These closed, externally ventilated type motors have dimensions and designs in accordance with IEC standards.
The advantage of these motors is the total absence of maintenance which, together with the possibility of having a precise speed control, makes them suitable for a wide range of applications where speed regulation independent of load values is required.
Our synchronous reluctance motors are of the self-starting type like conventional asynchronous motors and can be designed for very high speed applications.
The series name identifies the combination of materials of the main mechanical components of the engine (case and endshields):
