That why some single phase motor as long as a capacitor operation. How to start? Single capacitance and single-phase capacitor motor small electric fan motor basic double with double values, the difference lies in the single-phase electric motor for double value just starting with the raised large and increase the starting torque capacity of capacitance, Starting when starting and running capacitors are connected to the www.facebook.com/guohong.trading motor winding, after perkins diesel generator set starting, starting capacitance disconnect, this task is performed by automatic centrifugal open, single-phase motor double value Commonly used in bigger starting power equipment, such as air compressor, etc...
