The successful test of Shanchuan motor is the symbol that Shanchuan Motor permanent magnet motor teststand is put into formal trial operation, indicating that the whole series products of Shanchuan Motor self-starting permanent magnet motor have been placed on the market step by step. At present, all Shanchuan Motor ultra-high efficient self-starting permanent magnet motors（0.55KW~7.5KW aluminum shell motor) have been put into mass production. We have obtained very good sales performance in the supporting projects and energy-saving renovation projects in ceramic machinery and other industries, so we have been highly evaluated by related factories and customers. Shanchuan Motor 2-pole 37KW self-starting permanent magnet motor differs from ordinary permanent magnet motor due to its characteristic of direct starting without the need of frequency converter. Its finalized mass production means the arrival of a motor revolution for such industries as air compressor. Its advantages of high efficiency and high service coefficient, large torque, easy starting and efficient energy saving will inevitably replace asynchronous motors and become the first choice of motors that are used to support and renovate air compressors in the future.
