| Nema Type Motors |
| NEMA standard high
efficiency motors, are totally enclosed fancooled machines (IP54). This
series motors are designed and manufactured in accordance with NEMA standard
of U.S.A and C390-93 standard of Canada. They are of a novel style and
of excellent workmanship. And are characterized as reliability safety,
minimal temperature rise, high efficiency, low noise, low vibration, high
starting torque, etc.
The motors adopt design B and class F insulation. Their service Factor is 1.15. They are rated 208-230/460V,460V or 575V and 60Hz. The range of ambient temperature is from -15 oC to 40 oC, and the altitude dose not exceed 3300 feet above sea level. 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. |
