  • available with IP55 / IP65 or IP23 protection degree
  • IE2, IE3, IE4 and non-IE high-performance motors with variable or fixed speed.
  • designed to operate both directly powered by the network and controlled by a speed variator, ensuring a very high level of efficiency.
  • Motors designed to comply with both European and North American energy regulations.
  • High reliability - Robust housing, with front and rear cast iron flange which ensures better
  • Energy saving
  • Fast delivery times
  • Use of standard motors: multi-voltage / multi-frequency, compliance with international standards

Mechanically robust

  • Robust design, tested with simulations and tests
  • Cast iron shields sized (including for aluminum motors)
  • Machine stator unit machined on a spindle, to guarantee perfect concentricity of the motor's magnetic axis
