JKF Other models

The register lists here 20 versions with 0.75 to 110 kW, two- to four-pole, full-load efficiencies from 84.21 to 95.73% and at 75% load from 83.96 to 95.85%. Frame sizes run from 80 to 355, supply voltage is uniformly 400 V, protection is consistently IP55. Manufacturing is in Denmark, testing used test method A under AS/NZS 1359.5:2004; none of the 20 motors reaches a High Efficiency Level.

Spanning small frame size 80 up to large frame size 355, JKF covers a broad field of three-phase motors for pumps, fans and conveyors, mostly in the standard foot version B3.

When buying used, bearing condition and a checked insulation resistance of the winding, visible overheating marks on the terminal box and fan cover, the condition of shaft and key, and a legible nameplate with range, frame size and pole count matter; on the large frame sizes from 250 up, the lifting eyes and foundation fixing are also worth a look. Spares run through JKF's distribution.
