Motors

• Steel fan cover for optimum strength.
• Small size, high strength non-sparking fan reduces noise and enhances efficiency. Fan is keyed to shaft.
• Heavy-duty cast iron frame, end plates and conduit box.
• Alloy aluminum nameplate with standard information on motor efficiency, wiring diagram, bearing size etc. See last page for details.
• Copper magnet wire, high grade electromagnetic steel stator, lower resistance and FR losses, high efficiency design for 1.15 service factor, Class F insulation.
• Cast aluminum rotor dynamically balanced, for reduced vibration and noise. Surface painted with a semigloss polyester finish.
• Ball bearings meet all standards. 143TC-256TC frame motors use permanently lubricated ball bearings while 284TC frame and larger motors are regreasable.
• Lubrication fittings on each end of motor (284TC frame and larger), Lithium base grease is used with range of -22 to 230 (-30 to 110) ambient temperature.
• One-way, corrosion resistant condensate drains to release condensation and moisture from the housing.
• Oversized cast iron conduit box, double gaskets, can be rotated in 90?increments. NPT threaded entrance. Leads are extra long and permanently marked. Motors 213TC and larger are suitable for wye-delta starting as standard.
