NEMA standard high efficiency motors are totally enclosed fan cooled machine(IP54).This series motors are designed and manufactured in accordance with NEMA standard of U.S.A and C390-93 standard of Canada. These motors are of a novel style and of excellent workmanship. The motors are characterized as reliability safety, minimal temperaure rise , high efficiency, low noise. low vibration. high starting torque, etc. The motors adopt design Band class F insulation, Their service factor is 1.15. They are rated 208-230/460V, 460V or 575V and 60Hz. Exposure to an ambient temperature in the range of -15 to 40, arid to an altitude which dose not exceed 3300 nfeet. They are ideal for application with no special requirement, They can be used to drive various kinds of mechanical equipment. This series motors can be specially manufactured on request, such as T, TC, TD or H insulation class, different voltage, different frequency, etc.
