56 Frame Four-in-one Motor, Single-Phase is a revolutionary single-phase motor designed for diversified industrial scenarios, perfectly integrating the four-in-one innovative architecture (structure, starting method, protection and certification). Compared with traditional single-phase motors, its core advantage lies in the dual technology of capacitor start + capacitor run, which ensures efficient starting torque and smooth operation, significantly reducing energy consumption and noise. The motor adopts a rolled steel frame and a detachable foot, which takes into account both strength and installation flexibility, while the C-flange design simplifies integration with equipment. The unique high service factor (1.15) and F-class insulation (UL certification) enable it to perform well in harsh environments such as high temperature and dust. It has passed CSA, CUS and UL triple certifications and supports manual/automatic thermal protectors, with safety and compatibility far exceeding similar products. Whether it is a pump, fan, compressor or transmission system, this four-in-one motor redefines the standard of industrial power with its excellent energy efficiency and durability.
