Moto Technik CDF1.5 B3

The register lists here 6 versions with 1.5 to 15 kW rated output, 2- to 6-pole, at a voltage of 415 V. Full-load efficiency ranges from 77.4 to 89.85%, and at 75% load from 77.7 to 89.95%. Frame sizes run from 90 to 180, and all six motors carry IP55 protection. Testing followed the legacy standard AS/NZS 1359.5:2000 using test method B.

With frame sizes up to 180, the CDF1.5/B3 range covers the mid power band of three-phase foot-mounted motors used for pumps, fans and medium-duty conveying equipment. The range is manufactured in China.

When buying used, what matters is bearing condition and a checked insulation resistance of the winding, visible overheating marks on the terminal box and fan cover, and a legible nameplate with frame size, pole count and protection rating. The mounting codes B3, B5, B14, B34 and B35 show the motors can also be fitted in other positions via adapters. Spares run through the relevant distributor.
