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, [oupon 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 wev recommend to order the motor with insulated barings (option)]
IE2, high efficiency class IEC 60034-30-1
IE3, premium efficiency class IEC 60034-30-1
IE4, super premium efficiency class IEC 60034-30-1
Keeping the same locking system as the entire delphi line, the junction box guarantees IP65, made of aluminium up to size 280, to avoid the usual shape defects of cast iron castings.
From size 160 to 280, we fit self-lubricating ZZ bearings, thus avoiding the need for regular relubrication maintenance.
On the other hand, from size 315 upwards, they are equipped with grease nipples and, with the exception of two-pole motors, with roller bearings to withstand very high radial loads (see "parts list" section).
3 standard PTC thermistors protect the engine and system against abnormal operation.
Fitted with lifting eye bolt (one for form B3 (foot mounted), two for form B5 (flange mounted)).
The terminal box can be rotated of 360° with steps of 90°
