 ZS Series Air Cooler Motors

Detailed Product Description

OPERATING LIMITS
5% rated voltage
Ambient temperature up to +40
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.
