Moto Technik CDF5.5 B3

The register lists five versions with 5.5 to 55 kW rated output, two to six poles, and an efficiency span of 84.6 to 93.35% at full load and 84.9 to 93.45% at 75% load. Frame size ranges from 132 to 280, 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, CDF5.5/B3 covers the mid to upper band of classic industrial drives, for example pumps, compressors, conveyors and fans, 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.
