(Efficiency classes of single-speed, three-phase, squirrel-cage induction motors) Efficiency classes

There is an accelerating trend among major countries to adopt high-efficiency standards (legal regulations and policies) for motors (3-phase induction motors) in order to conserve the global environment and prevent global warming.
Japan has also mandated a "Top Runner System," which came into effect on April 1, 2015 after the amendment and notification* of the "Act on the Rational Use of Energy (Energy Conservation Act)."


  • High-efficiency

    Top-runner standard value compliant!

  • Energy saving

    Running cost greatly decreased!

  • Easy replacement*1

    Same frame size and connecting dimensions as standard motors!

  • Capable of operation in combination with an inverter

  • Compliance with the environmental burden material (including 6 substances) of the European RoHS Directive*2

  • Non-asbestos material specifications

  • With loosened brake handle

  • Easy brake maintenance

  • Adoption of plastic thin-type terminal box


*1is based on comparison with our previous products

*2includes lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl (PBB) and polybrominated diphenyl ethers (PBDE)
