JKF – other models: the collective page of Danish-made three-phase motors outside the named ranges, HMA3 and HMC3 scheme, frame sizes 80 to 355, 0.75 to 110 kW, 2- to 4-pole
This page gathers the JKF three-phase motors the Australian energy-efficiency register could not assign to a named range. The designations in the register follow the scheme of range code HMA3 or HMC3, frame size, build length and pole count, such as HMC3-200L1-2 for the HMC3 range, frame size 200, length L1, two-pole; some models are recorded in lower case, such as hma3-112m1-2.

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.

Frequently asked questions
How much power does the JKF HMC3-280S-2 have?
The JKF HMC3-280S-2 delivers 75 kW.
What to check before buying
- Match the data plate against the order: frame size, mounting and rating have to agree.
- Check the ingress rating against the installation site — outdoors or in dust the demands differ.
- Hold the mounting form and dimensions against the existing seat before ordering.
- The pole count sets the speed — when replacing an older unit, compare this first.
- For used units, ask about winding condition and bearing play.
- Ask about parts availability for this series — the running costs hang on it.
