The stator core is laminated with high quality electrical steel with high permeability and low losses allowing the motors to operate more efficiently.
The stator windings utilize Class F insulation (Class H insulation is available on request)with polyimide enamel round wire and VPI treated providing strong mechanical support, superior electrical insulation, misture and contamination resistance, and uniform heat dissipation.
Thermistors(PTC) are embedded in windings (Thermostats are available on request), one each phase.
The squirrel-cage totors are of cast aluminum alloy. fixed on the shaft by means of hot fit. The rotor is dynamically balanced to reduce vibration.
