FC 200 Cast Iron:

– This is Explosion Proof quality cast iron (higher density), thus stronger with more efficiency and lower vibration levels.

STATOR CASTING FRAME:

– Uni-body construction - Greater strength and no “Hot Spots”

TERMINAL BOX:

– Oversize Cast Iron Terminal Box on most lines fitted with O-Ring rubber sealing gaskets and filled with resistant sponge-like material to seal the lead path through the frame and Rotatable by 90º turns.

SHAFT MATERIAL:

– 4140 High Tensile Steel on Frame 404T and up (IV, VI and VII pole).
– 1045 Carbon Steel on frames 143T to 365T
– 316 Stainless Steel on Jet Pump motors (TEFC and ODP)

BEARING:

– Best Quality Bearings (SKF, NSK)
– Enlarged grease cavities and double strength bearings retainer caps.

GREASE:

– All frames ESSO/EXXON POLYREX EM - blue color and is a polyurea based grease (achieved a lubrication life of more than 700 hours at 177ºC (350ºF)). Other special greases available upon request.

DESIGN TEMP. RISE:

– 80ºC (Class “B”) temperature rise

WINDING IMPREGNATION:

– Class “H” Resin for all motors.
– Resin continuous flow (trickle) on all windings-364T and up.

WINDING INSULATION:

– Class F (155ºC) Insulation System Tropicalized windings

DEGREE OF PROTECTION TEFC (IP55):

– IP55 (Severe Duty) (Water projected by a nozzle against the enclosure from any direction shall have no harmful effect)
– V-ring Seals (prevents water and dust entering the motor around the shaft)
– Tachonite Labryinth Seals on TEFC (Also available)
– Drain Plugs (to remove excess water that results from condensation) – Gasketed conduit box

SERVICE FACTOR:

– 1.25 on NEMA TEFC motors 1HP to 100HP and 1.15 on 125HP and up

PAINTING:

– Internal/External parts painted with anti-corrosive alkidic resin base paint

HARDWARD:

– All hardware components are galvanized

FLEXIBILITY:

– F1 and F2 mounting (mechanically reversible)

– Horizontal or Vertical mount - Circlips on opposite drive end - frames 324T and up

AREA CLASSIFICATION:

– Class I, Division II, Group C and D listed on nameplate Designed for intermittent hazardous environments (except explosion proof)

BALANCING:

– Rotating parts dynamically balanced According to IEC 34.14 (more stringent than NEMA standards)

STARTING:

– Wye Delta starting to reduce inrush current standard for frames 254T and above in most lines.

TORQUES:

– Locked Rotor and Breakdown Torques that exceed Design C for almost ALL ratings (NEMA Design C requires significantly higher LRT and BDT than NEMA Design B, the standard for most all other manufacturers)
