NEMA JM/JP single-speed, totally enclosed fan-cooled, continuous duty, low-voltage squirrel-cage three-phase asynchronous motors, conforming to U.S. NEMA MG1 standards, are specifically designed for close-coupled pump installations. They feature a rigid mounting frame and NEMA JM/JP pump shaft. The entire series of motors uses cast iron housings and a bearing locking structure at the shaft extension end to limit axial movement of the motor shaft. The motor efficiency meets U.S. NEMA EPACT and NEMA PREMIUM standards, with service factors of 1.15 and 1.25. The products are certified by U.S. CC and Canada CSA certifications.
