IE2, IE3 or IE4, IP55, multiple voltage multi-frequency, S1 cast-iron frame
Motive three phase motors from size 160 up to size 355 are made in cast-iron and have all those main features of the Delphi series, among which:
- standardized dimensions according to International standards (IEC 72-1)
- multiple voltage and multi-frequency 50/60Hz,
- F class insulation, [upon request H or H+ (delfire)]
- S1 continuous duty service,
- IP55 protection (IP56, 66 and 67 on request)
- tropicalized winding and reinforced insulation
- suitable for inverter power supply [from 110kW and up we recommend to order the motor with insulated barings (option)]
IE2, high efficiency class IE 60034-30
IE3, premium efficiency
IE4, super premium efficiency
Keeping the same sealing system of the whole delphi series, the terminal box up to size 280 is made in aluminum, thus guaranteeing its IP65 protection index without being affected by the usual finishing imperfections of the cast iron
From size 160 up to 280, we mount ZZ auto-lubricated bearings, thus avoiding the need of a periodical regreasing maintenance
Instead, from size 315 and up, they are provided with lubricators. 4, 6 and 8 poles motors drive end bearings are in fact of open roller type, in order to withstand eventual extraordinary radial loads (see paragraph "components list")
provided with 3 PTC thermistors that protect the motor and the system by operation anomalies
equipped by lifting eyebolts [one for B3 version (feet fixing), two for B5 version (flange fixing)]
The terminal box can be rotated of 360° with steps of 90°
