Motors for extreme temperatures

Power outputs0,12 - 45kW
VoltagesUp to 690V
Frames63 - 280
SectorsFood / Industrial / Snowmaking / Steel Industry
Most common applicationsMachine tools / Fans / Pumps / Snow guns / Rolling tables on steel industry

The materials and protections with which we equip these machines ensure the correct functioning of the motors even in very severe temperature conditions.
We support you in choosing the configuration that best meets the characteristics of the installation in which these motors will operate.

The series name identifies the combination of materials of the main mechanical components of the engine (case and endshields):
