SERVOMECH Linear Actuators 7.1 AC 3-phase electric motors AC asynchronous 3-phase motors, totally enclosed, fan-cooled, with or without brake, made by Italian manufacturers according to IEC standards. Dynamically balanced rotor, high pressure die-casting housing with fins in aluminium alloy. Standard: insulation class F, protection class IP 55. On request: insulation class H and/or higher protection class. On request: tropicalised winding for ambient with high temperature and humidity. On request: thermal protection devices. On request: brake motor. For more technical information and details, please, refer to manufacturers catalogue. 7.2 AC 1-phase electric motors AC asynchronous 1-phase motors, totally enclosed, fan-cooled, with or without brake, made by an Italian manufacturers according to IEC standards. Dynamically balanced rotor, high pressure die-casting housing with fins in aluminium alloy. Balanced stator windings for clockwise and anti-clockwise running without vibrations. Condenser supplied with motor, with increased capacity for higher starting torque. Standard: insulation class F, protection class IP 55. On request: insulation class H and/or higher protection class. On request: thermal protection devices.
