Steel fan cover for optimum strength.
2. Small size,
high strength non-sparking fan reduces noise and enhances efficiency. Fan
is keyed to the shaft.
cast iron frame, end plated and conduit box.
copper nameplate with standard information on motor efficiency, wiring
diagram, bearing sizes etc.
Plus TM 200 C inverter spike resistant magnet wire, high grade electromagnetic
steel stator, lower resistance and I2R losses, high efficiency design,
inverter rated insulation system.
6. Cast aluminium
rotor dynamically balanced, for reduced vibration and noise. The surface
is painted with a semigloss polyester finish.
meet all standards. 143T-256T frame motors use double shielded ball bearings
while 284T frame and larger motors have greaseable bearings with bearing
caps to protect against entry of grease into the motor.
fittings on each end of motor (284T frame and larger). Lithium base grease
is used with range of -30C~+110C ambient temperature.
shafts slinger protects bearings by repelling moisture and other contaminants.
corrosion resistant condensate drains to release condensation and moisture
from the housing.
cast iron conduit box, double gaskets, box can be rotated in 90° increments.
NPT threaded entrance. Leads are extra long and permanently marked, 404T-405T
frame motors have 12 leads, suitable for wye-delta starting.
