NEMA standard high efficiency three-phase induction motors
|
|
DESCRIPTION |
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.
TERMINAL BOX
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.
