Due to its mechanical design flexibility, M Line (Master) motors can be applied on a wide variety of applications with different operational requirements. In addition, the M Line can be easily modified to match existing motors.

M Line motors are manufactured in different configurations in reference to cooling methods and degree of protection. As a result, a motor configuration can be defined in such a way to better meet operating and environment conditions. Motor supplied in frame sizes IEC 280 to 450 (NEMA 4400 to 8000) are manufactured in cast iron frames. Those motors manufactured in frame sizes IEC 500 (NEMA 8800) and larger have their frames built in welded steel plates.

H Line (High Performance) motors have been designed in such a way to withstand the most demanding applications and are regarded as both a reliable and low maintenance cost solution under such conditions.

With simple and compact construction, H Line motors are widely used due to their high reliability making them suitable for the majority of the driven machines found in industries. The frame construction consists of a high resistance solid block and it is fitted with external cooling fins. The whole cooling system, which consists of an internal and an external air flow provides a homogeneous blow of cooling air inside the frame for maximum performance of such motors.
