. This enables the self-calibrationtrimming to be handled completely within a product, such as a radio telephone, and no external instruments or software are needed for trimming.
