The areas of application for the 1PH asynchronous motors are extremely varied.
In machine tools, they are usually used as main spindle motors.
In production machines, such as printing, packing and reforming machines, they are used as high-output asynchronous servo motors.
The motors are referred to generally in this documentation as asynchronous motors, due to their principle of operation.
Core types can be supplied for certain motor types. These core types can be express delivered as replacement motors in the event of plant outages and offer the advantage of a quicker spare parts supply. For this reason, core types should be used for configuration wherever possible.
