5% rated voltage Ambient temperature up to +40centigrade Installation altitude up to 1000 meters above sea level STRUCTURAL CHARACTERISTICS Dynamically balanced MOTOR SHAFT with double-shielded life-lubricated bearings(working life more than 5,000 hours). Open and self-ventilated induction MOTOR,designed for continuous duty. -The stator pack in made of low-leakage magnetic laminations(2.63 Watt/kg). -Stator windings are manufactured using wire with double class H insulation;heads carefully bound and shaped by pressure. Lmpregnation is done in a continuous cycle by PREHEATING-IMMERSION BAKING with extremely pure ideally-polyester resin, motors insulation is class B. This gives a high quality winding with excellent insulation and heat transmission properties. -The rotor is the squirrel-cage type. -The capacitor is supplied as standard. -Surface protection of the electric motor assembly is achieved by a complete treatment cycle, including rust-proofing,pickling,phosphatizing,passivation,two coat paint finish applied by and electrostatic process and oven baked. NAME PLATE showing all the main electrical and mechanical characteristics and electrical connection diagram. PROTECTION IP 23.
