NEMA JM/JP single-speed, fully enclosed, self-fan-cooled, continuous-working, low-voltage cage-type three-phase asynchronous motor conforms to American NEMA MG1 standard, which is specially designed for tightly coupled pump installation, with rigid mounting base and NEMA JM/JP pump shaft. The whole series of motors are made of cast iron shell, and the shaft extension end bearing is locked to limit the axial movement of the motor shaft extension. The efficiency of the motor meets the standards of NEMA EPACT and NEMA PREMIUM in the United States, and the service coefficients are 1.15 and 1.25. The products have passed the US CC certification and the Canadian CSA certification.
