Moto-Technik CDF7.5/B3 – three-phase motor with foot mounting: frame sizes 132 to 315, two- to six-pole, 7.5 to 75 kW, IP55, tested to AS/NZS 1359.5
CDF7.5/B3 denotes a three-phase motor range with foot mounting (B3), where the trailing digit in the type designation – /2, /4 or /6 – indicates the pole count; the register confirms exactly this span of two to six poles for the five versions listed. The model designation CDF7.5 marks the lowest output step of this range, but in practice the register covers the whole range from 7.5 to 75 kW, since larger frame sizes up to 315 are listed under the same model family.

The register lists five versions with 7.5 to 75 kW rated output, two to six poles, and an efficiency span of 86.85 to 93.95% at full load and 86.36 to 93.55% at 75% load. Frame size ranges from 132 to 315, protection is IP55 throughout, and the voltage entry is 415 V. Manufacturing takes place in China, tested under the older AS/NZS 1359.5:2000 standard, using test method B throughout. The mounting code for all versions is the foot-flange combination B3/B5/B14/B34/B35.
With this output span, CDF7.5/B3 covers the upper band of classic industrial drives, for example larger pumps, compressors and conveyors, where a robust foot mounting with optional flange fixing is required.
When buying used or swapping, check bearing condition, insulation resistance of the winding, visible overheating traces on the terminal box and fan cover, and a legible nameplate showing frame size, pole count and output. Since the range covers several output steps under a similar name, the actual frame size should be checked on the nameplate before purchase.

The Moto Technik CDF7.5/B3/2 delivers 7.5 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.
