Moto Technik lists the CDF4/B3/4 as a three-phase induction motor. The rated output is 4 kW. The motor is four-pole, which at 50 Hz gives a synchronous speed of 1,500 rpm. The rated voltage is 415 V. The housing is frame size 112 M in foot-mounted form. The protection class is IP55. The efficiency is 84.2 per cent at full load, 84.5 per cent at 75 per cent load and 83.1 per cent at half load. The motor weighs 43 kg. At full load it delivers 26.6 Nm. Mounting arrangements to IEC 60034-7: B3, B5, B14, B35 and B34. The motor is built in China. The data is based on the Australian MEPS registration under standard AS/NZS 1359.5:2000 (Legacy); measured to AS 1359.102.1:1997. Rated output across the Moto Technik range ranges from 0.75 to 160 kW; the CDF4/B3/4 sits at the bottom of that range with 4 kW. Its immediate neighbours are the MS3/B3/6 below it with 3 kW and the CDF5.5/B3/2 above it with 5.5 kW. 88 Moto Technik models are on record. The model is listed under Electric motors. 24 verified figures from 1 source are on file.

Moto-Technik – other models: the collective page of MEPS-registered three-phase motors outside the named ranges, manufactured in China, frame sizes 90 to 315, 0.75 to 160 kW, 2- to 6-pole

This page gathers the Moto-Technik three-phase motors the Australian energy-efficiency register could not assign to a named range. No confirmed data on the company itself is available. The type designations, such as CDF0.75/B3/2 or CDF160/B3/4, follow the scheme CDF<output in kW>/<mounting code>/<pole count>, meaning output and mounting form are written directly into the name.

The register lists here 60 versions with 0.75 to 160 kW, two- to six-pole, full-load efficiencies from 73.2 to 95.85% and at 75% load from 73.4 to 95.25%. Frame sizes run from 90 to 315, all motors are recorded with IP55 protection. China is recorded throughout as the manufacturing country. Testing mostly followed the older 2000 Legacy AS/NZS 1359.5 standard (51), alongside the 2004 version (9), always with test method B; of 60 motors, only 2 carry a documented High Efficiency Level, the remaining 58 stay unclassified.

With output written directly into the type name, the range targets users who select motors chiefly by kilowatt rating, used mainly in pumps, fans and general drive tasks in the value-priced segment.

When buying used, what matters is bearing condition and a checked insulation resistance of the winding, visible corrosion on the terminal box and fan cover, the condition of shaft and key, and a legible nameplate with output and pole count; since almost the entire range comes from older series registered under the Legacy standard, inverter suitability should be checked individually. Spares and support depend on the distribution channel.

Frequently asked questions

How much power does the Moto Technik CDF4/B3/4 have?

The Moto Technik CDF4/B3/4 delivers 4 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.
