Electric Motors & Spares

Non-flame proof motors

Salient Features of the Siemens motors

High Pressure Aluminium Die-cast Rotors all the way up to 400 Frame:

• Enhanced Starting Performance

• Enhanced reliability due to robust construction

as compared to the brazed copper rotors.

Salient Features of the Siemens motors

Original design of Side mounted Terminal Box:

• Conversion from Left to Right & Right to Left possible at site

• Conversion without rotor removal means quicker and safer interchange

Salient Features of the Siemens motors

Motors in frames 160 - 355 equipped with:

• Identical 63 series bearings at both ends

Benefits to the user…

• Reduced bearing inventory

• Longer overhauling intervals

• Easy maintenance

Frame / Stator Construction

Seamless, joint free casting with integral feet Top TB Position in front- Does not block air flow
CHAMPION Series motors for frame sizes 280 and 315 are provided with one size larger terminal box as a standard features.
Horizontal ribs-Better cooling

Rotor Skewing

Salient Features of the new motor series

Dual Mounting Holes at NDE for relevant IEC Frames:

• Motors of higher rating can be retrofitted in the existing    foundation. A great advantage to the user.

Cooling improves efficiency as well as the life of the motor
