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 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. Expesure to an ambient temperature in the range of -15?? to 40??, arid to an altitude which dose riot exceed 3300 feet. They are ideal far 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.
The terminal box is generally located in the middle of the frame. There are 3,6,9,and 12 out leads. The follow diagrams indicate the ways of connection. The length of leads 6 inches measured from frame surface. Terminal marking and connections should accord with MG1-2.62. There is grounding screw with grounding marking in the terminal box.
Terminal markings for Y and Delta connected Dual-voltage and Single-voltage motors.
*When the rated voltage value is not 460V,the value of full load current and locked-rotor current
are inversely proportional to 460V's current value
