全系列电机采用铸铁材质外壳，轴伸端轴承锁紧结构，以限制电机轴伸轴向窜动。电机效率符合美国NEMA EPACT、NEMA PREMIUM标准，使用系数为1.25。产品通过美国CC认证和加拿大CSA认证。
NEMA JM/JP are single speed, totally enclosed, fan-cooled, continuous working duty, low voltage cage type three phase induction electric motors which conform to America NEMA MG1 standard and are designed for tight coupling pump. The motors have rigid installing frames and MENA JM/JP pump shafts. All series motors adopt casting iron frames, locked-bearing structure at driving end to limit shaft extension axial float. The efficiency meets America NEMA EPACT、NEMA PREMIUM standard, service factor is 1.25. The motor has passed America CC certification and Canada CSA certification.
