NEMA
STANDARD SERIES SINGLE PHASE ASYNCHRONOUS ELECTRIC MOTOR
GENERAL 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 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.
 
TERMINAL BOX
There are 3, 6, 9 and 12 outleads in the terminal box.
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 MG 1-2.62. There is grounding screw
with grounding marking in the terminal box.
Terminal markings for Y and Delta connected Dual-voltage and Single-voltage
motors.
