| Mechanical Features |
Open drip-proof construction, cooling air exhausts at the shaft end for maximum cooling. Oversized locked bearing on shaft end limits axial shaft movement. Drip covers are available as accessory kits for 143-5JM and 182- 4JM motors for the correct kit. Some 182-4JM frame motors have enclosed endshields as standard with frame vents meeting the 12ยบ drip-proof requirement. No drip cover is needed, or shown in the table, for these motors. |
