Delphi Eff2/Eff1, IE2/IE3 Motors

 
Delphi Eff2/Eff1, IE2/IE3 Motors
 

Rotomotive asynchronous three phase Delphi series motors are built with dimensional conformance to Indian Standard IS:1231, IS:2223 & International standard IEC 71-1.

The mounting positions as per IS:2253 and IEC 34-7 are B3, B5, B14 and B35.

Rotomotive motors are totally enclosed and fan cooled. Non standard versions in TENV construction are also available on request.

The frame size upto 132 are made from light weight die cast aluminium alloy and from size 160 upto 355 frame and end-covers are made from cast iron.

Multiple Voltage IP55 protection (IP56, IP66 on request)
Multi-Frequency 50/60 Hz 1 or 2 Efficiency Class
F Class Insulation (H class on request) IE2 or IE3 Efficiency Class (IEC 60034-30)
S1 Continuous Duty Service Tropicalized Winding

Energy Efficient EFF1/EFF2 Motors

Delphi series energy efficient asynchronous squirrel cage induction motors with EFF2/ EFF1 efficiencies are manufactured conforming to lS:1 261 5-2004. 

The enclosures, mounting and voltage supply conditions and tolerances are similarfor both EFF2 & EFF1 motors. 

EFF1 motors can be easily recognized by name plate & RAL5007 blue colour on terminal box cover in 71 -1 32 frame size & RAL9006 silver colour on terminal box cover in 160frame 

For EFF1 motors nearly uniform efficiency from 60% to 1 00% of rated load 

Energy Efficient IE2 & IE3 Motors
Delphi series energy efficient asynchronous squirrel cage induction motors - high efficiency IE2 & premium efficiency IE3 are manufactured conforming to IEC-60034-30. 

The enclosures, mounting and voltage supply conditions and tolerances are similar to Delphi Series EFF2 motors. 

IE-2 motors can be easily recognized by name plate & RAL5007 blue colour on terminal box cover in 80-1 32 frame size & RAL9006 silver colour on terminal box cover in 160 & above frame size.

IE-3 motors can be easily recognized by name plate & black colour on terminal box cover in 80-1 32 frame size.

Rotomotive asynchronous three phase Delphi series motors are built with dimensional conformance to Indian Standard IS: 1231, IS:2223 & International standard IEC 71-1.
