  • IEC frames 90, 100, 112, 132 and 160
  • Poles 2, 4, 6, 8/2 and 12/4
  • Voltage Δ/Y 230/400V 50/60Hz
  • Brake coil voltage (VDC) 0.45 UAC (other on request)
  • Braking torque 1.5 x rated torque or higher
  • Protection up to IP65
  • Insulation F, H
  • 40 deg C ambient rating
  • IC410, IC411, IC416 cooling
  • S4-40% (240 s/h), S4-20/40% (240 s/h)

The lifting three-phase electric motors are designed for application in the main motion of the rope and chain hoists. The brake of the cylindrical motors is electromagnetic, DC, and non-adjustable. Lifting motors are produced in different joining dimensions based on their application. Forced ventilation is also available if needed.
