TECHNICAL DATA

Aluminum Motors

Three-Phase IEC Motors – Frame Sizes IEC 56 to IEC 160

Voltage Range

  • Up to 3 kW (4 HP):
    380–420 V / 220–240 V (Y/Δ) – 50 Hz

  • From 4 kW (5.5 HP) and above:
    660–725 V / 380–420 V (Y/Δ) – 50 Hz

Main Applications

  • Fans

  • Pumps

  • Gearboxes

  • Compressors

  • Textile machinery

  • Food industry

Standard Features

  • Industrial series aluminium housing motors, lightweight and robust

  • Protection degree: IP55

  • Insulation class F, with temperature rise limited to 80°C

  • Removable feet, allowing terminal box positioning on right or left-hand side

  • Terminal box rotatable 180° for flexible cable entry

  • SKF or NSK bearings for high reliability

  • Cast iron endshields for frame sizes 80–160

  • Standard color: RAL 5010 (Blue)

Optional Features

  • Special voltages and frequencies on request

  • Insulation class H for higher thermal performance

  • Brake kits available for all motor sizes

  • Forced cooling for constant torque operation with frequency inverters

  • Higher protection classes: IP56 / IP65

  • Cast iron flanges and endshields for added robustness

  • PTC or PT100 sensors in windings for thermal monitoring

  • Reduced frame motors (non-IEC) for compact designs

  • Anti-condensation heaters to prevent moisture buildup

  • Roller bearings on drive end for high radial loads

  • Double shaft extensions for dual-output needs

  • Custom cable executions, with terminal box or direct cable connection

  • Epoxy resin encapsulated terminal box for harsh environments

  • Epoxy resin encapsulated windings for enhanced insulation

  • Silicone encapsulated terminal box for extra protection
